Product Overview

The ABB PFEA113-65(Order Code:3BSE050092R65)is a high-performance,redundant power supply module designed for use in ABB’s System 800xA and AC 800M distributed control systems(DCS/PLC),which are widely deployed in power generation,oil&gas,mining,and heavy industrial automation.As part of ABB’s PFEA11x series of fieldbus-compatible power supplies,the PFEA113-65 delivers stable,filtered,and protected 24 V DC power to I/O modules,communication units,and other critical components within an AC 800M controller rack or remote I/O station.Its key role is to ensure uninterrupted operation of safety-critical control logic—even during mains disturbances—by supporting seamless redundancy with a second PFEA113 unit via integrated OR-ing diodes and status signaling.

Engineered for harsh industrial environments,the ABB PFEA113-65 features wide input voltage tolerance(85–264 V AC/100–370 V DC),short-circuit protection,overvoltage clamping,and thermal shutdown,making it resilient against brownouts,surges,and inductive load switching common near large motors or switchgear.The“-65”suffix denotes a specific hardware revision optimized for compatibility with later-generation AC 800M controllers(e.g.,PM86x series)and enhanced diagnostics via the Controller Area Network(CAN)bus used in ABB’s ModuleBus architecture.When installed in pairs,the modules automatically share load and signal“OK/Fail”status to the CPU,enabling predictive maintenance before a single point of failure can compromise system availability.Trusted in thousands of mission-critical plants worldwide—from nuclear turbine controls to LNG liquefaction trains—the ABB PFEA113-65 exemplifies ABB’s commitment to reliability,serviceability,and lifecycle support in industrial automation infrastructure.

Main Features and Advantages

True N+1 Redundancy with Automatic Load Sharing:

Two ABB PFEA113-65 units can be connected in parallel to provide fault-tolerant power.If one fails,the other instantly assumes full load without voltage sag—critical for maintaining I/O integrity during process transients.

Integrated Diagnostics via ModuleBus:

Unlike generic power supplies,the PFEA113-65 reports real-time status(input OK,output OK,overtemp,fan fault if applicable)directly to the AC 800M CPU.Alarms appear in Control Builder M and System 800xA operator stations,enabling proactive replacement.

Wide Universal Input for Global Deployment:

Accepts both AC and DC mains inputs across a broad range,allowing the same module to be used in 110 V AC North American plants,230 V AC European sites,or 125 V DC battery-backed substations—simplifying spares logistics.

Optimized for S800 I/O and High-Density Racks:

Delivers clean,low-noise 24 V DC required by sensitive analog I/O modules(e.g.,AI810,AO810),minimizing measurement drift in temperature or pressure loops.

Hot-Swappable Design:

Can be replaced during live operation when used in redundant configuration,minimizing downtime during maintenance—a key advantage in continuous-process industries.

Application Field

The ABB PFEA113-65 is primarily used in process automation and power plant control systems where controller uptime directly impacts safety,environmental compliance,or revenue.In fossil and renewable power stations,it powers AC 800M racks managing boiler controls,flue gas desulfurization,or balance-of-plant functions.In oil refineries and petrochemical complexes,it supports S800 I/O stations monitoring reactor temperatures,compressor surge control,and emergency shutdown(ESD)logic.

It is also found in mining operations(conveyor and mill control),pulp&paper lines(steam header regulation),and water treatment facilities(pump sequencing).Because the PFEA113-65 is part of ABB’s long-life-cycle product strategy,it remains a standard spare in legacy System 800xA installations commissioned as early as the 2000s—and continues to be specified in modern brownfield upgrades due to backward compatibility.

Installation and Maintenance

Installation Guidelines:

Always install in pairs for critical applications to enable redundancy.

Ensure adequate ventilation(minimum 50 mm clearance above/below).

Use shielded AC input cables with proper grounding to reduce EMI.

Verify polarity and voltage at output terminals before connecting I/O modules.

Maintenance Recommendations:

Monitor“PSU OK”LED and diagnostic alarms in Control Builder M weekly.

Clean dust from ventilation slots annually using dry,non-conductive air.

Replace proactively after 10–12 years of service,even if functional(electrolytic capacitor aging).

During replacement,confirm the new unit matches the exact order code(3BSE050092R65)to avoid firmware or compatibility issues.
