Honeywell MC-TAMT03 51309223-175 Analog Input Module

Product Overview

This analog input module interfaces field transmitters with Honeywell’s TDC 3000 control system. It converts standard process signals into digital values for monitoring and control purposes. The MC-TAMT03 51309223-175 provides multiple isolated channels for reliable analog signal acquisition. Its robust design ensures accurate measurement across varied industrial environments. This module plays a vital role in continuous process control and data acquisition applications.

Technical Specifications

The MC-TAMT03 51309223-175 measures 27.9 cm in height, 17.8 cm in depth, and 2.5 cm in width. It weighs approximately 0.8 kg, including all terminal hardware and connectors. This module draws 250 mA from the 24 VDC power supply under normal operating conditions. It features eight differential analog input channels with 14-bit resolution. Each channel accepts standard 4-20 mA signals with a maximum input range of 0 to 50 mA. The module also supports 0-5 VDC and 0-10 VDC voltage inputs through jumper selection. Its conversion time measures 100 ms for scanning all eight channels continuously. The unit provides 1500 VAC optical isolation between field circuits and the backplane. The front panel features a green LED for power status and individual channel activity indicators.

Signal Conditioning and Data Processing

This module applies digital filtering to eliminate noise from field sensor signals. It performs linearization and engineering unit conversion for each input channel independently. The MC-TAMT03 51309223-175 supports both differential and single-ended measurement configurations. Users can configure input ranges and alarm setpoints through the system software. The module also includes open-circuit detection for each analog channel.

Physical and Electrical Parameters

Installation and Wiring Guidelines

Install the MC-TAMT03 51309223-175 into the designated slot within the TDC 3000 chassis. Secure the module firmly using the retaining screws at both ends. Wire each field transmitter to its corresponding input channel with correct polarity. The module automatically initializes and begins signal conversion upon power-up. Configure input parameters through the system configuration software. Monitor channel status through both software and front-panel LED indicators.

Typical Applications

This module monitors temperature sensors, pressure transmitters, and level devices in process plants. It reads flow meters, pH analyzers, and conductivity sensors in continuous operations. The MC-TAMT03 51309223-175 serves refineries, chemical plants, and power generation facilities. Its eight-channel density suits applications requiring multiple analog measurements.
