MU-TDOR12 51304443-100 | Honeywell | TDC 3000 Digital Output Relay FTA

Product Overview

The Honeywell MU-TDOR12 (Part Number: 51304443-100) functions as a high-capacity Digital Output Field Termination Assembly (FTA) designed for the Honeywell TDC 3000 ecosystem. This module bridges the gap between low-level controller logic and high-power field devices, enabling the system to drive solenoids, motor starters, and heavy-duty actuators. We supply this unit as 100% Brand New Original equipment to ensure maximum switching reliability and zero-latency response in mission-critical process loops.

Technical Specifications

The MU-TDOR12 integrates 16 independent relay channels within a standard Size B footprint, providing robust physical isolation for discrete control:

Engineering Advantages

• High-Voltage Switching Versatility: This FTA manages both AC and DC loads up to 120Vac/125Vdc. This flexibility eliminates the need for interposing relays when driving standard industrial solenoids or contactors directly from the DCS.

• Physical Galvanic Isolation: The electromechanical relay architecture provides a physical air gap between the field wiring and the sensitive IOP (Input/Output Processor). This barrier protects the system backplane from catastrophic electrical surges and ground loops.

• Robust Overcurrent Protection: Each channel utilizes a 6A Slo-Blo fuse. This specific fuse rating prevents nuisance trips caused by high inrush currents during inductive load activation, while still providing critical protection for the PWA traces and relay contacts.

• Secure Field Connections: Compression terminals facilitate rapid and gas-tight wiring. This connection method resists mechanical loosening in high-vibration environments, ensuring consistent electrical contact over long-term operations.

• Native IOP Integration: The MU-TDOR12 integrates directly with MU-PDOX01 and MU/MC-PDOX02 processors. This native compatibility ensures full diagnostic transparency and seamless mapping within the Honeywell control strategy.

FAQs

• Can the MU-TDOR12 51304443-100 support redundant I/O configurations?

  No, this specific part number (51304443-100) does not support redundancy. It serves as a non-redundant termination board for standard digital output applications.

• What is the significance of the "Non-Conformal Coated" specification?

  This board lacks the extra resin layer used for high-humidity or corrosive (G3) environments. Engineers should install the 51304443-100 in climate-controlled, non-corrosive cabinet environments to ensure maximum service life.

• How does the "Slo-Blo" fuse benefit inductive loads?

  Inductive devices like solenoids draw a momentary current spike upon energization. The 6A Slo-Blo fuse ignores these micro-second peaks but clears the circuit if a sustained overcurrent condition occurs, preventing relay contact welding.

• Is this board a refurbished or surplus unit?

  Absolutely not. We guarantee this MU-TDOR12 as 100% Brand New Original stock. It arrives in factory-sealed packaging with full manufacturer traceability, meeting the highest procurement standards for industrial automation.
