Overview

The Honeywell MC-TAMT03 Low-Level Input Multiplexer Module is engineered to handle sensitive analog signals, particularly from thermocouples and other low-voltage sensors. It supports up to 16 input channels, enabling high-density signal acquisition for distributed control systems such as Honeywell’s TDC3000 and Experion PKS.

Moreover, the module features onboard Cold Junction Compensation (CJC), which enhances measurement accuracy by correcting for ambient temperature variations. In addition, its rugged design and CE, TUV, UL508, and CSA certifications ensure reliable operation in harsh industrial conditions.

This module is widely used in industries such as chemical processing, power generation, and oil refining, where precise temperature control is critical. Therefore, it is a trusted component in high-integrity automation architectures.

Technical Data

Typical Applications

• Thermocouple Signal Acquisition: Captures low-level analog signals from temperature sensors with high precision.

• Distributed Control Systems (DCS): Integrates seamlessly into Honeywell’s UCN-based platforms for centralized monitoring.

• Process Automation: Used in chemical plants, refineries, and power stations for temperature control and diagnostics.

• High-Density Input Configurations: Supports up to 16 channels, reducing hardware footprint in control cabinets.

• Cold Junction Compensation: Ensures accurate readings by correcting for ambient temperature effects.

For instance, in a steam turbine control system, this module collects temperature data from multiple thermocouples to monitor bearing and casing temperatures. In addition, its compact design allows easy installation in space-constrained environments.
