Overview

The Honeywell 51454475-100 is a specialized RAM Charger Module designed for use with the Series 8 C300 controller in Honeywell’s Experion Process Knowledge System (PKS). Its primary function is to maintain volatile memory contents during power interruptions, ensuring that essential control data and configurations are preserved.

Moreover, this module plays a vital role in enhancing system reliability and uptime in mission-critical industrial environments. In addition, its compact single-slot design allows for easy integration into existing C300 controller assemblies without requiring additional space or complex wiring.

With certifications including CE, TUV, UL508, and CSA, the 51454475-100 meets global industrial standards. Therefore, it is widely adopted in industries such as oil & gas, chemical processing, and power generation, where data integrity and system continuity are paramount.

Technical Data

Typical Applications

• Power Loss Protection: Maintains RAM data in C300 controllers during power outages or brownouts.

• Process Automation: Ensures uninterrupted control logic and configuration retention in critical process industries.

• Distributed Control Systems (DCS): Supports high-availability architectures in Honeywell Experion PKS environments.

• System Redundancy: Enhances controller resilience by preserving volatile memory across power cycles.

• Industrial Safety Systems: Used in applications where data loss could compromise safety or compliance.

For instance, in a petrochemical plant, this module ensures that the C300 controller retains its logic and process variables during a sudden power failure. In addition, its seamless integration with Series 8 hardware reduces installation time and minimizes system downtime.

FAQ

Q: Is the 51454475-100 a controller?
