FAQ
Q: Can I add multiple KJ3004X1-EA1 units in a single bus segment?
A: Yes, but ensure the total current does not exceed the carrier rating.
Q: Is this module compatible with Series 1 DeltaV I/O?
A: It is optimized for DeltaV M-series (Series 2) I/O; adapters may be required for older Series 1 carriers.
