Circuits monitoring device - Devices for monitoring safety-related circuits are also referred to as emergency stop switching devices or safety relays. But what is the difference to a normal switching relay? You will find out in the following sections. Rely on quality and equip your safety-related circuits with high-quality emergency switching devices from the eibabo® online shop.Image: Pilz PNOZ XV2 emergency stop switching deviceWhat are safety relays?Despite automation, people are always involved in the implementation of technological processes. Safety at work plays a central role in this. By selecting suitable protective measures, the risk of endangering the health or life of people in the working area of a machine can be reduced. The most important protective elements include safety relays. Their task is to switch off the power supply in the event of a fault, danger or defect. This protects the life or health of the operator and prevents damage to the machine, the facility or the system.Originally, safety circuits were equipped with a single electromechanical contactor and combined with a circuit-connected safety switch. However, this variant did not offer complete protection. If, for example, the contacts of the contactor stuck together, the machine or system continued to run despite the safety switch being actuated. The solution to this problem was to add an additional contactor to the circuit. This already reduced the probability of errors, but still did not provide complete protection. Electronic devices were therefore developed which were equipped with at least two relays and a microprocessor system. A safety relay is therefore protected several times and automatically checks with each switching cycle whether its own safety device is still working properly. Even if a component fails, the safety device remains effective. The function of these safety relays henceforth made it possible to eliminate the risks associated with the use of a single contactor while knowing the status of input devices and output devices.Where are circuit monitoring devices used?The classic place of use for circuit monitoring devices is industrial systems. These devices are used wherever a workplace is potentially dangerous due to moving parts of a machine. The following safety circuits are the most common:The emergency stop switchThe emergency stop button is a large, robust and strikingly designed button that you can use to manually activate the safety relay and bring a machine to a standstill in the event of a hazard.Tip for saving:Complementary to circuit monitors are emergency stop switches and other components to create a complete safety device. Benefit from our low prices and save costs with combined shipping.Two-hand operationAs the name suggests, a circuit in this circuit is only closed when you press two different buttons with both hands. This is to prevent you from accidentally reaching into a rotating machine, for example. As soon as you release one of the two buttons, the safety relay stops the machine.protective doorsDangerous working areas are often provided with protective doors. Opening such a protective door triggers the safety relay, which then immediately interrupts the circuit. The machine stops.Light grids / light barriersWhere no protective doors or other physical barriers can prevent access to dangerous areas, the safety regulations are implemented using light grids or light barriers. If an object enters the monitored danger area, the safety relay is triggered and the machine stops.How is a safety relay structured?The typical structure of the safety relay uses a classic combination of 3 contactors. This system redundancy provides increased device reliability. Two relays ensure safe contact switching. Each is driven by one of the two input circuits. The operation of these circuits is not only determined by the signal present at their outputs, but is started by the starting relay. Between its outputs there is a control circuit (also a monitoring circuit) which checks the position of the actuators to be controlled and switched. What does that mean? After switching on, the device carries out a self-test. The input devices are checked first. If their circuits are closed, a safe state has been reached. The output devices are then checked. Here, too, the safety relay waits for a start signal, upon receipt of which the output devices are activated. The safety functions of the relay are now also activated and the device is ready to fulfill the required safety tasks.What are the advantages of programmable safety relays?There are applications where a conventional safety relay would not suffice. In such cases, using a programmable safety relay can be an excellent alternative. This is especially true in more complex systems where using a traditional relay would be cumbersome or impossible. Programmable safety relays are also referred to as control devices for circuit monitoring or programmable logic controllers (PLC). In a nutshell:Programmable logic controllers are devices that allow you to implement more safety functions than individual relays. While a separate safety relay is used for each device by default, one PLC can secure multiple devices. This saves a lot of space in the control cabinet. You can also use it to control processes that can be changed or corrected at any time. The programmable safety relays consist of input modules and output modules as well as a central unit. A processor executes the control algorithm stored in memory based on the data read from the input modules. The control signals are then sent to the output modules. These forward the signals to the corresponding actuators, which are connected to the relay outputs. Programming is done using a computer and the appropriate software or via the built-in keyboard or display. PLCs are most commonly found in modern security systems where sophisticated communication and complex data exchange takes place.Based on your requirements, you can now assess whether an emergency stop relay or a PLC is right for your application.

