Product Overview

The Honeywell TK-PPD011 operates as a high-integrity Battery Extension Module (BEM) engineered for the Experion PKS C200 controller ecosystem. This hardware serves as a dedicated energy bridge, delivering immediate auxiliary backup power to volatile controller memory during sudden primary power blackouts. By maintaining this critical voltage loop, the module prevents the catastrophic erasure of the controller database, active configuration parameters, and running process control logic. We stock this item exclusively as a 100% brand new, factory-original unit to ensure continuous field protection and clean, predictable control system recoveries.

Engineering Advantages

Total power loss in a process facility introduces severe financial risks if controllers lose their active run-time parameters and memory states. The TK-PPD011 eliminates these risks by keeping the C200 volatile RAM energized the instant the primary power grid drops. The module draws a low 112 mA from the 5 VDC rail and 36 mA from the 24 VDC rail during standby, prioritizing minimal thermal output within the enclosure. During a complete power failure, the internal power circuit manages the battery discharge path effectively to maintain critical configuration data for up to 12 hours. This extended backup window gives field crews sufficient time to restore the main electrical grid without requiring tedious, manual system re-flashes.

The single-slot mechanical form factor enables direct, tool-free sliding insertion into any open standard slot within a Series A chassis backplane. This interface design routes all power requirements directly through the heavy-duty backplane connectors, eliminating the clutter of loose external wiring and vulnerable terminal connections that frequently fail under industrial vibration. Furthermore, the firmware interacts continuously with Honeywell Experion System Management tools. This native background link allows the host software to perform real-time diagnostic checks on battery charge capacity, remaining shelf life, and circuit path health, alerting maintenance teams via the operator console long before a critical battery depletion event occurs.

FAQs

  • Can the TK-PPD011 module undergo hot-swapping while the C200 controller remains live?

    Yes. The Series A chassis architecture allows field technicians to slide the TK-PPD011 memory backup module into or out of its designated slot under live power conditions. This action does not disturb active C200 controller processing or interrupt concurrent communications on the backplane bus.

  • What specific factors reduce the standard 12-hour data retention window during a plant blackout?

    The 12-hour retention capacity represents an optimal threshold based on a fully charged battery assembly at a standard ambient temperature. High operating temperatures exceeding 40 Degrees Celsius, coupled with dense memory-load allocations on the companion C200 processor, accelerate internal battery cell depletion and shorten the overall backup duration.

  • Does this module require external field power wiring to charge the backup batteries?

    No. The TK-PPD011 draws its internal battery-charging power directly from the 24 VDC rail built into the standard Series A chassis backplane. The module automatically regulates its own charging cycle during normal plant operations, eliminating the need for separate external power loops or dedicated charging stations.
