Interfaces four independent FOUNDATION Fieldbus H1 segments with the DeltaV control system.
Product Identification
KC3030X1-BK2 is an Emerson DeltaV M-series FOUNDATION Fieldbus H1 4-Port Plus I/O module. It connects four H1 segments to the DeltaV controller and must be selected by the complete BK2 hardware identity rather than by the KC3030 family alone.
The current KC3030 family documentation establishes the four-port H1 architecture, but later order codes and software requirements must not be applied automatically to BK2. The installed terminal block, DeltaV release and approved migration path therefore remain part of the exact replacement decision.

Functions
Transfers cyclic process data, device status and scheduled control communication for configured H1 devices.
Separates the I/O card identity from the external segment power conditioners, terminators and field wiring.
Provides a controlled service point for segment-by-segment diagnostics and lifecycle maintenance.
Applications
- DeltaV process-control systems using the KC3030X1-BK2 revision of the four-port Fieldbus H1 Plus interface.
- Multi-segment H1 installations where power, terminators, barriers and device loading are engineered per segment.
- Lifecycle replacement requiring the installed card, terminal block, controller release and fieldbus database to remain aligned.
- Migration reviews where a later KC3030 revision is considered only through documented Emerson compatibility guidance.
Lifecycle
- Export the DeltaV configuration, module assignment, segment schedules and a device list for all four H1 ports.
- Record the KC3030X1-BK2 and terminal-block labels, carrier slot, controller revision and DeltaV release.
- Check segment voltage, current load, power conditioner, both terminators, shields and intrinsic-safety hardware before blaming the card.
- Replace the module under the DeltaV I/O maintenance procedure and restore one segment at a time while monitoring device status.
- Close the work only after every scheduled device communicates normally and control loops pass their functional checks.

FAQ
Can a current KC3030 card replace KC3030X1-BK2?
Treat it as a migration, not a visual equivalent. Emerson documentation must confirm the terminal block, DeltaV release, controller and database conversion path.
What segment data should accompany an enquiry for KC3030X1-BK2?
Provide the four port assignments, device list, cable length, power conditioner, terminators, barriers, segment voltage and terminal-block label.
Why can devices disappear after fitting KC3030X1-BK2?
A missing terminator, weak segment supply, reversed spur, shield fault, address conflict or unscheduled device can interrupt H1 communication even when the I/O card is healthy.
How many devices can each port of KC3030X1-BK2 support?
The practical limit is set by the engineered segment power, cable, barriers and intrinsic-safety method; do not use a headline device count without recalculating the installed segment.
How should the four ports on KC3030X1-BK2 be recommissioned?
Restore and observe one H1 segment at a time, verify scheduled communication and device status, then perform loop checks before enabling the next segment.
