Honeywell TC-IAHI61 Analog Input Module 16-Channel HLAI

Honeywell TC-IAHI61 Analog Input Module 16-Channel HLAIProduct Overview The TC IAHI61 is an authoritative High Level Analog Input (HLAI) module designed for Honeywell Experion PKS and TDC 3000 distributed control systems. This module is a mechanical necessity for high density signal acquisition, featuring 16 independent channels that interface directly with field transmitters and sensors. By converting high level analog signals (voltage and current) into precise digital data, the TC IAHI61 enables

The internal processing firmware performs real-time gap voltage validation against standard -10 VDC targets to ensure the proximity sensors remain biased within their linear calibration range

Operating Environment: 0°C to +60°C

Do not install heat-generating components directly beneath the unit to prevent localized temperature increases that may trigger thermal protection

Ground all field device cable shields at a centralized master grounding termination rail to prevent external noise interference loops
