51309218-175 MC-TAMR03 Honeywell RTD Multiplexer FTA Honeywell

Product Overview

The Honeywell MC-TAMR03 (Part Number 51309218-175) is a low-level analog input multiplexer Field Termination Assembly designed for RTD temperature inputs in Honeywell TDC 3000 and Experion PKS systems. It consolidates multiple RTD signals into a single IOP interface for efficient data acquisition in process control applications.

• Input Channels: 16 RTD channels
• Input Type: RTD (low-level analog)
• Terminal Type: Compression terminals
• Interface: Single IOP connection
• Operating Temperature: -40°C to +70°C
• Compatibility: Honeywell TDC 3000 / Experion PKS LLMUX IOP

This FTA provides high-integrity signal conditioning for precise temperature monitoring in industrial environments.

FAQ

• What sensor types does MC-TAMR03 support? RTD sensors only (not thermocouples).
• Is redundancy supported? No, this is a non-redundant FTA.
• What is the mounting style? Standard FTA mounting size B.

Installation Guide

1. Power down the associated IOP before installation.
2. Mount the FTA in the designated I/O cabinet using the standard mounting hardware.
3. Connect field RTD wiring to the compression terminals following the channel polarity markings.
4. Connect the IOP interface cable securely.
5. Restore power and verify channel status in the control system.

Selection Tips

• Choose MC-TAMR03 when your application requires dedicated RTD multiplexing with up to 16 channels.
• Pair with the corresponding LLMUX IOP for full temperature input functionality.
• For thermocouple applications, select the MC-TAMT03 instead.
