The SR 54-1 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 e-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. The relays contacts are gold plated and have a 2 amp restive load rating at 28 VDC. Coil current is 120 mA.
