Features:

  • Specifically designed for terminating field wiring from 120 Vac digital devices such as limit switches, push buttons, proximity sensors, and other discrete field contacts to the Honeywell Process Manager system.
  • The conformal coating protects the FTA against moisture, dust, chemical vapors, and corrosive atmospheres, ensuring reliable operation in demanding industrial applications like chemical plants,refineries,and offshore platforms.
  • Compression terminals provide secure, vibration-resistant connections without special tools. CE compliance (part number -175) meets European regulatory standards,with non-CE version (-150) available for other regions.
The MC-TDIA12-51304439-175 is purpose-built for terminating 120 Vac digital input signals from field devices to Honeywell's High-Performance Process Manager control system. This FTA serves as the critical interface between field-mounted devices like limit switches, push buttons, selector switches, and proximity sensors and the controller's digital input modules. The 120 Vac voltage level is common in industrial facilities, particularly in North America, where existing field wiring infrastructure often uses 120 Vac for discrete signals.

The MC-TDIA12-51304439-175 features a conformal coating that significantly enhances its reliability in challenging industrial environments. Conformal coating is a thin, protective layer applied to the printed circuit board that shields the electronic components from moisture, dust, chemical vapors, salt spray, and other contaminants that are common in chemical plants, refineries, wastewater treatment facilities, and offshore platforms.

The MC-TDIA12-51304439-175 utilizes compression terminals for field wiring connections, offering several advantages over traditional screw terminals. Compression terminals create a gas-tight connection by compressing the wire between two metal surfaces, which maintains consistent contact pressure even under vibration from nearby rotating machinery. Unlike screw terminals that can loosen over time due to thermal cycling or mechanical vibration, compression terminals provide a maintenance-free connection. Installation requires no special tools—simply insert the stripped wire and tighten the compression mechanism—reducing installation time and eliminating the risk of over-torque damage.

The MC-TDIA12-51304439-175 HONEYWELL Digital Input Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Petrochemical & Refining: Used to monitor high-voltage switch statuses (such as valve limit switches and explosion-proof switches) in large-scale process plants.
  • Power & Utilities: Deployed in power generation plants and substations to receive breaker statuses and relay trip signals from 120VAC control loops.
  • Chemical & Pharmaceutical: Responsible for tracking the safety interlock statuses of reactors, mixers, and other critical process equipment.
  • Heavy Industry & Material Handling: Applied in steel mills or mining operations to manage running feedback from high-power motors on large conveyors and blowers.
  • High-Voltage Galvanic Isolation: Features 32 independent 120 VAC isolated input channels, effectively blocking field surges and electrical noise from entering the DCS core to protect internal electronics.
  • Redundant High Availability: Supports redundant configurations, enabling a seamless switchover to the backup channel if the primary line or module fails, ensuring zero loss of process data.
  • Environmental Resilience: The "MC" prefix indicates standard Conformal Coating on the PCB, shielding the components against humidity, salt spray, and corrosive chemical gases to maximize Mean Time Between Failures (MTBF).
  • Wiring & Space Efficiency: Utilizes high-density compression terminals, significantly reducing the wiring footprint inside control cabinets while simplifying maintenance and replacement procedures.
  • Valve Position Feedback Monitoring: Feeds the "Fully Open / Fully Closed" limit switch signals (typically 120VAC) from pneumatic or electric valves in remote pipelines or tank farms into the Experion PKS or TDC 3000 system.
  • Motor Control Center (MCC) Feedback: Connects directly to the auxiliary contacts of motor starters to provide operators with real-time "Running / Stopped / Tripped" status feedback for large industrial pumps and fans.
  • Safety Interlock & Alarm Triggering: Captures trip signals from field pressure switches, level switches, or temperature switches, instantly triggering control system interlocks when parameters exceed safe thresholds.
