Replacement & Compatibility FAQ
Q: Can KJ3221X1-BA1 replace KJ3221X1-BA2?
A: Yes, in most cases. The BA2 is a hardware revision of the BA1. Verify your DeltaV version supports both revisions before swapping.
Q: Is this card compatible with DeltaV M-Series?
A: No. The KJ3221X1-BA1 is designed exclusively for the S-Series carrier architecture. M-Series requires a different card family.
Q: Can I use a Rockwell 1756-DNB as a drop-in replacement?
A: No. The 1756-DNB is a ControlLogix module and requires a separate controller platform. Integration with DeltaV would require an OPC or EtherNet/IP gateway.
Q: What is the lead time for KJ3221X1-BA1?
A: Standard stock items ship within 3–7 business days. Contact us for current availability and expedited options.
Q: Do you provide installation support?
A: Yes. Konmask offers remote technical support for DeltaV configuration and DeviceNet commissioning. Contact [email protected].
