Selection Guide
Use the following criteria to confirm the KJ3222X1-BA1 is the correct module for your application:
- ✅ Your system uses Emerson DeltaV DCS with standard I/O carriers
- ✅ You require 8-channel discrete/digital input acquisition
- ✅ Input signals are 24 VDC dry or wet contact
- ✅ You need optical isolation per channel
- ✅ Operating environment is within 0–60°C
- ⚠️ If you need 16 channels → consider KJ3221X1-BA1
- ⚠️ If you need HART pass-through → verify KJ3224X1-BA1 applicability
- ⚠️ If your DeltaV version is v15+ → confirm backward compatibility with Emerson or Konmask support

Replacement & Compatibility FAQ
Q: Can KJ3222X1-BA1 replace KJ3222X1-BB1 directly?
A: Yes, in most cases. The BB1 is a hardware revision of the BA1 with the same functional specification. Verify your DeltaV version supports both revisions.
Q: Is this module compatible with DeltaV SIS (Safety Instrumented System)?
A: The standard KJ3222X1-BA1 is not a SIS-rated module. For SIL-rated applications, consult Emerson’s SIS I/O portfolio.
Q: Can I use a refurbished unit in a production environment?
A: Yes, provided the unit passes functional testing and your site’s maintenance policy permits refurbished spares. All Konmask refurbished units are tested and documented.
Q: What is the difference between KJ3222X1-BA1 and 12P2532X072?
A: These are the same module. 12P2532X072 is the Emerson internal reference/OEM part number; KJ3222X1-BA1 is the commercial catalog number.
Q: Do you provide a certificate of conformance (CoC)?
A: Yes. CoC, test reports, and serial number documentation are available upon request for all units.
