For some applications a digital output can be provided based on the application. Two opto-isolated outputs are available from the SCU5 controller. These outputs are available on a 4-pin M12 female pin connector. A standard M12 4-pin A coded male connector or a pre-wired M12 cable can be used for the connection. The pin functions for the connector are shown in the table below.

1-BR/RD VDD 2-WH OUT2 3-BL/GN GND 4-BK OUT1 The outputs can be used as NPN normally closed output by providing a VDD (5 - 24 VDC) and GND from a PLC and the signal through the two outputs OUT1 and OUT2. A typical circuit for the output is shown below:

When the respective output signal is enabled then that signal would go low. And normally the signal would be high if wired as shown in the schematic on the left. Note that the outputs are normally closed. If wiring a relay, wire to the NC side of the circuit so that the appropriate output from the relay is provided to the device.
