System Compatibility
| Platform | Compatible | Notes |
|---|---|---|
| Experion PKS R400+ | ✅ Yes | Primary target platform |
| Experion PKS R300 | ✅ Yes | Verify revision suffix |
| TotalPlant Solution (TPS) | ✅ Yes | Legacy TPS I/O termination |
| Experion LX / LS | ⚠️ Verify | Confirm with Honeywell BOM |
| Safety Manager / FSC | ❌ No | Different power architecture |
Selection Guide
Use the following criteria to confirm the MC-TLPA02 is the correct part for your application:
- Identify your DCS platform: Confirm Experion PKS or TPS — not Safety Manager or Experion LX.
- Check the termination assembly model: The MC-TLPA02 pairs with specific MC-series I/O termination assemblies. Cross-reference your cabinet BOM.
- Verify the P/N suffix: 51309204-175 denotes a specific hardware revision. Confirm this matches your existing installed base.
- Assess condition requirements: For critical loops, specify New or Surplus New. Refurbished units are suitable for non-critical or spare applications.
- Quantity & lead time: Contact us for bulk pricing and availability on short lead-time requirements.

Replacement & Compatibility FAQ
Q: Can the MC-TLPA02 replace the MC-TLPA01 directly?
A: In most cases yes, but the hardware revision suffix must be verified. Some earlier TPS cabinets require the -100 or -150 suffix variant. Confirm with your system documentation.
Q: Is this module compatible with Honeywell Safety Manager?
A: No. The Safety Manager uses a separate power architecture. Do not substitute MC-TLPA series adapters in SIL-rated safety loops.
Q: Do you provide a certificate of conformance (CoC)?
A: Yes, CoC and test reports are available for new and surplus new units upon request.
Q: What is the lead time for new units?
A: Surplus stock ships within 3–5 business days. New OEM orders may require 4–12 weeks depending on Honeywell’s current production schedule.
Q: Can I return a module if it doesn’t fit my system?
A: Yes, within 30 days of receipt in original condition. Please contact support before returning.
