Functional Devices RIBL24SB : Enclosed Mechanically Latching Relay, 20 Amp Contact Rating, Relay Contact Type: SPST + True Override, 24 Vac/dc Coil Voltage, NEMA 1 Housing

Functional Devices RIBL24SB : Enclosed Mechanically Latching Relay, 20 Amp Contact Rating, Relay Contact Type: SPST + True Override, 24 Vac/dc Coil Voltage, NEMA 1 Housing

Functional Devices Latching Relays are switched by pulse commands from an appropriate power source or a controller. The relay contacts are mechanically latched in position, so that the load remains in its last state (on or off) during a loss of power. A pulse of opposing polarity latches the relay in the alternate state.
