Honeywell TC-IAH061 / TK-IAH061 High Level Analog 6-Input Module
Honeywell TC-IAH061 and TK-IAH061 are high level analog input modules for industrial control systems. Each module provides 6 galvanically isolated channels. It accepts voltage and current signals. Typical inputs are 10 V and 4-20 mA. The module suits precise measurement in process automation. It works well in noisy plant environments. Channel to channel isolation protects your signals. The on-board 249 ohm resistor supports current loops. This module is a solid choice for legacy Honeywell systems. Oiltech Controls supplies tested units worldwide.

Installation Guide
- Mount the module in a compatible Honeywell backplane slot.
- Use the TC-TBNH 20-position terminal block for wiring.
- Keep input wiring away from high power cables.
- Check the 249 ohm resistor for current loop inputs.
- Verify backplane current before power up.
- Allow 80 ms settling time after input changes.
Debugging and Maintenance
- Use open circuit detection to find broken sensors fast.
- Voltage inputs read upscale on open circuit.
- Current inputs read zero scale on open circuit.
- Check noise rejection with a 60 Hz reference signal.
- Recalibrate when temperature drift exceeds expected limits.
- Inspect terminal blocks for tight and clean connections.
