Additional Features, Controls or Alarms

Inhibit Input - When shorted (<1V @ 2mA) to the -VDC inhibits the DC output voltage. When Open (I<0.1mA at 5Vdc) enables the output voltage.
Parallel Operation: When using two or more identical M286 units in parallel, all PARALLEL Pins should be connected together.
BIT Operation: The output side (collector and emitter) of an optoisolator. Active Low (V<0.8V @ 2mA) when DC output voltage is OK, Open (I<0.05mA @ 5V) when DC output fails.
