Description
Honeywell MC-TAMR04 – Series C temperature/analog input module for Experion PKS C300 systems
The Honeywell MC-TAMR04 belongs to the Series C I/O family used with Experion PKS C300 controllers. It’s typically deployed for temperature and low-level analog measurements—think RTDs (Pt100/Pt1000) and millivolt/thermocouple signals—where stable accuracy, diagnostics, and clean integration into the Honeywell IOTA backplane matter. One thing I appreciate is how it slots into existing Honeywell I/O Termination Assemblies (IOTAs) without fuss, making upgrades and field swaps quick even in running plants.
From my experience, plants use MC-TAMR04 in furnace zones, heat exchangers, and environmental monitoring points where you need reliable temperature feedback and sensor break detection. You might notice that the module follows Honeywell’s consistent Series C footprint and supports the platform’s redundancy and hot-swap practices, which in many cases shortens downtime and keeps loops steady during maintenance.

Key Features
- Series C temperature/analog inputs – Typically supports RTD (Pt100/Pt1000) and low‑level mV/TC measurement for process temperature points.
- 4-channel density – A practical balance for critical loops where signal integrity and redundancy are prioritized.
- Diagnostics and sensor fault handling – Open‑circuit detection and channel health status help maintenance react faster.
- Backplane power via Honeywell IOTA – Clean wiring and no separate power adapters; typically low power draw.
- Hot‑swap behavior within Series C – In most cases, modules can be replaced with minimal disruption, which operators value during turnarounds.
- Fits standard Honeywell cabinets – DIN‑rail/IOTA assembly mounting keeps enclosures tidy and serviceable.
Feedback from a site maintenance lead: “Swapped an MC‑TAMR04 during a short window. The wiring stayed on the IOTA, so the changeover was quicker than expected, and the loop revalidated cleanly.”
