25mA Sinking Optoisolated Outputs (LSNK)
Description
The 25mA sinking option, referred to as lower power sinking (LSNK), are capable of sinking up to 25mA per output.
The voltage range for the outputs is 5-24 VDC. These outputs should not be used to drive inductive loads directly.

Wiring the 25mA Sinking Outputs
When wiring the 25mA sinking outputs, the load is wired in the same fashion as the 4mA sinking outputs: The
output power supply will be connected to Output PWR (labeled OPnB) and the power supply return will be
connected to Output GND (labeled OPnA), where n denotes 0 or 1 referring to Bank 0 and Bank 1 respectively.
Note that the load is wired between Output PWR and DO. The wiring diagram for Bank 0 is shown in Figure 3.8 and
Bank 1 in Figure 3.9. Refer to Pin-outs in the Appendix for pin-out information.
