PIR-5 - Impulse Memory Relay

Developing of Impulse Memory Relay PIR-5 was based on required galvanic separation of pulse control outputs of telecontrol (P, Q requirements) and connected circuits of power generating plants. PIR-5 generates permanent memory control signal from pulse (about 1 second) telecontrol output of type "1 out of 5". The relay is designed as quintuple and selected command is active even during the power supply failure by using the bistable relays.
