The Relay Logic Series™ (RLS) Duplex control panel provides a reliable means of controlling two alternating 120, 208, or 240V single phase pumps in pump chambers, sump pump basins, irrigation systems and lift stations. The alternating action equalizes pump wear. This system provides override control should either pump fail.

Magnetic motor contactors are used to turn the pumps on and off. If an alarm condition occurs, an alarm switch activates the audible/visual alarm system. Standard components are used allowing for easy troubleshooting and service.
