Temperature measuring device 12 measuring points - Accessories for safety equipment 7XV5662-6AD10 – Siemens – 4025515639978: Temperature measuring device 12 measuring points 7XV5662-6AD10 The communication converter for coupling to a communication network is a peripheral device connected to the protection device via fiber optic cables, which enables serial data exchange between two protection devices. This takes place via a digital communication network. The electrical interfaces for access from the communication converter to the communication device are either X.21 (64 kbit/s, 128 kbit/s, 256 kbit/s or 512 kbit/s) or G.703.1 (64 kbit/s). The data is converted at the remote station by a second communication converter so that it can be read by the second device. With the help of the communication converter, two protection devices can communicate with each other synchronously and exchange a large amount of data over long distances. Typical applications are the serial protective interfaces of the differential protection and the distance protection with the SIPROTEC 4 devices 7SD52/53, 7SD61, 7SA52, 7SA6, and all SIPROTEC 5 devices such as 7SD8, 7SA8 and 7SL8, for which 7XV5662-0AA00 must be used. If asynchronous serial data of the 7SD51 differential protection or the 7XV5653 / 7XV5673 binary signal transmitter is to be transmitted, the 7XV5662-0AA00 device must be used (asynchronous from 300 bit/s to 115.2 kbit/s depending on the Bd rate of the X.21 or G .703.1 interface). The connection to the protection device is interference-free via a multimode fiber optic cable, which is assembled with ST connectors on the communication converter side. The maximum optical transmission distance is 1.5 km. The 7XV5662-0AA00 should be assembled or installed near the communication device or DUE (data transmission equipment) in the same cabinet or at least in the same room. The electrically bridgeable distance should be kept as short as possible, a few meters are advantageous. The data transfer between the protection devices represents a point-to-point connection that is bit-transparent. The data exchange must run via reserved communication channels in the same communication system.
