The HDR-11 is used for control of lighting circuits and other electrical loads in Wattstopper's Peanut Panels, Lighting Integrator Control Panels and Lighting Management Control Panels. Momentary, low voltage signals from the panel's control system switch the relays on or off. Mechanical latching operation results in lower power consumption and ensures the relay will remain in the last switched state in the event of a power loss. A built-in manual actuator allows the relay to be turned on or off in the event of a panel failure. The relay mounts into a standard 1/2”” knockout and comes with a 5-pin phenolic connector for easy panel connection.
