Signal Transmission Equipment for Command Signals RZ and PA AK "KEDR" Receiver Purpose/Applications

Apparatus for transmission of signals - commands RZ and PA through 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 receiver receives command signals from the HF channel and outputs them to the corresponding discrete outputs. Additional functions: Transmission of data signals (TM) and transmission to the TM receiver. Continuous monitoring of equipment and communication channel serviceability, formation of external signalling signals. Recording in non-volatile memory data events triggering alarms and receiving commands; Exchange of information with the server ACS on the protocol GOST R IEC 60870-5-101 or GOST R IEC 60870-5-104
