The ATC Diversified ARM-120-AGE is a quadraplex alternating controller for a 120 V AC supply. Its float or pressure switches bring four loads on one after the other, and it drops them all together when the off switch opens; the lead load alternates every cycle, so the run time evens out.
Inputs: five intrinsically safe switch inputs: off, lead, lag, 2nd lag and 3rd lag. Inrush delay: 5 s between load starts. Supply tolerance: ±10% of nominal; 50/60 Hz. Power: 2.5 VA.
Output: 4 x SPST-NO (one per load), 5 A resistive at 24 or 120 V AC per channel; 278 VA inductive. Mounting: surface mount, #8-32 screw terminals. Indicator: An LED per output, on when the output is on. Approvals: UL Listed (E151578); intrinsically safe inputs per UL913 (7M26). It operates from -20 to +55 °C and stores from -40 to +85 °C.
