Expert Questions & Answers
Q: Can I mix voltage and current signals on the same FR-A0400M module?
A: Yes, you can. Each of the four channels can be individually set for either 0-10V or 0-20mA input.
Q: What is the best practice for wiring to avoid signal noise?
A: Always use twisted-pair shielded cables. Connect the shield to ground at the PLC end only, not at the sensor.
Q: My sensor outputs 4-20mA. Is the FR-A0400M module compatible?
A: Absolutely. The 0-20mA range perfectly covers the standard 4-20mA industrial signal.
Q: I see reading fluctuations. What could be the cause?
A: First, check for loose connections at the terminal block. Then, ensure the sensor’s power supply is stable and not shared with noisy devices like motors.
