Plug-In Duplexor

ATC Diversified Electronics, a division of the Marsh Bellofram Group of Companies, has the ARC/ARD Series is an 8-pin plug-in Duplexor, featuring sequence on simultaneous off (SOSO) three-input functionality. The duplexor is designed to detect float switch inputs, from which it determines the necessary outputs to turn on with line voltage. As the lag and lead switches open, the load remains energised. When all switches are open, both loads de-energize simultaneously and the lead load alternates. The ARD series has a three-position switch from which it provides the option to lock it either into normal duplexing action, 1-2 sequence or 2-1 sequence. Units feature a 120 V AC control voltage, as well as SPDT two-line voltage outputs with a contact rating of 10 A 1/3 HP @ 120 V AC (combined output). They are easy to install and maintain, and feature UL recognized cURus. Typical applications for the ARC/ARD Series include water and wastewater, lift stations, water feeding, municipal water and wastewater treatment facilities, and industrial pumps.
