User digital input (User.DI) wiring example
User input signal D1 includes a total of 24 points from Pin1~Pin24; users can freely select between
NPN or PNP wiring.
When the power of the controller itself is going to be used for the input signal DI:
 The NPN wiring method is as shown in Figure 7.12 below; please connect DI COM (Pin50) of
User.DI/O (D Sub-50P) to P24V (Pin1) of the DC output, and connect the output signals including
buttons, switches and sensors etc. to DI.

 The PNP wiring method is as shown in Figure 7.13 below; please connect DI COM (Pin50) of
User.DI/O (D Sub-50P) to N24G (Pin2) of the DC output, and connect the output signals including
buttons, switches and sensors etc. to DI.

Note:
The power control box DC output connector already provides the N24G power; please do not connect
the User.DI signal to other powers in order to prevent the signal from not being able to be sent or
causing the DI contact to burn
