Honeywell MU-TAOX12 Analog Output Redundancy Board – Experion PKS Series
When an analog output module fails without redundancy protection in a critical process control environment, the consequences can be immediate and severe: uncontrolled valve positions, runaway process variables, emergency shutdowns, and costly production losses measured in thousands of dollars per hour. In petrochemical plants, power generation facilities, and pharmaceutical manufacturing lines, a single point of failure in the output chain is simply not acceptable. The Honeywell MU-TAOX12 51304335-100 Analog Output Redundancy Board exists precisely to eliminate that vulnerability — providing seamless, bumpless switchover that keeps your process running even when the primary output module encounters a fault.
The MU-TAOX12 (part number 51304335-100) is a purpose-engineered redundancy termination board within Honeywell’s Experion PKS (Process Knowledge System) platform — one of the most widely deployed DCS architectures in global heavy industry. Designed to work in tandem with the MC-TAOX12 Analog Output I/O module, this board forms the backbone of a fault-tolerant 4–20 mA output subsystem. Its position in the Experion PKS ecosystem places it at the intersection of field-proven reliability and modern process automation architecture, trusted by engineers across refining, LNG, power, and specialty chemicals worldwide.

Frequently Asked Questions
Q: What is the difference between MU-TAOX12 and MC-TAOX12?
A: The MC-TAOX12 is the active Analog Output I/O module that processes and transmits the 4–20 mA signals. The MU-TAOX12 is the redundancy termination board that provides the physical switching infrastructure to enable hot-standby redundancy between two MC-TAOX12 modules. Both are required for a fully redundant analog output subsystem.
Q: Is the MU-TAOX12 51304335-100 compatible with all Experion PKS versions?
A: The MU-TAOX12 is designed for the Experion PKS platform. Hardware revision compatibility depends on your installed system version. Please provide your system details when submitting an RFQ so our team can confirm compatibility.
Q: Do you supply new, refurbished, or used units?
A: We supply both new (factory-sealed) and professionally refurbished units depending on availability. All units are clearly labeled with their condition, and refurbished units undergo full inspection and testing before shipment.
Q: What is the typical lead time?
A: Lead time varies by stock availability. In-stock items typically ship within 3–5 business days. For sourced items, lead time is typically 2–4 weeks. Contact us for current availability.
Q: Can you provide export documentation for customs clearance?
A: Yes. We provide commercial invoice, packing list, certificate of conformance, and can assist with country-of-origin documentation as required.
