Honeywell TC-IAH161 Analog Input Module – TotalPlant Solution (TPS) Series
Imagine a critical refinery distillation column losing its temperature feedback signal mid-operation — operators fly blind, safety interlocks fail to respond, and an unplanned shutdown costs tens of thousands of dollars per hour. The Honeywell TC-IAH161 Analog Input Module is the precision front-end component that prevents exactly this scenario. By converting field-level analog signals into reliable digital data streams for the TPS DCS controller, it forms the sensory backbone of your entire process control architecture. Without it, your control system is deaf to the plant.
Within the Honeywell TotalPlant Solution ecosystem, the TC-IAH161 occupies a foundational role as a high-density analog input card engineered for demanding continuous-process environments. TPS remains one of the most widely deployed legacy DCS platforms across global refining, petrochemical, and power generation facilities, and the TC-IAH161 continues to be a mission-critical spare and replacement component for thousands of operating plants worldwide. Its proven field reliability and seamless backward compatibility make it irreplaceable for facilities committed to long-term TPS platform stability.

Frequently Asked Questions
- Q: Is the TC-IAH161 still manufactured by Honeywell?
- A: The TC-IAH161 is part of the legacy TPS/TDC 3000 platform. Honeywell has transitioned to newer DCS architectures, but this module remains available through the industrial aftermarket. Konmask.com specializes in sourcing these legacy components.
- Q: Can I use TC-IAH161 as a direct replacement for a failed module in my TPS system?
- A: In most cases, yes — the TC-IAH161 is a slot-compatible replacement within TPS I/O cabinets. We recommend confirming your cabinet revision and I/O bus version with our technical team before ordering.
- Q: What condition are the modules in?
- A: We stock a mix of new surplus and tested used units. Condition is clearly specified in your quotation. All units pass our inspection process before shipment.
- Q: Do you provide a warranty?
- A: Yes. We offer a standard 90-day warranty against DOA (Dead on Arrival) and functional defects. Extended warranty options are available — please inquire.
- Q: Can you ship to my country?
- A: We ship globally. We handle export documentation and can arrange DDP (Delivered Duty Paid) terms for most destinations. Contact us with your country for a shipping quote.
