Honeywell 51309218-125 | MU-TAMR03 | Low Level Analog Input Multiplexer RTD FTA

Product Description

The MU-TAMR03 (51309218-125) is a specialized Low Level Analog Input Multiplexer (LLMux) Field Termination Assembly designed specifically for Resistance Temperature Detector (RTD) inputs. This module serves as the critical physical interface between field-mounted temperature sensors and the Honeywell TDC 3000 or Experion PKS control systems.

Engineered for high-density temperature monitoring, the MU-TAMR03 (51309218-125) supports 16 independent input channels. This specific hardware revision features rugged compression-style terminals, ensuring secure and vibration-resistant physical wire terminations for sensitive low-level signals. Note that this version is non-conformally coated and is intended for use in environments where CE compliance is not a regulatory requirement.
