نقد و بررسی تخصصی IS200TRPGH1BDE
VTUR provides the primary trip function by controlling the relays on TRPG, which
trip the main protection solenoids. In TMR applications, the three inputs are voted in
hardware using a relay ladder logic two-out-of-three voting circuit. Relay coil
currents, contact status, and supply voltages are monitored for diagnostic purposes.
