4.3.3 Sinking / sourcing input configuration

All DSMS17, 23 and 34 models can be wired to create sinking inputs, where a reference voltage between +5 and +24 VDC is connected to the Optocoupler Reference (white) lead. The isolated inputs are then interfaced to a sinking output (which utilizes the same supply as the opto coupler reference input) such as a switch, open collector, or PLC output. To maintain isolation, the input power source should not be connected to the motor power source.

Alternatively, sourcing inputs may be used where the Optocoupler Reference (White) lead is connected to ground. The isolated inputs are then sourced to between +5 to +24 VDC from a switch, open collector, or PLC output.
