Alternatively, you can wire a relay to a non-isolated DO (
Figure 3-12
). In that case, you must use the
non-isolated GND and provide 24V to power the relay. To attach a wire, insert it into the connector
and tighten the adjacent screw to secure it. The NO and COM wires go to your external circuit or
device.
