Product Overview

The Honeywell TC-PPD011, cataloged under engineering part number 51309241-125, is a dedicated power preservation module designed for the Experion LS and C200/C200E controller series. This Battery Extension Module functions as a critical safeguard for volatile memory (RAM), ensuring that control strategies, configuration data, and system variables are retained during total power loss or supply fluctuations. By extending the hold-up time of the processor's internal memory, the TC-PPD011 prevents the need for manual system reloads and cold starts, thereby significantly reducing the Mean Time to Recovery (MTTR) in industrial automation environments. Its modular integration allows for seamless installation within standard I/O racks, providing a fail-safe energy reservoir for mission-critical logic solvers.

Critical Process Utility and Deployment

The TC-PPD011 is strategically deployed in facilities where data persistence is vital for safety and production continuity. In Remote Oil and Gas Wellheads, where power stability can be inconsistent, this module protects the local controller's configuration during intermittent supply interruptions. Within Continuous Chemical Processing, it ensures that the controller maintains its state during emergency power transitions, allowing for a "warm start" that preserves valve positions and setpoint history. It is also an essential component for Manufacturing Automation systems located in regions prone to grid instability. The durable housing and broad thermal rating make it suitable for non-climate-controlled enclosures, while the modular design allows for rapid hot-swapping during routine maintenance cycles without disturbing the active controller's operations.
