Digital Input (DI)
The digital input is used for monitoring two external events via an external voltage source. When the voltage
level on digital input pins changes from high voltage to low voltage, the DI function will be triggered. Table
2.5 is shown a detail specification of the digital input.

10~30VDC
Normal Status (inactive trigger states)
Nominal input voltage
24VDC
Max. input voltage
