Honeywell 620-0083C Processor Power Module

Product Overview

The Honeywell 620-0083C Processor Power Module is a high-reliability industrial power supply unit designed for use with Honeywell’s 620 Series Distributed Control System (DCS). As an upgraded variant of the standard 620-0083 model, the 620-0083C module incorporates enhanced stability, extended temperature tolerance, and robust fault protection to ensure maximum uptime for mission-critical process control systems.

Engineered to power CPUs and logic control boards in complex automation environments, the 620-0083C plays a central role in providing isolated, regulated DC power to processor modules, ensuring smooth operation across diverse industries such as petrochemicals, power generation, metallurgy, pharmaceuticals, and water treatment.

Key Features

• Regulated, isolated multi-output DC power supply

• Enhanced version of the 620-0083 with improved performance range

• Integrated protection: overvoltage, overcurrent, short-circuit, and thermal shutdown

• High Mean Time Between Failures (MTBF) for mission-critical systems

• Convection-cooled; no moving parts, reducing maintenance needs

• Rack-mountable with optional DIN rail configuration

• Designed for continuous 24/7 industrial operations
