Description

The Emerson FOXBORO P0916PWOC is a high-density 160W DIN-rail power supply engineered for mission-critical industrial automation systems. Designed as part of Emerson’s FOXBORO power solutions portfolio, this module delivers precision 24VDC power to I/O modules, safety systems, and field devices in demanding environments. The FOXBORO P0916PWOC features universal 85-264VAC input with active power factor correction (PFC >0.98), minimizing harmonic distortion while achieving 94% efficiency. Its convection-cooled, fanless design ensures silent operation and eliminates moving parts failures, with reinforced 3000VAC isolation between input/output circuits to prevent ground loops and protect sensitive electronics.

Certified for SIL 2 applications per IEC 61508, the Emerson FOXBORO P0916PWOC incorporates advanced surge protection (6kV/5kA) and built-in redundancy support through parallel operation with OR-ing diodes. The module maintains full 160W output across -25°C to +70°C ambient without derating, using extruded aluminum heatsinks for optimal thermal management. With comprehensive monitoring via PMBus 1.3 protocol, the P0916PWOC provides real-time diagnostics for voltage, current, temperature, and efficiency – enabling predictive maintenance in refinery safety systems, power generation controls, and continuous process applications where power integrity is non-negotiable.

Technical Specifications

Main Features and Advantages

Ultra-Stable Power Delivery: Precision voltage regulation (±0.8%) with<2>

Advanced Diagnostics: Real-time PMBus telemetry monitors 15+ parameters including efficiency, temperature, and load current. Integrated alarm relays provide dry-contact warnings for undervoltage or overtemperature conditions before failures occur.

Extreme Environment Resilience: Fanless IP20-rated enclosure withstands 5g vibration (IEC 60068-2-6) and 95% non-condensing humidity. Aluminum housing with corrosion-resistant coating ensures reliability in chemical processing areas.

Smart Integration: Auto-synchronization with parallel units eliminates output contention. DIN-rail mounting (TS35/7.5/15) with push-in terminals reduces installation time by 50% versus screw connectors. Backward-compatible with legacy FOXBORO FBM chassis.

Application Field

The Emerson FOXBORO P0916PWOC secures power for critical infrastructure across heavy industries. In oil & gas refineries, it energizes emergency shutdown (ESD) valve controllers and fire/gas detection panels. Petrochemical plants deploy it for reactor feed pump VFDs and distributed control cabinets along ethylene cracker units. Power generation facilities rely on its surge immunity for turbine governor controls and exciter fields in peak-load conditions.

Water treatment plants utilize the P0916PWOC for SCADA-controlled pumping stations and UV disinfection systems. Pharmaceutical manufacturers depend on its clean power for aseptic filling line servos and bioreactor control panels. The module’s railway certification (EN 50155) supports signaling systems and rolling stock battery management in transit applications.
