Overview

The Honeywell 51304335-225 MU/MC-TAOX52 Analog Output Redundancy Module is engineered to provide reliable analog signal output with built-in redundancy. It connects Distributed Control Systems (DCS) to field devices such as actuators and control valves, transmitting 4–20 mA signals with precision and stability.

Moreover, this module supports Honeywell’s Universal Control Network (UCN), making it compatible with legacy TDC3000 systems and modern Experion PKS platforms. In addition, its conformal coating and CE, TUV, UL508, and CSA certifications ensure safe operation in hazardous and high-demand environments.

With automatic failover capabilities, the MU/MC-TAOX52 minimizes downtime by switching to a healthy backup channel upon primary output failure. Therefore, it is widely used in industries such as oil & gas, chemical processing, and power generation, where analog output reliability is mission-critical.

Technical Data

Typical Applications

• Redundant Analog Output Channels: Ensures uninterrupted control signal delivery to field devices in case of primary output failure.

• Process Control Systems: Used in Honeywell DCS platforms for precise analog signal transmission to actuators and valves.

• Hazardous Locations: Nonincendive design supports safe operation in Division 2 classified areas.

• Industrial Automation Networks: Facilitates analog output integration across legacy and modern Honeywell systems.

• Safety-Critical Operations: Maintains control integrity in emergency shutdown and interlock systems.

For instance, in a refinery’s control room, this module ensures that analog signals controlling valve positions remain stable even if one output channel fails. In addition, its compatibility with both TDC3000 and Experion PKS simplifies upgrades and system expansions.
