The HOA-100 is a 4 Channel Hand Off Auto Board designed to pass a voltage signal in auto mode, provide an adjustable voltage signal in hand mode or provide a zero voltage signal in off mode.
The HOA-100 uses an industry standard half wave bridge power supply (terminal #2 of AC supply and the input/output signal commons (-) are connected). Each channel has its own H-O-A toggle switch and potentiometer for independent control.
CAUTION: Care should be taken to avoid connecting both 24VAC and input to a controller device that utilizes a full-wave bridge rectifier (or floating common). Mixing half-wave and full-wave bridge rectifier devices on the same 24VAC supply will damage the full-wave bridge rectifier devices when commons are connected.
The HOA is also available in a 2 channel. See HOA-102S.
