Honeywell 51304335-225 MU/MC-TAOX52 Analog Output Field Termination Assembly
The Honeywell 51304335-225 MU/MC-TAOX52 is a redundant Analog Output Field Termination Assembly (FTA) designed for Honeywell Distributed Control Systems (DCS). It provides signal termination and conditioning for 4-20 mA analog output channels, driving field actuators and control valves. Featuring automatic failover protection, the assembly switches output routing to a healthy redundant channel upon primary channel failure to preserve continuous loop control.
Signal Routing and System Compatibility
The assembly integrates with Honeywell's Universal Control Network (UCN) architecture, supporting deployment across TDC3000 legacy control systems and Experion PKS platforms. It routes output commands directly to final control elements while limiting short-circuit current to 50 mA, shielding upstream control hardware and connected field devices from electrical faults.
Environmental Protection and Hazardous Area Rating
Constructed with conformal coating on circuit assemblies, the 51304335-225 resists atmospheric contaminants and moisture in industrial control environments. Its nonincendive design meets requirements for Class I, Division 2 hazardous location installations, ensuring safe signal distribution in classified process areas.
