The KJ3004X1-BA1 (12P2093X042) is a Series 2 Foundation Fieldbus H1 interface card designed for the Emerson Electric DeltaV™ M-Series distributed control system. It provides the primary digital communication link between the DeltaV controller and intelligent H1 field devices, enabling reliable bi-directional data exchange for transmitters, valve positioners, and other smart instruments.
Built for mission-critical industrial environments, this module supports advanced device diagnostics and Control-in-the-Field (CIF) functionality, allowing control strategies to be distributed closer to the process. Its hot-swappable design enhances system availability by permitting replacement without shutting down the carrier or interrupting active control operations.
Engineered for high reliability, the card supports redundancy strategies to reduce communication risk and ensure continuous access to critical field data in demanding plant-floor conditions.

The KJ3004X1-BA1 is widely deployed in:
Oil & gas refining
Chemical processing plants
Water and wastewater treatment
Power generation facilities
It integrates seamlessly with standard H1 power conditioners and field junction boxes, forming a robust Fieldbus segment architecture within the DeltaV system.
Does the KJ3004X1-BA1 supply power to the Fieldbus segment?
No. The module manages communication and logic only. A separate Fieldbus power conditioner must supply 9–32 VDC to energize devices on the H1 segment.
Is this module compatible with Series 1 DeltaV carriers?
It is a Series 2 component. While physically compatible with most M-series carriers, firmware and controller revisions should be verified before integrating with older Series 1 systems.
Can the module be replaced during operation?
Yes. The DeltaV architecture supports hot-swapping, enabling module replacement without shutting down the control system, provided redundancy and power design are properly implemented.
