Compatible Replacement & Equivalent Models
The following modules are functionally equivalent or directly compatible replacements for the TC-PRR021. Always verify firmware revision and backplane compatibility before substitution:
- TC-PRR021 (51309288-225) — Original OEM module (this listing)
- TC-PRR021 (51309288-150) — Earlier revision; functionally equivalent in most C200 applications
- TC-CCR014 — C200 Controller Redundancy Module (paired use with TC-PRR021)
- TC-CCR016 — C300 Controller Redundancy Module (next-generation equivalent)
- 51309288-200 — Alternate suffix variant; confirm with Honeywell BOM before use
- CC-PCF901 — Experion C300 Redundancy Cable (required accessory for redundant pairs)
Note: Cross-referencing by part number suffix is recommended. Contact support@konmask.com for compatibility verification.
Why Choose the Original Model
- Guaranteed OEM Compatibility: Factory-tested to Honeywell’s exact firmware and backplane specifications — no integration risk.
- Bumpless Failover: Hot-standby architecture ensures zero-interruption switchover; critical for continuous process industries.
- Long Service Life: Designed for 24/7 industrial environments with proven MTBF in refinery, chemical, and power generation applications.
- Full Honeywell Ecosystem Support: Fully supported by Experion PKS configuration tools, diagnostics, and firmware update utilities.
- Traceable Provenance: Konmask sources from authorized channels with full traceability documentation available on request.
Typical Applications
- Oil & Gas — upstream/downstream DCS controller redundancy
- Petrochemical & Refinery — continuous process control with SIL-rated redundancy requirements
- Power Generation — turbine and boiler control system backup
- Pharmaceutical — batch process control with FDA-compliant redundancy architecture
- Pulp & Paper / Mining — high-availability controller configurations
- Water & Wastewater Treatment — SCADA-integrated redundant control loops
System Compatibility
The TC-PRR021 is validated for use in the following Honeywell system configurations:
- Experion PKS R310 and above (C200/C300 controller chassis)
- TDC 3000 — with appropriate migration kit
- PlantScape — legacy installations (verify revision compatibility)
- Safety Manager — not directly compatible; consult Honeywell FSE
Backplane slot position and firmware revision must match the primary controller module. Mixed-revision redundant pairs are not supported by Honeywell.
Selection Guide
Use the following criteria to confirm TC-PRR021 is the correct module for your application:
- Step 1 — Identify Controller Series: Confirm whether your system uses C200 or C300 controllers. TC-PRR021 is designed for C200; C300 systems require TC-CCR016.
- Step 2 — Check Backplane Revision: Verify chassis backplane revision matches module requirements (refer to Honeywell System Planning Guide).
- Step 3 — Confirm Firmware Version: Primary and redundancy modules must run identical firmware. Check via Experion Station > Controller Diagnostics.
- Step 4 — Redundancy Cable: Ensure CC-PCF901 redundancy cable is available and routed correctly between primary and backup chassis.
- Step 5 — Licensing: Redundancy functionality may require an Experion PKS software license. Confirm with your Honeywell account manager or contact us.

Replacement & Compatibility FAQ
Q: Can TC-PRR021 replace 51309288-150 directly?
A: In most C200 applications, yes — the -225 suffix is a later revision with minor ECO changes. Verify firmware compatibility before hot-swap in a live system.
Q: Is TC-PRR021 compatible with C300 controllers?
A: No. C300 systems require TC-CCR016. Using TC-PRR021 in a C300 chassis will result in a module fault.
Q: Do I need a license to enable redundancy?
A: Experion PKS redundancy may require a software license key. Confirm with your Honeywell system administrator or contact Konmask for guidance.
Q: Can I use a refurbished module in a safety-critical loop?
A: Refurbished modules are tested to OEM specifications. For SIL-rated loops, consult your functional safety engineer and review Honeywell’s approved spare parts policy.
Q: What is the lead time for new OEM units?
A: In-stock units ship within 1–3 business days. For new OEM orders, lead time is typically 8–16 weeks. Konmask maintains surplus stock to bridge this gap.