Current monitoring device - If you would like to be in control of your electrical installation, then monitor your cables and wires for correct function and proper current flow. Especially if you want to minimize downtime or failures within production processes, you can counteract any problems early and effectively with a current monitoring relay. Learn more about the types and uses of power monitoring devices here. Use our help when making a purchase decision and choose from numerous quality products at top conditions here in your eibabo® shop.Analysis and EvidenceHigh-quality current monitoring devices are able to store errors that occur for later evaluation, to communicate with other components and, if necessary, to send out alarm signals.Devices of this type are typically installed in the control cabinet and use suitable relays to protect your system against undervoltage or overvoltage or against undercurrent or overcurrent.What types of surveillance devices are there?A monitoring device is a protective relay that is used to monitor various states of an electrical system. It is therefore an electrical switch which is triggered when certain specified parameters are exceeded. The device provides protection by shutting down the system in the event of an abnormal condition. A monitoring device (also called a control relay) typically consists of two main components: a sensing circuit for detecting condition and a trigger element. The detection element is used to determine the monitored parameters. The triggering element serves to trigger the switching process.Individual settings can often be made by the user with these devices. The protection parameters can thus be adapted to the requirements of the respective system. This is done using adjustment wheels and screws or, in the case of digital relays, using buttons and a display. Among other things, the following can be set:Delay ? to avoid false alarms due to sudden power surgesReset (manual or automatic) - used to reset the electrical system after a shiftRemote Reset - to remotely reset the electrical system after a shiftAlarm ? to trigger an alarm in the event of a trip Surveillance devices fall into different categories. These are based on the parameter being monitored. This can be voltage and current, but also filling levels or temperatures. The most common monitoring devices are:Voltage monitors - trip when the voltage in an electrical system exceeds and/or falls below a specified level.Phase monitors ? are used to monitor and protect against polarity reversal, phase failure and phase asymmetry. These constantly check the phase difference between two or more phases.Current monitors - protect equipment in an electrical system from overcurrent or undercurrent. Current monitoring relays trigger when the current exceeds or falls below a predetermined value.Frequency Monitors - Used primarily in Alternating Current (AC) systems where line frequency control is required. These relays are therefore used to protect against frequency anomalies.Temperature monitors ? primarily protect against overheating by constantly monitoring the temperature of the system and the devices that are being protected. Areas of application are predominantly industrial plants where extreme temperatures are a problem.Level monitors - are switches for level control in cisterns, tanks and other storage containers. These devices are used wherever liquid levels need to be monitored. Image: Pilz S1IM #828050 current monitoring relayThe different types of current monitorsCurrent monitors are important devices when it comes to protecting electrical systems. These help prevent damage to equipment and components by shutting off a circuit in the event of a fault. There are different types of electricity monitors. Each has its own advantages and areas of application. Depending on this, please select the right type to ensure proper protection.Primary and secondary power monitorsPrimary devices are mostly part of a circuit breaker and are mainly used in electrical networks with voltages up to 1000 volts. Secondary current monitors are connected to the circuit through a current transformer, which in turn is connected to the power supply. The current transformer reduces the current to a value suitable for the function of the monitoring device. Secondary current monitors are in turn divided into the following subspecies:Electromagnetic DevicesThe devices based on the principle of electromagnetism are the most common. These consist of a core with a copper winding and an armature with attached switch contacts. When the current is off, a spring keeps the armature away from the core. When a voltage is applied, a magnetic field builds up around the core. This attracts the armature and thus switches the connected contacts. The majority of electromagnetic devices are so-called polarized relays. These contain two cores with windings, a permanent magnet and a contact rod. Operation is dependent on the polarity of the input signal. There are electromagnetic relays for alternating and direct current. Their advantages lie in high-quality galvanic isolation, low price, low contact voltage drop and low heat development. No refrigeration is required. Devices of this type are resistant to impulse loads and interference from lightning strikes. The main disadvantages are the limited mechanical and electrical service life and the low operating speed.induction relayThe principle of operation of induction relays is based on the interaction between the current induced in a conductor and a variable magnetic flux. Therefore, with alternating current, these are used as indirect protection relays. The integrated components of the device are arranged in such a way that they are aligned with each other at the set frequency of the current and are not deflected. When the frequency changes, a moving element moves, causing the contacts to close or open. We distinguish between induction devices with a frame, with a pane and with glass.differential relaySuch devices compare the current strength before the consumer and after it. This consumer is usually a power transformer. In the normal state, both values are approximately the same. However, if a short circuit occurs, this balance is disturbed. As a result, the relay