MU-TAOX02 51304476-100 TDC 3000 Analog Output Termination Board | Honeywell

Product Overview

The Honeywell MU-TAOX02 (Part Number: 51304476-100) serves as the critical interface between the control system's processor and field-side actuators. This Analog Output Termination Board facilitates the precise distribution of 4-20mA or 0-10V signals to modulating valves, dampers, and variable speed drives. We supply this unit as 100% Brand New Original equipment, ensuring maximum loop integrity and eliminating the risks associated with refurbished or used termination hardware.

Technical Specifications

The MU-TAOX02 features a ruggedized PCB design tailored for the high-availability requirements of Distributed Control Systems (DCS):

Engineering Advantages

• Noise Mitigation: The board architecture incorporates specialized grounding planes and filtering components. These features suppress electromagnetic interference (EMI), ensuring that clean, stable signals reach your final control elements without jitter or drift.

• Streamlined Field Wiring: The MU-TAOX02 organizes field connections through a centralized termination point. This layout reduces cabinet clutter, simplifies multi-core cable management, and speeds up commissioning times during plant turnarounds.

• Redundancy Support: This termination board integrates seamlessly into redundant I/O configurations. It allows dual-processor tracking, ensuring that if one controller fails, the MU-TAOX02 continues to pass control signals to the field without process interruption.

• Compact Footprint: With dimensions of 17.8 cm x 7.8 cm, the board maximizes cabinet rail density. This allows engineers to expand I/O capacity within existing enclosures, avoiding the need for expensive new cabinet installations.

FAQs

• Does this board support both current and voltage outputs?

  Yes. The MU-TAOX02 manages standard industrial analog ranges. Ensure that your associated Analog Output Module (AOM) is configured correctly in the system software to match the field device requirements.

• Can the MU-TAOX02 replace older TAOX-series boards?

  The MU-TAOX02 (51304476-100) serves as a modern replacement for several legacy versions. However, always verify your specific backplane connector style and firmware compatibility with the TDC 3000 or Experion PKS system.

• What are the primary mounting requirements?

  The board snaps directly into standard Honeywell Field Termination Assembly (FTA) mounting channels. We recommend maintaining a 25mm clearance between adjacent boards to ensure adequate airflow and prevent heat buildup in high-density cabinets.

• Is this board conformally coated?

  This specific part number (51304476-100) follows standard industrial coating protocols. For highly corrosive environments containing H2S or chlorine, please contact our technical team to verify the specific G3-level protection ratings.
