Compatible Replacement & Equivalent Models
When the OEM part is unavailable or lead times are unacceptable, the following alternatives may be evaluated as functional equivalents. Always verify electrical and mechanical compatibility before substitution:
- Emerson / Fisher-Rosemount: Other KC40-series terminal blocks within the same DeltaV I/O family
- Phoenix Contact: VARIOFACE or FLKM series modular terminal blocks (verify pin-out and signal type)
- Weidmüller: B2L / BCZ series DIN rail terminal blocks
- Wago: 750-series or 855-series field termination modules
- Rockwell / Allen-Bradley: 1492-series terminal blocks (for cross-platform migration projects)
Note: Replacement compatibility depends on your specific DeltaV system revision, I/O card type, and field wiring configuration. Contact Konmask technical support for a validated recommendation.

Selection Guide
Use the following criteria to confirm this part is correct for your application:
- Step 1 – Verify part number: Confirm both KC4011X1-BD1 and cross-reference 12P6758X022 match your BOM or existing label.
- Step 2 – Identify I/O card type: Match the terminal block series to your DeltaV I/O card (AI, AO, DI, DO).
- Step 3 – Check channel count: Confirm the number of field termination points required per card.
- Step 4 – Assess condition requirement: Choose New for greenfield projects; Tested Surplus for MRO/spares.
- Step 5 – Confirm lead time: Contact us for real-time stock availability and expedited shipping options.

Replacement & Compatibility FAQ
Q: Is KC4011X1-BD1 the same as 12P6758X022?
A: Yes. 12P6758X022 is Emerson’s catalog cross-reference number for the KC4011X1-BD1 terminal block assembly. Both numbers refer to the same physical part.
Q: Can I use a Phoenix Contact terminal block as a direct replacement?
A: Potentially, but it requires engineering validation. Pin-out, signal type, and mechanical form factor must all match. We recommend using the OEM part to avoid re-wiring costs.
Q: Do you supply tested surplus units?
A: Yes. All surplus units undergo functional testing and are supplied with a test report. Contact us for details.
Q: What is the lead time for new units?
A: Stock availability varies. Contact us for real-time inventory status. Surplus units typically ship within 3–5 business days.
Q: Is this part compatible with DeltaV version 14 and above?
A: The KC4011X1-BD1 is a passive termination component and is not firmware-dependent. Compatibility is determined by the I/O card type, not the DeltaV software version.
