Product Overview
The TC-IAH161 (Part Number: TC-IAH161) is a high-density Series C Analog Input module designed for the Honeywell Experion PKS environment. It provides 16 isolated channels capable of interfacing with standard voltage and current signals from field transmitters. Engineered for precision and industrial resilience, the module delivers 16-bit resolution across all input ranges, ensuring high-fidelity data acquisition for critical process loops.

With a 250 ms publish rate, the TC-IAH161 is ideal for standard process monitoring requiring deterministic data updates. Integrated signal conditioning and RFI immunity maintain signal integrity even in electrically noisy industrial environments.

Frequently Asked Questions (FAQ)

Q: Does the TC-IAH161 require an external resistor for current loops?
A: No. The module includes an internal 249 Ω precision resistor for current-to-voltage conversion, simplifying wiring for 0–20 mA or 4–20 mA signals.

Q: Which terminal block is compatible with this module?
A: The TC-IAH161 is designed to work with the TC-TBCH 36-position terminal block for secure field terminations.
