FAQ

Q: What is the primary function of this module?
A: It acts as a serial buffer/interface card that allows DeltaV MQ/MX controllers to communicate with Provox distributed I/O subsystems.

Q: Which controller types are supported?
A: Per InnoPLCSync, it is compatible with DeltaV MQ and MX controllers.

Q: Can this module be hot-swapped?
A: Refer to the DeltaV system manual for online replacement procedures. De-energizing the local bus is recommended before removal.

Installation Guidelines

1. Install the module in a DeltaV M-series or compatible rack.
2. Connect Provox distributed I/O serial cabling to the interface port.
3. Verify controller redundancy configuration if deploying in a redundant pair.
4. Confirm 12 VDC or 24 VDC local bus power matches your specific module revision.

Selection Tips

• Order KJ2101X1-BA1 when migrating or interfacing Provox I/O with DeltaV MQ/MX controllers.
• Verify power requirements before installation—supplier data conflicts on whether this module uses 12 VDC or 24 VDC local bus power.
• Confirm your specific module revision supports the required Provox I/O type (Control I/O or Distributed MUX I/O).
