3.4. Opto-Isolated Outputs (TB202, TB203)
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.
to connect to an output in current sourcing and current sinking 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
