Functional Devices RIBL24B Relay 318973-401 This model is factory-set forFor high demand commercial HVACR and building automation projects, the Functional Devices RIBL24B Relay provides a robust solution for switching 20 amp loads with a low voltage 24V signal. As an enclosed mechanically latching relay, this unit is engineered for energy efficiency; the contacts remain in their last known state during a power loss, eliminating the constant coil draw associated with standard pilot relays. This SPST configuration is ideal
