Application-Specific FAQ
Q: Is the KJ3221X1-BA1 compatible with DeltaV M-Series or Classic DeltaV controllers?
A: No. This module is designed specifically for the DeltaV S-Series I/O subsystem. It is not backward-compatible with DeltaV M-Series or Classic (pre-S-Series) hardware. For M-Series, the equivalent module is the KJ3221X1-BA1’s M-Series counterpart — contact us to confirm the correct part for your system.
Q: Can this module be used in SIL 2 safety loops?
A: The KJ3221X1-BA1 may be suitable for SIL-assessed applications depending on your safety architecture. Refer to the Emerson DeltaV SIL datasheet and consult your functional safety engineer. Konmask.com does not provide SIL certification services.
