Honeywell TC-IAH061 96978074-A01 Experion Analog Input Module

The Honeywell TC-IAH061 96978074-A01, also cataloged as the TC-IAH061 Analog Input Modules, operates as a dedicated hardware component for high-speed multi-channel field variable acquisition within Experion PKS C200/C300 controller chassis platforms.

Hardware Specifications

Channel-to-Channel Isolation & 4-20 mA HART Loop Protocol Execution

The TC-IAH061 module incorporates internal optical barriers providing full channel-to-channel isolation across all 6 analog input channels. Designed to process differential 4-20 mA HART loop protocol and voltage signals, the hardware suppresses common-mode noise and prevents ground loop currents between field devices. Integrated signal-conditioning circuits execute open-circuit detection while maintaining a 25 ms update rate across all channels and filtering RF interference to less than 2.0% error under 10 V/m field exposure.

Frequently Asked Questions

Q: Does replacing a TC-IAH061 module require disconnecting field wiring from the terminal assembly?

A: No, field wiring lands directly on the 20-position TC-TBNH terminal block, allowing the active TC-IAH061 module to be unseated while field conductors stay attached.

Q: How does the TC-IAH061 handle open circuit conditions on current loops versus voltage inputs?

A: Open circuit detection yields a zero-scale reading for current inputs within 1 second, whereas voltage inputs drive to an upscale reading within 5 seconds.

Q: Can the TC-IAH061 module be hot-swapped during active controller operation?

A: Hot-swapping is supported when installed in compatible backplane racks, subject to site safety rules and cabinet hazardous area classifications.

Field Installation Guidelines

1. Seat the TC-IAH061 module into the designated slot on the chassis rack until the mounting levers snap into the locked position.
2. Align the 20-position TC-TBNH terminal block with the module header pins and press firmly to secure mechanical engagement.
3. Terminate shielded twisted-pair signal cables to the TC-TBNH screw terminals, maintaining proper wire gauge and strip dimensions.
4. Ground all cable drain shields directly to the cabinet enclosure earth ground bar to maintain specified RFI immunity performance.