closes the contacts and turns off the faulty section of the circuit. Often found in household appliances and lamps, these relays protect people from electric shock.Relays on microcircuits in the integrated electronicsThe devices work with semiconductors such as triacs or thyristors. In the basic principle, such a device compares the incoming signal with the parameters stored in the device for trouble-free operation. If there is a deviation, the relay breaks the circuit.thermal relayThermal relays work with an integrated bimetal. This heats up when an electric current is passed through it. If the current flow deviates from the specified value, the bimetallic strip deforms, causing the contacts to open and close.What should you look for in a current monitoring device?In order for the current monitor to work, its parameters must meet the requirements of the assigned tasks. When selecting a device, pay attention to the following features:Voltage in volts - this is the voltage range in which the device normally operatesCurrent in amperes - each device is rated for a specific currentTripping power in watts - this is the minimum power of the electrical current supplied for normal operationControl power in watts - this is the maximum power of electric current at which the relay will perform its functions correctly  TIPWhen making your selection, pay attention to the prevailing operating conditions. Is the device used in critical environments with high humidity, dirt, heat, cold or vibrations? Furthermore, the error detection depends on the accuracy of the measurement of the current strength in amperes. The response time of the device is another important parameter. How long does the device take from the moment of the event to triggering? Under certain circumstances, it can be advantageous to be able to individually set a delay before switching the device on or off for critical loads.As a specialist for smart home technology, we at the eibabo® online shop are your competent partner for all questions relating to intelligent electrical installation.

Insulation monitoring device - How does an insulation monitoring device work and where do I have to use it? What does the device protect against and what advantages does it offer me? Read here why the correct insulation of an electrical system is an essential prerequisite for its safe operation. Protect yourself and your system with high-quality measuring devices and reliable testing technology from the eibabo® online shop.The History of Insulation Monitoring DevicesThe first insulation monitoring device was invented by Walther Hans Bender in Frankfurt/Oder in 1939 and a patent was applied for. It was a device for three-phase systems in brown coal mining. In 1952 the 'Isometer' was protected as a trademark and has belonged to Bender GmbH & Co. KG ever since.Image: Dold IL5880.12 insulation monitorHow does an insulation monitoring device work?An insulation monitoring device is also referred to as a ground fault monitoring device. Connect this between your active power lines and the earth line. With continuous insulation monitoring, you can discover weak points in the insulation of your electrical systems. These can be caused, among other things, by moisture or by age-related fatigue of the material. You want to detect a problem like this before voltage breakdown occurs. Voltage breakdown will damage the insulator and cause sparks or arcing, which can lead to power failures, fires, property damage, and personal injury.The device sends a measuring voltage to your system and monitors it. If there is a ground fault, the measuring circuit between the mains line and the ground is closed. A measuring current proportional to the earth fault thus occurs. A voltage drop occurs at the measuring resistor of the device. Conversely, this means that the insulation resistance of the system is reduced. The insulation monitor registers the change and evaluates it. It is not only the resistance itself that is important, but also its course over time. In the case of undamaged insulation, the insulation resistance asymptotically approaches a certain reference value. term asymptoteA value behaves asymptotically if, over time, it approaches a reference value without ever reaching it. If the insulation resistance falls below the reference value, this is an indication of the increase in the conductivity of the insulator. From this it can be concluded that the insulator has changed chemically due to external influences or that its material is gradually enriched with decomposition substances. If a critical point is reached, the device sends a message. This allows you to recognize the deterioration of the technical condition of the insulation at an early stage and to take the appropriate steps for repair or maintenance in good time.Where is the use of an insulation monitoring device required?The measurement of the insulation resistance is used in local low-voltage networks without an operationally grounded star point (so-called IT power supplies).For explanationBasically, low-voltage systems are divided into TN systems, TT systems and IT systems. The main difference lies in the way of grounding. While residual current is used for monitoring in TN systems, insulation monitoring devices are used in IT systems.Modern insulation monitoring devices have a history memory and record the insulation resistance measurements. The data can be called up later and serve as suitable monitoring evidence during controls.What are the advantages of insulation monitoring devices?With insulation monitoring devices, you continuously monitor safety-relevant circuits for residual currents and residual currents. This results in a number of advantages in daily use:Measurement without switching off ongoing operationsReducing the risk of failure and increasing the availability of monitored electrical systemsReduction of electromagnetic interferenceReducing the risk of fireSaving of time-consuming and expensive maintenance and repairs You also prevent the safety of people and machines and thus avoid accidents, property damage and personal injury.Which manufacturers offer high-quality and reliable insulation monitoring devices?In the eibabo® technology store you only get quality goods from well-known manufacturers.

