9.3.1 Input Wiring
Note
Input signal wiring may differ by external device types.
PNP Device
If you use the pull-down resistor of the supplied IO box, the wiring is shown below.
Figure 9-5 Input Signal Connecting to PNP Device (Pull-Down Resistor of IO Box Used)
If you use external pull-down resistor, it is recommended to use 1 KΩ pull-down resistor.
Figure 9-6 Input Signal Connecting to PNP Device (External Pull-Down Resistor Used)
NPN Device
If the VCC of NPN device is 12 VDC or 24 VDC, and the pull-up resistor of the supplied IO
box is used.
