SR54-1 Switching Module | 5 Relay, 20 Pole Switching 1510 and has a free-hanging mountingThe SR54 1 switching relay provides 20 poles of switching through five hermetically sealed, bifurcated relays. The SR 54 has a built in circuit that switches all relays to their de energized condition whenever K6 is activated. This can be used for such applications as insuring LOC is presented on the HSI whenever a LOC signal is selected.