Base unit - In industrial technology, automated processes are no longer possible without programmable logic controllers. If you would also like to set up automated processes, the following article will give you a brief overview of this modern technology. At eibabo® you get a variety of:Basic devices for PLC controls, for Alpha XL and Siemens Logo!Basic devices and CPU compact devicesCPU central assemblies and fieldbus controllersInline controllers and control units Today, these devices are used in all industries, both in large and small automation systems.What are Programmable Logic Controllers (PLC)?A controller in automated systems carries out the control of physical processes in accordance with an underlying algorithm. For this purpose, it uses information received from sensors and output to end devices. Every automatic device has a control controller - a module that determines the logic of the device.What are programmable logic controllers (PLCs)?Programmable logic controllers (PLCs) are real-time devices for automating technological processes. The PLC is programmed digitally and can therefore be easily adapted to the requirements of a specific process. With the increasing demands on modern machines and production processes, PLC automation solutions have become indispensable in everyday industrial production. The main areas of application of the PLC are in their long-term use without the need for human intervention. PLCs are generally used to control sequential processes. The status of an object is determined by means of input signals and output parameters and corresponding control actions are carried out.The History of Programmable Logic Controllers (PLC)Before programmable logic controllers emerged in modern form, their development began with comparatively simple ladder logic in the middle of the last century. With the advent of microprocessor technology towards the end of the 1960s, industrial automation processes were also directly influenced. Digital circuits developed, which have since been used in automatic control systems.In 1968, a group of engineers at General Motors were tasked with making easily programmable industrial controllers. These should be easy to maintain and repair. A modular design should also make it possible to replace the installed modules or add new modules. The world's first programmable logic controller was called 'Modicon 084' and was presented in 1969. The device weighed about a hundredweight and consisted of a cabinet with a number of modules whose storage capacity was just 4 kilobytes. Already knewThe invention of the first PLC is credited to American engineers Richard E. Morley and Odo J. Struger. In 1970, the world's first automated control system based on this controller was presented at the Chicago Machine Tool Show.Where are basic PLC devices used?Programmable logic controllers offer a simple and cost-effective solution for many automation tasks and are the ideal solution for the individual control of a wide variety of applications, machines, systems and processes or for digital power control. With any automation-based control system, the focus is on achieving the desired result efficiently and reliably. As part of process automation, they control robotic arms in the automotive industry, complex conveyor technology or processes in nuclear energy, transport and traffic.How is a basic PLC device constructed?A basic device for the programmable logic controller typically consists of the following components:Inputs for signal acquisition ? the device monitors the current status of the system via connected buttons, thermometers, tachometers or sensorsOutputs for signaling ? the devices of a system are connected here, with which the PLC executes a processSoftware ? the user program that is used to determine the switching of outputs depending on the activation of the inputsCommunication interface - this is used to connect the PLC to other systems The base unit also requires its own power supply and contains a processor and the internal bus.Mitsubishi AL2-24MR-A #215074 basic unitHow does a basic PLC device work?A programmable logic controller is a device that collects, converts, processes and stores information and generates control commands. Data is exchanged via inputs and outputs on the device. In this way, sensors, buttons, actuators and other devices can be connected to the control object. It is therefore a small computer, controlled by a microprocessor with its own operating system. This is adapted to the needs of solving automation problems in real time and works with the shortest possible response time. The PLC receives the signals from the controlled process via the inputs in the form of:On/off states - for example position detection by limit switches or proximity switchescontinuous analog signals - these include temperatures, pressure, speeds, levels and so on The devices that run the automated process are connected to the output side. These in turn receive the signals from the basic device in the form of:On/off control signals - for example for an electromagnetic relay, a motor contactor, a signal lamp and so oncontinuous analog control signals - for example to open or close