ATC Diversified ARM-120-AHE FOFO Output Logic Quadraplexor Controller

ATC Diversified, ARM-120-AHE, 120 VAC 4 Load FOFO Output Logic Quadraplexor Controller

Features:

• Intrinsically Safe Inputs

The special function models are differentiated by a rotary switch that allows any output to be locked as the lead load or any one load to be omitted while sequencing only the remaining loads. In addition to load omission and lead selection, the expandable model can be set for 2, 3, or 4 load operations with either SOSO or FOFO logic. All models feature Intrinsically Safe Inputs and logic that allows the outputs to operate properly even if one of the inputs fails to open or close. For example: if the off switch fails to close, the lead load will not energize until both the lead and the lag switches close. An inrush delay on all models reduces line sags by preventing Multiple Loads from energizing simultaneously.
