Shunt resistor ShRB, ShRR, ShRKI (device for shunting discrete inputs of terminals and high-resistance relays with insulation monitoring function).
"ShR" is designed to increase the noise immunity of high-impedance discrete inputs of microprocessor terminals RP and ECS, to ensure the operation of general substation signaling of ground faults between information contacts and a high-impedance discrete input, LED indication of the presence of an input action, implementation of the received information to the object recorder.
