12 Digital input module XN-322-20DI-ND
The XN-322-20DI-ND digital input module features 20 inputs that are pulled
up to +24 V with a pull-up resistor and relay a logic level of "0" at this voltage.
If an input is pulled down to GND, a signal state of "1" will be relayed for that
input instead. The module features input filters designed to suppress
glitches on the corresponding signal cables.
