Frequently Asked Questions (FAQ)

Q: Can the CC-PAIH51 read both 4-20 mA and voltage signals?A: No. It accepts only 4-20 mA current inputs through an internal 200 Ω resistor. For voltage signals, use a different module.
Q: How do I choose between the CC-TAIX51 and CC-TAIX61 IOTA?A: Use CC-TAIX51 for non-redundant applications where losing one module is acceptable. Choose CC-TAIX61 if you need 1:1 redundancy for critical loops. The 12-inch depth provides space for two modules.
Q: Does it support HART digital data?A: Yes. The module passes HART frequency signals to the controller. You can access device diagnostics and second variables through Experion.
Q: What is the typical lead time and shipping method?A: We ship via FedEx, UPS, or DHL express. Stock items usually ship within 24 hours. The module comes with a 12-month warranty.
Q: Any field advice for first-time users?A: When wiring, ensure the transmitter loop has proper polarity. The input is single-ended, so common mode voltage must stay within -6 to +5 V. Also, always install the module in the correct IOTA slot before powering up to avoid ground loops.
