Compatible Replacement & Equivalent Models
The following modules are verified or commonly referenced as functional replacements or equivalents for the 1C31166G01 within WDPF system architectures. Always validate firmware revision and backplane slot compatibility before substitution.
- 1C31166G02 – Westinghouse, same series, revised hardware revision; direct form-fit-function replacement candidate
- 1C31166G03 – Westinghouse, later revision with enhanced diagnostics; backward-compatible in most WDPF racks
- 1C31227G01 – Westinghouse WDPF Input Module, alternative channel configuration; verify I/O mapping before swap
- 5X00106G01 – Emerson WDPF-series input card (post-acquisition part numbering); functionally equivalent in supported racks
- 1C31194G01 – Westinghouse analog input module; cross-reference for specific signal-type applications
Konmask engineers can assist with cross-reference validation. Contact us before ordering a replacement if you are unsure of compatibility.

System Compatibility
- Primary Platform: Westinghouse WDPF (Distributed Processing Family) DCS
- Rack Compatibility: Standard WDPF I/O rack with appropriate backplane bus
- Controller Compatibility: WDPF WEStation, QSS, and associated processor modules
- Post-Acquisition Systems: Compatible with Emerson-managed WDPF installations (verify with site engineering)
- Not Compatible With: Emerson DeltaV, Ovation, or other non-WDPF platforms without hardware adaptation
Selection Guide
Use the following decision framework to select the correct module for your application:
- Step 1 – Confirm Platform: Verify your system is a Westinghouse WDPF DCS. Check rack model and backplane bus type.
- Step 2 – Identify Signal Type: Determine whether the failed or required module handles analog (4–20 mA, thermocouple, RTD) or digital (discrete) inputs.
- Step 3 – Check Revision Compatibility: Compare the G-suffix revision (G01, G02, G03) against your system’s firmware and hardware revision matrix.
- Step 4 – Validate Slot Assignment: Confirm the target rack slot accepts this module type per the WDPF hardware configuration document.
- Step 5 – Choose OEM or Equivalent: If the original 1C31166G01 is unavailable, select from the compatible equivalents listed above with Konmask’s cross-reference support.
- Step 6 – Request a Quote: Contact Konmask with your quantity, required delivery timeline, and any certification requirements.

Replacement & Compatibility FAQ
Q: Can I use a 1C31166G02 to replace a 1C31166G01?
A: In most cases yes — the G02 is a hardware revision of the same module family. However, confirm with your WDPF system documentation or contact Konmask to validate before installation.
Q: Is the 1C31166G01 compatible with Emerson Ovation DCS?
A: No. The 1C31166G01 is specific to the Westinghouse WDPF platform. Ovation uses a different hardware architecture and is not compatible.
Q: Do you supply tested/refurbished units?
A: Yes. All refurbished units are fully tested and clearly labeled. Test reports are available upon request.
Q: What is the lead time for out-of-stock units?
A: Typically 5–15 business days depending on sourcing. Contact us for urgent requirements — we maintain a global supplier network for legacy WDPF parts.
Q: Can you provide a Certificate of Conformance (CoC)?
A: Yes, CoC and inspection reports are available for all tested units. Please request at time of order.
