3.6. Opto-Isolated Outputs
The outputs are software configurable as sourcing or sinking. The outputs are driven by PS2802-4 opto-
isolators rated for 24 volts maximum and up to 80 mA/output @ 20°C.
Outputs must be connected in either all sinking or all sourcing mode.
how to connect to an output in current sinking and current sourcing modes, respectively.
N O T E : Power supply connections must always be made to both the Output Common Plus (OP) and
Output Common Minus (OM) pins as shown in

W A R N I N G : Opto-isolated inputs and outputs should not be powered by the user output
power. Doing so would compromise the isolation provided by the opto-isolator.
