ATC Diversified, ARM-2003, 120V AC Surface Mount Duplex Controller without H-O-A Switches
Features:
- Two Pump Sequence
- Intrinsically Safe Inputs
The ARM Series Alternating Relay is a microprocessor-based controller designed for use in dual-load installations to assure equal run time on each load. LED indicators show the status of the unit's five intrinsically safe control switch inputs, one alarm, and two load outputs. H-O-A switches, a lead select switch, and a test/clear button are provided for manual control. The ARM Series reduces the number of components required for this application by combining many functions into one unit.
