| Datasheet | Download Datasheet |
The ATC Diversified ARA-120-AHE is a triplex alternating relay for a 120 V AC supply. It rotates three loads, moving the lead to the next load each time the control switch opens, so they share the run time evenly.
Inputs: a control switch (2 mA); remove the factory jumper to clock the alternation from an isolated normally open switch instead. Selector switch: four-position: normal, or omit load 1, 2 or 3 (the other two duplex). Supply tolerance: ±10% of nominal; 50/60 Hz. Power: 3 VA.
Output: 3 load outputs, 5 A resistive, 1/6 HP, 211 VA inductive at 120 V AC per output. Mounting: surface mount, #8-32 screw terminals. Indicator: LEDs show the condition of each output. It operates from -20 to +55 °C and stores from -40 to +85 °C.
