Product Overview

The Honeywell CC-SCMB02 (Part Number 51199932-200) is a specialized memory preservation unit engineered for the C300 controller series within the Experion PKS architecture. This RAM Charger Assembly serves as a critical safeguard against data volatility, ensuring that vital process parameters, configuration settings, and runtime variables remain intact during primary power loss. By maintaining a regulated 12 VDC supply to the controller's volatile memory banks, the CC-SCMB02 facilitates a rapid and seamless system recovery. This hardware is essential for preventing cold starts and the associated manual reconfiguration downtime, making it a cornerstone for high-availability Distributed Control System (DCS) nodes.

Operational Use Cases and Industrial Deployment

The CC-SCMB02 is a vital asset for facility operators who prioritize data integrity and continuous uptime in mission-critical environments. Its robust design allows for installation in decentralized cabinets across various heavy industries.

• Critical Process Continuity: Preventing the loss of volatile PID tuning constants and batch recipes during transient power dips or electrical maintenance.

• Rapid System Recommissioning: Reducing Mean Time to Recovery (MTTR) by allowing the C300 controller to resume operation from its last known state without requiring a full database download.

• Remote Substation Automation: Utilizing the RS-485 interface to integrate memory health diagnostics into a centralized management platform for geographically dispersed I/O clusters.

• Extreme Climate Operations: Reliable deployment in unconditioned enclosures within the oil and gas or mining sectors, thanks to its wide-spectrum thermal resilience.

• Legacy System Support: Bridging memory management requirements for both modern Experion PKS setups and legacy TDC 3000 UCM environments.
