Product Description

The 51130481-100 (MC-TAMR03) is a high-density Remote Termination Assembly (RTA) designed for the Honeywell TDC 3000 and Experion PKS control systems. This module provides a specialized interface for low-level field signals, offering precise conditioning for Resistance Temperature Detectors (RTD) and a wide array of industrial thermocouples.

Built for the rigors of heavy industrial processing, the 51130481-100 ensures accurate data acquisition by utilizing high-impedance inputs that minimize signal degradation over long cable runs. Each channel is equipped with an independent recorder output, allowing for parallel monitoring without disrupting the primary control loop. Its robust protection circuitry and FCC-compliant shielding make it an essential component for stable temperature management in refineries, power plants, and chemical facilities.
