Product Description

Overview

The Honeywell MC-PSRX04 (Part Number: 51404174-275) is a high-reliability Redundant Power Supply Module designed for critical process control systems, including Honeywell Experion PKS and TDC 3000 platforms. Engineered for harsh industrial environments, this module delivers continuous 24 VDC power to system processors, I/O modules, and communication hardware while maintaining uninterrupted operation in redundant configurations.

Key Features and Functions

• Redundant Operation: Works in tandem with a companion unit to provide seamless failover if a module loses input power.

• Hot-Swappable Design: Can be replaced without shutting down the system, ensuring continuous process control.

• Status Indicators: Front-panel LEDs indicate Power OK, Input Fault, and Over-temperature conditions.

• Power Conditioning: Maintains tight voltage regulation and includes surge and EMI protection to safeguard sensitive electronics.

• Thermal Management: Convection cooling and thermal shutdown protect the module and backplane from overheating.

• System Integration: Communicates operational status to Experion or HPM controllers, enabling real-time monitoring of power faults.

Technical Specifications

Applications

Ideal for high-availability industrial control systems, the MC-PSRX04 is used in oil refineries, chemical plants, and pharmaceutical facilities. Its redundant operation ensures continuous power to critical modules, preventing unexpected downtime and protecting sensitive control electronics.