valves or to adjust engine speeds The processor is located between the inputs and outputs. This is also called the Central Processing Unit (CPU) and controls the output signals based on the data of the input signals. Individual programming (using software for parameterization) can be used to determine how the PLC reacts to the input signals or their changes. This information is stored in the basic device. There is usually a separate interface on the device for this purpose. Another option is to connect the base unit to a network. Then communication within the framework of the network hierarchy with other peripheral devices and systems is possible.What advantages does a PLC have over a classic relay circuit?Over time, PLCs have adapted to the specific needs of the industrial environment. PLC functions have a number of advantages. Due to their flexibility, they can be used in a wide variety of industries. In addition to the possibility of remotely controlling a PLC, the greatest advantages lie in the ability to communicate and the individual programmability of the functional logic. The settings can be changed at any time without affecting the operation of the device itself. A PLC can usually be installed directly on a production machine.How do I choose the right basic PLC device?A large number of factors must be considered and evaluated when making the selection. By combining the technological requirements for a specific automation object with a comparison of modern programmable logic controllers, you can make the right decision. The selection of the right PLC depends, among other things, on the following criteria:system requirementsThe system requirements describe the task that the PLC should fulfil. Define the goals to be achieved and break them down into several simple and understandable steps. Determine the type of input devices and output devices to be connected to the PLC and their respective functions. Would you like to implement further special functions? How many inputs and outputs are required on the basic device? How much storage is required? What are your processor speed requirements?serviceMost PLCs are initially programmed with a computer. This is then no longer required to operate the PLC itself. Therefore, consider whether you want a PLC with an integrated display and touch panel. It can be enough to read the values and manage the system via the existing IT infrastructure.communicationIs the data exchanged with other devices outside of the actual process? Is the device part of a network?conditions of useIs the PLC exposed to special operating conditions that affect the properties and function or have an impact on reliability and maintenance intervals?electrical needsWhat are your power requirements for the individual inputs and outputs and for the PLC itself?operating speedThe speed of operation is responsible for the security and flow of 'time-critical' operations.Manufacturers of high-quality basic devices for the PLC include: Mitsubishi Electric, Pilz, Siemens, WAGO Kontakttechnik or Phoenix Contact.  Catalogue content:In this eibabo® catalogue PLC's > PLC CPU-module you will find items from the following product groups:Item overview:Bus controllerBus couplerBus participantsCommunicationControl accessoriesControl relayController boardControllersDecentralizedEADecentralizedIOExpansion moduleFieldbus componentFieldbus controllerFieldbus couplerFieldbus moduleFieldbus technologyGroup carrierHead stationInterbus tapInterfaceLogic moduleMain group carrierModular controlRectangular connectorRectangular plugRoom automationRoom controllerShip approvalfrom the following manufacturers:Manufacturer overview catalogue Base unit:ABBEatonMitsubishiOmronPhoenixPilzSchneider ElectricSiemensStahlThebenWAGOWeidmüller
Inductive proximity switch - Are you interested in an inductive proximity switch and would you like to learn more about how it works and areas of application? Would you like to buy an inductive proximity switch and are you looking for a reliable supplier with a large selection at top conditions? In addition to information, the eibabo® shop also offers you high-quality articles in the field of Smart Home, lighting, switch programs and electrical material. Of course, this also includes inductive proximity switches and many other types of position switches and limit switches.What are inductive proximity switches?Inductive proximity switches are used to detect metal objects in the working area of a sensor and to signal this by changing the switching status.StoryThe physicist Michael Faraday first described the principle of electromagnetic induction in 1831. He found that changing magnetic fields create electric current.Proximity sensors are used for automatic non-contact detection of metallic objects for various industrial purposes and work reliably even under difficult conditions and various external influences. When the sensor is supplied with electricity, a magnetic coil inside generates an alternating magnetic field. This magnetic field is the working range of the sensor. The principle of operation is based on the phenomenon of change in vibration amplitude caused by a ferromagnetic, magnetic or metal object of a