Signal Transmission Equipment for Command Control - KEDR Transmitter for RF, LF, and Fiber Optic Applications

Apparatus for transmission of signals - commands of protection and PA through the channels: high-frequency, low-frequency and optical fibre. The set of equipment consists of a transmitter and a receiver installed at opposite ends of the communication channel. The TRANSMITTER receives control actions on discrete inputs and transmits command signals via the HF channel. Additional functions: Receiving data signals (TM) from the TM transmitter and transmitting them to the HF channel. Continuous monitoring of equipment and communication channel serviceability, formation of external signalling signals. Recording in non-volatile memory data events of alarm and command transmission; Exchange of information with the server of the control system via GOST R IEC 60870-5-101 or GOST R IEC 60870-5-104
