Product Overview

TC‑IAH161 is 16‑channel high‑level isolated analog input module for Honeywell industrial control‑systems. It acquires standard 4‑20 mA and ±10 V signals from field transmitters. Each channel provides galvanic isolation, open‑loop detection and over‑range diagnostics to improve field‑loop reliability. Hot‑swap capable for on‑line module replacement without rack shutdown. Widely deployed in petrochemical, power‑plant and chemical‑process‑control cabinets. Available as refurbished and new‑old‑stock spare parts for DCS‑PLC‑system maintenance.

Application Notes

‑ Install on system rack backplane, pair with TC‑TBCH terminal board. ‑ Configure channel signal‑type via system configuration software. ‑ ESD anti‑static handling required during hot‑swap replacement. ‑ Typical deployment: refinery and thermal‑power‑plant analog‑signal‑acquisition spare‑part stocking.
