Selection Guide
Use the following criteria to confirm the KJ2201X1-JA1 is the correct terminal block for your application:
- ✅ Redundant SLS architecture required? → KJ2201X1-JA1 is the correct choice.
- ✅ Single SLS module (non-redundant)? → Consider KJ2201X1-BA1 instead.
- ✅ Replacing an existing terminal block? → Match the reference number (12P3323X022) and hardware revision on the existing unit.
- ✅ New system build? → Specify DeltaV SIS version and carrier type to Konmask.com for confirmation.
- ✅ Retrofit or upgrade project? → Provide existing BOM or system drawing for cross-reference validation.

Replacement & Compatibility FAQ
Q: Can I use KJ2201X1-JA1 to replace a non-redundant SLS terminal block?
A: The JA1 suffix denotes the redundant variant. Using it in a non-redundant slot may cause configuration errors. Consult your DeltaV SIS system engineer before substitution.
Q: Is 12P3323X022 the same as KJ2201X1-JA1?
A: Yes — 12P3323X022 is Emerson’s internal reference/revision number for the KJ2201X1-JA1. Both numbers refer to the same physical part.
Q: What is the difference between KJ2201X1-JA1 and KJ2201X1-JA2?
A: The JA2 is a later hardware revision. While functionally similar, firmware and carrier compatibility should be verified with Emerson or Konmask.com before substitution.
Q: Do you supply tested/refurbished units?
A: Yes. All refurbished units are tested to OEM specifications and include a 12-month warranty. Test reports are available upon request.
Q: Can Konmask.com source this part if it’s not in stock?
A: Yes. We maintain an extensive supplier network for Emerson DeltaV components. Contact us with your timeline and we will provide availability and lead time within 24 hours.
