FAQ

Q1: What type of field devices should be used with X20DI9371?
A: It is designed for sink input wiring, so compatible sourcing or PNP field devices should provide the 24VDC input signal.

Q2: How does the configurable input filter improve system reliability?
A: It suppresses short noise pulses and contact bounce. The software delay can be adjusted from 0 to 25 ms for the application.

Q3: Can this module be used for functional safety signals?
A: No. X20DI9371 is a standard digital input module. Safety-related circuits should use dedicated safety-rated I/O modules.

Q4: What should be checked before replacing the module?
A: Confirm the X20DI9371 part number, sink wiring method, 24VDC supply, terminal block, bus module, and input-filter settings.
