The Honeywell TC-IAH161 is a 16-channel High Level Analog Input Module for the Honeywell Series C I/O platform. The TC-IAH161 accepts multiple industry-standard analog signal types, including 0–20 mA, 4–20 mA, ±10 V, 0–10 V, 1–5 V, and 0–5 V, allowing the module to interface with a wide variety of transmitters, sensors, and field instruments. Each input channel can be individually configured to match the connected device, providing flexible integration within industrial process control systems.
The TC-IAH161 utilizes 16-bit analog-to-digital conversion to provide high-resolution measurement of process variables. According to the datasheet, all sixteen channels are scanned with a 25 ms module update period, enabling fast acquisition of analog signals while maintaining measurement accuracy. The module is intended for continuous monitoring of process parameters such as pressure, temperature, flow, level, and other analog measurements used by Honeywell control systems.

Technical notes
The TC-IAH161 provides 2550 VDC user-to-system isolation, with each module 100% tested for one second. This isolation separates field wiring from the system electronics, improving protection against electrical disturbances and supporting reliable signal acquisition in industrial environments. The module connects to field devices through the Honeywell TC-TBNH terminal block, providing a standardized wiring interface for installation and maintenance.
