Holleywell TK-PPD011 51309241-175 Replacement for Experion PKS

Product Overview

Holleywell TK-PPD011 51309241-175 Replacement for Experion PKS: Seamless Transition from Legacy DCS Power Protection

When your Honeywell Experion PKS or TPS distributed control system relies on a battery backup extension module to maintain controller uptime during power interruptions, the TK-PPD011 (part number 51309241-175) is a critical component in your power protection architecture. As original Honeywell units age, reach end-of-life, or become difficult to source, the Holleywell TK-PPD011 51309241-175 offers a proven, specification-matched replacement that allows your engineering team to execute a smooth migration without redesigning the power subsystem or modifying existing cabinet layouts.

This module is engineered to slot directly into the same mounting position as the original Honeywell 51309241-175, maintaining physical compatibility with standard Experion PKS C200, C300, and legacy TPS node cabinets. The battery extension function — providing sustained backup power to the controller chassis during mains failure — is preserved with equivalent charge/discharge characteristics, ensuring your process does not experience unexpected shutdowns during grid instability or planned maintenance windows.

Seamless Upgrade Solutions

A battery backup extension module replacement rarely happens in isolation. In most Experion PKS and TPS retrofit projects, the TK-PPD011 51309241-175 is replaced alongside a broader power and controller modernization effort. During site surveys, engineers frequently identify that the adjacent Honeywell CC-PAIM01 analog input module or the CC-PDOB01 digital output module also shows signs of wear, making it practical to address the entire I/O cluster in a single maintenance window rather than scheduling multiple outages.

On the power distribution side, the 51309241-175 works in conjunction with the Honeywell 51309276-175 power supply module, which feeds the controller chassis. If the power supply is also approaching end-of-life, sourcing a compatible replacement simultaneously reduces the risk of a secondary failure shortly after the battery module swap. Similarly, the CC-TCF901 controller firewall module and the C300 controller module itself are common co-replacement items when a site is executing a full Experion PKS node refresh.

For sites migrating from legacy TPS to Experion PKS, the transition often involves updating the FTA (Field Termination Assembly) wiring infrastructure. The 51401457-100 FTA and associated MC-TAIH02 termination assemblies are frequently ordered alongside the TK-PPD011 to ensure the field wiring side of the upgrade is completed in the same project phase. This approach eliminates the need for a second field team mobilization and reduces total project cost.

Communication infrastructure upgrades are another common parallel workstream. When the Experion PKS node is being refreshed, the ENET-2 Ethernet interface module and the associated FTE (Fault Tolerant Ethernet) switch infrastructure are often reviewed. Ensuring the replacement battery module is installed before any network reconfiguration work begins is standard practice, as it guarantees the controller remains protected during the communication cutover period.

Finally, for sites that use Honeywell’s Universal I/O (UIO) architecture, the CC-UAIH01 universal analog input module and CC-UAOH01 universal analog output module are frequently part of the same modernization BOM. Coordinating the TK-PPD011 replacement with UIO module upgrades allows the site to consolidate commissioning activities and reduce total downtime exposure.

Retrofit Guidance FAQ

Q: Does replacing the TK-PPD011 require any changes to the Experion PKS controller program?
A: No. The TK-PPD011 51309241-175 is a hardware-level power protection module. It does not interact with the application logic layer of the C200 or C300 controller. No Control Builder modifications, function block changes, or download operations are required after installation.

Q: Is rewiring necessary when swapping from the original Honeywell 51309241-175 to the Holleywell unit?
A: No rewiring is required. The Holleywell TK-PPD011 uses the same connector pinout as the original Honeywell module. The existing field wiring and internal cabinet harness can be reused without modification.

Q: What communication protocols does this module use?
A: The TK-PPD011 communicates via the internal Experion PKS backplane bus for status signaling. It does not use Modbus, PROFIBUS, or any external fieldbus protocol. No protocol configuration is needed during replacement.

Q: Will the module fit in the existing cabinet without physical modification?
A: Yes. The Holleywell TK-PPD011 maintains the same physical dimensions and mounting interface as the original 51309241-175. No cabinet cutouts, bracket modifications, or DIN rail adjustments are required.

Q: How should the replacement be commissioned on-site?
A: After physical installation, verify the battery charge indicator status via the Experion PKS Station display. Allow a full charge cycle (typically 8–12 hours) before returning the node to normal operation. No special commissioning tools or Honeywell-specific software are required beyond standard Experion PKS operator station access.

Q: Can this module be used as a spare part held in inventory?
A: Yes. The TK-PPD011 51309241-175 is suitable for long-term spare parts inventory. Store in a dry environment at 15–30°C. The 12-month warranty from TOPNLMS begins from the date of shipment, not the date of installation.

Warranty Assurance

Every Holleywell TK-PPD011 51309241-175 shipped by TOPNLMS is covered by a 12-month warranty from the date of shipment. Prior to dispatch, each unit undergoes functional verification testing to confirm battery interface integrity, connector condition, and module identification. Units that do not pass inspection are not shipped.

In the event of a warranty claim, TOPNLMS provides replacement support with priority processing for customers experiencing active production impact. Our after-sales response target is within 24 hours of claim submission. Replacement units are dispatched from our Xiamen warehouse, with express international shipping available to minimize site downtime.

Procurement documentation including test reports, packing lists, and commercial invoices is provided with every order to support your site’s incoming inspection and asset management processes. For projects requiring batch procurement of multiple units for spare parts programs, volume pricing and consolidated shipping are available upon request.
