Overview
The Honeywell MC-PSRX04 is a critical component for enhancing system availability within the Experion PKS architecture. This redundant power supply module is engineered to eliminate a single point of failure in the power path, providing uninterrupted power to vital system components like controllers, networks, or I/O modules, thereby maximizing uptime in mission-critical processes.

Key Features & Benefits:

• True Redundancy: Features two independent, isolated power inputs and conversion circuits. If one power supply fails, the other seamlessly takes over the entire load without interruption.

• High Availability: Essential for maintaining continuous operation of safety systems (FSC/Safety Manager), critical controllers, or network equipment, directly supporting plant reliability goals。

• Hot-Swappable Design: Allows for the replacement of a failed power supply module without needing to shut down the connected equipment, facilitating easy maintenance and reducing downtime。

• Comprehensive Diagnostics: Provides status indicators and system alarms for power supply health, input power loss, and module failure, enabling proactive maintenance。

• Robust Design: Built to meet industrial standards for temperature, vibration, and electrical noise。

Technical Specifications:

• Product Code: MC-PSRX04

• Part Number: 51404174-275

• Module Type: Redundant Power Supply Module

• Input Voltage: Typically accepts a range of AC or DC voltages (e.g., 120/240V AC, 24V DC).

• Output Voltage: Provides a stable DC output (e.g., 5V, 24V) suitable for the connected electronics.

• Output Power: Sufficient wattage to power the intended load (e.g., a controller chassis and its I/O modules).

• Redundancy: N+1 redundancy (1+1).

Typical Applications:

• Providing fault-tolerant power to Honeywell Safety Manager PLCs。

• Powering critical C300 Process Controller chassis in an Experion PKS system。

• Supporting redundant network switches or other infrastructure equipment within the control architecture。
