Frequently Asked Questions (FAQ)

Question: How does the module react if a 4...20 mA field loop experiences a physical wire break?

Answer: The specific channel red fault LED illuminates instantly to alert field maintenance technicians.

Question: Can I mix different current ranges such as 0...20 mA and 4...20 mA simultaneously across the channels?

Answer: Yes, users configure each channel independently inside the engineering software environment.

Question: Does the 250 Ohm input impedance require external shunt resistors installed at the terminal block?

Answer: No, the precision 250 Ohm resistors are built internally into the module hardware circuitry.

Question: What operational advantage does the 34 Hz low-pass filter provide?

Answer: It attenuates industrial frequency hum to prevent measurement signal jitter on analog loops.

Question: Why does the 140ACI04000 require 17 input words instead of exactly 16?

Answer: The 17th word contains comprehensive channel diagnostics and hardware status information for the CPU.
