Product Overview

The Honeywell MC-TAMR04 (Part Number: 51305907-175) is a Low Level Analog Input (LLAI) Multiplexer Field Termination Assembly (FTA) designed for use in Honeywell TDC 3000 and Experion PKS systems. It interfaces with millivolt-level signals from temperature sensors such as thermocouples and RTDs, enabling accurate temperature measurement in industrial processes.

We supply this unit as 100% brand new and original equipment, ensuring high signal fidelity, proper isolation, and stable operation in sensitive temperature monitoring applications.

Technical Specifications

Engineering Advantages

Precision Millivolt Processing
Designed to handle extremely low-voltage signals with minimal thermal drift, ensuring accurate and stable temperature measurements in high-temperature environments such as boilers and reactors.

Integrated Cold Junction Compensation (CJC)
Built-in temperature sensing compensates for ambient temperature variations at terminal connections, maintaining thermocouple measurement accuracy despite enclosure temperature changes.

Effective Common-Mode Rejection
Advanced filtering reduces electrical noise and ground loop interference, preserving signal integrity in electrically noisy industrial settings.

High-Density Sensor Integration
Supports 16 multiplexed channels, enabling multiple temperature points to be monitored through a single processor interface, optimizing cost and cabinet space.

Conformal Coating Protection
Factory-applied coating protects PCB components from moisture, dust, and corrosive atmospheres, improving reliability in harsh process environments.

FAQs

Does this module support both RTDs and thermocouples?
Yes. It supports both sensor types, but configuration in the I/O processor (and any required jumpers or settings) must match the specific sensor type (e.g., Type K thermocouple, Pt100 RTD).

Is this a brand new or refurbished component?
It is 100% brand new, original, and shipped in factory-sealed anti-static packaging.

Does the MC-TAMR04 require a specific carrier file?
Yes, it is installed in standard Honeywell HPM/APM carrier files. Ensure the rack has adequate space and power for the module’s physical and electrical requirements.

How does multiplexing affect the update rate?
Since multiple channels share a common processing path, scan time is slightly longer than dedicated input modules. However, it remains suitable for typical temperature control and monitoring applications.
