TC-IAH161 | Honeywell High Level Analog Input Module
The TC-IAH161 is a high-performance 16-channel high-level analog input module engineered by Honeywell for advanced industrial control systems. It provides accurate, reliable conversion of voltage and current signals, supporting multi-range inputs across demanding automation environments. Equipped with robust 16-bit resolution and strict signal isolation, this module ensures high precision and operational safety for complex industrial loops.
Signal Inputs and Resolution
The module features 16 isolated analog input points capable of handling multiple voltage ranges, including +/-10.25 V, 0 to 10.25 V, and 0 to 5.125 V, alongside current ranges from 0 to 20.5 mA utilizing internal 249 ohm to 250 ohm resistors. High-precision 16-bit analog-to-digital conversion is delivered uniformly across every configured measurement range to preserve signal fidelity.
Electrical Performance and Immunity
Signal conditioning incorporates a channel bandwidth of 20 Hz at -3 dB and a module publish rate of 250 ms. To maintain data integrity under harsh conditions, the circuitry delivers strong radio frequency interference immunity with less than 2.0% error at 10 V/m across 27 to 1000 MHz.
Isolation and Wiring Configuration
Field connections are managed via a 36-position TC-TBCH terminal block designed for secure physical integration. User-to-system isolation is rigorously tested at 2550 VDC for 1 second, protecting downstream control electronics from high-voltage transients and ground potential shifts.
