51305907-175 | Honeywell MC-TAMR04 UCN Series Low-Level Analog Input Multiplexer

Product Overview

The Honeywell MC-TAMR04 (Part Number: 51305907-175) serves as a precision-engineered low-level analog input multiplexer within the Universal Control Network (UCN) series. This module streamlines the acquisition of high-fidelity signals from thermocouples and RTDs, facilitating complex data processing for Honeywell TDC 3000 Distributed Control Systems (DCS). We supply this hardware in 100% Brand New and Original factory condition, ensuring your process control environment operates with the absolute highest signal integrity and zero-hour reliability.

Technical Specifications

Engineering Advantages

• Eliminates Signal Drift: Programmable gain and offset features allow technicians to calibrate each channel precisely. This ensures the DCS receives an accurate representation of field variables, even when dealing with micro-volt level thermocouple signals.

• Solves Ground Loop Interference: The MC-TAMR04 utilizes robust electrical isolation between 16-channel increments. This architectural choice prevents ground loops from corrupting low-level data, which is essential in large-scale industrial plants where potential differences exist between grounding points.

• Simplifies Sensor Troubleshooting: Integrated Open Sensor Detection (OTD) instantly identifies broken thermocouples or RTD wiring. This diagnostic capability reduces Mean Time to Repair (MTTR) by pinpointing field-side failures directly at the I/O level.

• Withstands Aggressive Environments: The wide operating spectrum of -40°C to +70°C ensures consistent performance in non-climate-controlled instrument houses. The rugged mechanical design protects internal solid-state components from the thermal stresses typical of heavy manufacturing and chemical processing.

• Flexible Installation: Support for both DIN rail and panel mounting allows engineers to integrate the multiplexer into tight cabinet spaces or legacy racks without requiring specialized mounting hardware.

FAQs

• How many total inputs can the MC-TAMR04 handle? Each individual module manages 16 analog input channels using high-reliability solid-state relays. However, the system architecture supports multiplexing up to 64 inputs by integrating multiple modules in 16-channel increments.

• Is this module compatible with modern Honeywell Experion systems? The MC-TAMR04 primarily targets the TDC 3000 UCN environment. While some migration paths exist, always verify your specific I/O Link or Gateway requirements when attempting to bridge this legacy UCN hardware with newer Experion PKS platforms.

• Does the unit come with a factory warranty and original packaging? Yes. We guarantee that every 51305907-175 unit arrives 100% Brand New in its original Honeywell factory packaging. This ensures the product meets all original USA manufacturing standards and provides a full service life.

• What cable type should I use for the low-level inputs? To maximize the precision of the MC-TAMR04, use high-quality shielded twisted-pair (STP) extension wire specifically rated for your sensor type (e.g., Type K thermocouple wire). This minimizes electromagnetic interference (EMI) and maintains the integrity of the millivolt signals over long distances.