certain size in the working area of the sensor. If you bring a metal object into this area, the eddy currents induced in the metal lead to a change in the original oscillation amplitude of the coil. The intensity of the change depends on the distance between the metal object and the sensor. This change is presented as an analog signal and is converted into a logic signal with a corresponding value. The switch itself is a semiconductor converter, which controls the circuit to be executed depending on the position of the object.How are inductive proximity switches constructed?The electrical part of the sensor is typically housed in a threaded metallic cylindrical housing or a rectangular plastic housing. The cylindrical metal housing is assembled using the thread. To do this, they are attached to bores in mounting plates using nuts or screwed directly into the sockets provided for this purpose. The sensors with a rectangular housing are fastened with screws at the place of use. In order to be able to withstand the conditions of the industrial environment, the technology is usually surrounded by a protective sealant. TIPThe electromagnetic field of the inductive proximity switch is very weak and harmless to human health. The switches are available for both flush and non-flush mounting. Flush sensors can be mounted without protruding beyond the mounting surface. However, these generally have a shorter sensing range or more restricted working range than non-flush sensors.What properties do inductive proximity switches offer?The properties of the inductive proximity switches can vary depending on the model, manufacturer, structure and equipment. In general, the devices offer the following functions and properties:reaction to metal onlyInsensitivity to other materialsTightness against water and dust / correspondingly high degree of protectionReliability and durability because the switch's working surface is not in contact with the objectCompact dimensions and low weightTrip indicator LED Image: Schneider Electric XSAV11801 speed monitorWhere are inductive proximity switches used?Inductive proximity switches are robust and withstand shock, moisture, vibration and dirt. Within an automation process, inductive proximity switches work as the primary control elements, taking into account the position of certain metallic, moving objects. Proximity switches are used particularly frequently on assembly lines in special machine construction and plant construction. These are used there, among other things, for counting and tracking metal objects. But the devices are also used in warehouse logistics and conveyor technology, in the packaging industry and in the automotive sector. Depending on the application, the signals from the proximity switch are evaluated by a counter, a motion controller, an alarm system or other devices. In addition to numerous other functions, the following are also:distance measurements madeMaterial thicknesses and material widths determinedChecked surface texturePosition checks carried outCounting tasks taken over The classic example are bottles with crown caps or beverage cans, which are transported past the sensor and counted on a conveyor belt.What errors can occur with inductive proximity switches?The reliability of the measurements of an inductive proximity sensor depends on its properties, the way it is used, the installation and the nature of the objects to be detected. The two main errors are:The item is not recognizedIf the object is not detected, please check the sensor properties and all distances. Pay attention to the switching distances and the switching function (opener or closer). Is the correct operating voltage present? Is the item made of metal? Is the item big enough? Is the object moving too quickly through the work area?The sensor switches too early or too lateIf the switching time is not correct, this is often due to critical environmental conditions or electromagnetic interference signals. Is the sensor installed correctly (flush or non-flush)? Were other installation conditions observed? Are other switches that are in the immediate vicinity interfering? Is the sensor dirty? Check if other metals affect the work area.The inductive proximity switches in the eibabo® range are all of high quality and are therefore also suitable for your planned application. Well-known brand manufacturers for inductive proximity switches are Baumer, Dietz, Festo, Kisling, Leuze, Metz, Pilz, Rockwell, Turck, Weidmüller and many others.  Catalogue content:In this eibabo® catalogue Sensors > Inductive proximity switch you will find items from the following product groups:Item overview:Analog sensorCable sensorCuboid sensorDC voltage sensorFour-wire sensorInductive sensorObject detectionPlug sensorProximity initiatorProximity switchRound sensorThread sensorThree-wire sensorUniversal voltage sensorUprox sensorfrom the following manufacturers:Manufacturer overview catalogue Inductive proximity switch:BaumerBernsteinDi-soricDietzEatonEGE-ElektronikElobauFestoGavazziHengstlerIfm ElectronicIpf ElectronicKisslingKlaschkaLandefeldLeuzeMetzOmronPepperl + FuchsPilzRockwellSchmersalSchneider ElectricSensopartSickTurckWeidmüller
