"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. 

 

The "DIPU" is designed to indicate the operation of the relay protection and the control in direct current  and  implementation of the received information to a common recorder, and signaling of the power facility.

 

«ORION» ARS is designed to indicate the operation of relay protections(RP) and emergency control schemes(ECS), shunting high-resistance input sensors of microprocessor terminals, implement the received information to the terminals, as well as to the centralized alarm system of a power facility. Functionally it completely replaces outdated signaling devices (RU-21, REU-11, ES, etc.).
