The Honeywell TK-PPD011 functions as the critical auxiliary power reservoir for the Experion PKS C200 controller ecosystem. This 100% Brand New and Original Battery Extension Module (BEM) safeguards volatile memory during primary power fluctuations or total facility outages. By delivering a stable backup voltage, the TK-PPD011 prevents the loss of essential control programs, runtime databases, and custom configuration setpoints. It acts as a primary insurance policy against system volatility, eliminating the need for time-consuming and expensive manual reloads from engineering workstations following a power event.

Deterministic Memory Safeguarding: The TK-PPD011 maintains a continuous charge to provide instant voltage transition during power loss. This ensures the C200 processor retains its entire RAM-based database, including PID tuning parameters and sequencing logic, allowing for an immediate "warm start" once primary power returns.
Integrated Health Monitoring: Onboard intelligence tracks battery charge cycles and overall health. The module reports these diagnostics directly to the Experion PKS system, enabling predictive maintenance alerts that notify operators before the backup capacity drops below safety thresholds.
Seamless Series-A Integration: The module utilizes the standard Honeywell Series-A form factor. It plugs directly into the controller chassis backplane, drawing power for charging during normal operation and requiring no external wiring for basic memory backup functions.
Industrial Thermal Resilience: Designed to match the C200 processor's environmental ratings, the TK-PPD011 operates reliably from -20°C to +60°C. This wide thermal window prevents premature battery degradation in the high-temperature environments often found in centralized control cabinets.
What is the difference between part number 51309241-175 and 51204142-100?
51309241-175 is the top-level assembly part number for the TK-PPD011 module. 51204142-100 refers to the specific engineering number of the base printed wire assembly (PWA) contained within the module housing.
How often should I replace the battery within the TK-PPD011?
While the module monitors health, we recommend a proactive replacement cycle every 2 to 3 years depending on the ambient temperature of your control room. Higher temperatures accelerate the chemical aging of the backup cells.
Does this module support hot-swapping?
Yes, you can replace the TK-PPD011 while the C200 controller is powered by the primary supply. The controller will rely on its internal capacitors for a very brief window, but we recommend performing the swap while the system is energized to ensure no memory loss occurs.
What determines the actual 12-hour backup duration?
The 12-hour rating represents a typical load. The actual retention time depends on the total memory usage of the C200 processor and the age of the battery cells. High-memory utilization strategies will deplete the backup reservoir faster.
