Control unit video bus system 128800

Control unit video bus system 128800 – Gira – 4010337288008: Video bus system control device, REG, 8TE 128800 video application, input voltage 230V, frequency 5E-6 ... 5E-6MHz, type of current AC, output voltage 12V, degree of protection (IP) IP20, bus system installation technology, integrated door release circuit, control function, number of connectable Subscriber 18, DIN rail mounting type, REG video control device Features: Control device for supplying the audio and video components of the Gira door communication bus. Supply of the polarity reversal and short-circuit proof 2-wire bus when using video components such as color camera, TFT color display. Up to 2 door stations with color cameras and 28 home stations with TFT color displays can be supplied via the video control device. A total of up to 15 color cameras can be controlled by the video control device (5 video door stations and 10 DCS camera gateways), of which two door stations with color cameras can be supplied with power from the video control device. The other color cameras must each be operated with their own power supply for door communication. Self-resetting electronic short-circuit and overload detection of the operating voltages and the bus connection. Buttons for system and door opener programming. LED status indicators for operation, overload, system programming and door opener programming. AC 12 V output for the power supply of a standard door opener. Relay output for switching a door opener with its own power supply. Door opener switching time continuously adjustable from 1 to 10 s. Notes: The video control device is intended for installation in the sub-distribution, not for commercially available surface-mounted distributors. If the topology of the video cabling is designed as a stub line, the video distributor is also required. The power supply for door communication is required in combination with the DCS-TK-Gateway. With the video control device, it is possible to set up door communication systems with up to 70 audio participants (e.g. 1 x built-in loudspeaker, 5 x extension module for built-in loudspeaker, 68 x surface-mounted home station).
