Description

The Honeywell 51309218-175 is a Low Level Analog Multiplexer Field Termination Assembly (FTA) engineered for signal multiplexing within legacy Honeywell FSC and IOP control architectures. As a component of the MC-TAMR03 Rev. E/B series, this unit provides the necessary interface for routing RTD and low-level analog signals from field instrumentation to the control system input processing layers. Please note that this specific model utilizes electromechanical relay switching and has been functionally superseded by the 51305907-175, which utilizes solid-state technology to mitigate relay degradation issues common in high-cycle applications.

Features

  • Designed for integration with Honeywell legacy IOP and FSC systems.
  • Supports multiplexing of RTD and millivolt-level analog inputs.
  • Electromechanical relay-based channel selection architecture.
  • Passive field termination design requiring no internal power supply.
  • Standardized interface for process industry instrumentation loops.

Applications

This FTA is primarily utilized in legacy distributed control system (DCS) environments, including power generation facilities, chemical refineries, and heavy process manufacturing plants where critical low-level analog signal acquisition is required.

Technical Specifications

Model 51309218-175
Brand Honeywell
Module Type Low Level Analog Mux FTA
System Compatibility MC-TAMR03 Rev. E/B
Switching Method Electromechanical Relay
Operating Temperature 0 to 60 deg C

Installation Guidelines

  • Ensure the control system is powered down before installing or removing the FTA from the cabinet.
  • Verify that all field wiring is properly terminated to the designated screw terminals to prevent signal noise or intermittent contact.
  • Maintain proper grounding practices for shielded cables to minimize electromagnetic interference (EMI) on low-level analog signals.
  • Ensure the installation environment is within the specified 0 to 60 deg C temperature range to prevent premature relay wear.
  • Handle with care to avoid damage to the electromechanical relay components.

FAQ

Is the 51309218-175 still the current standard for this application?

No, the 51309218-175 has been superseded by the 51305907-175. The newer model utilizes solid-state switching to eliminate the mechanical wear associated with the relay-based design of the 51309218-175.

Does this module require external power?

No, this is a passive field termination assembly and does not require an internal power supply for its operation.
