DeltaV Field Wiring Solution – EMERSON KJ400X1-CJ1 | 12P1902X032
Where This Product Is Used
The EMERSON KJ400X1-CJ1 (12P1902X032) Terminal Block is a field-wiring interface component designed for use within Emerson DeltaV Distributed Control System (DCS) architectures. It is deployed wherever field instrument signals must be reliably terminated and routed to DeltaV I/O subsystem modules.
Typical installation environments include:
- Oil & Gas — upstream wellhead control panels, midstream compressor stations, downstream refinery DCS marshalling cabinets
- Chemical & Petrochemical — reactor loop instrumentation, safety-instrumented system (SIS) field junction boxes
- Power Generation — turbine control panels, boiler management system (BMS) I/O racks
- Pulp & Paper / Food & Beverage — process line DCS field termination panels
- Pharmaceutical — cGMP-compliant process control cabinets requiring traceable I/O wiring

Application-Specific FAQ
Q: Is KJ400X1-CJ1 the same as 12P1902X032?
A: Yes. These are two valid Emerson part number references for the same terminal block assembly. KJ400X1-CJ1 is the catalog number; 12P1902X032 is the manufacturing/revision reference. Both are interchangeable for procurement purposes.
Q: Which DeltaV I/O modules does this terminal block support?
A: The KJ400X1-CJ1 is designed for use with specific DeltaV I/O subsystem carriers. Please provide your I/O module model number when inquiring to confirm compatibility with your specific DeltaV revision.
Q: Can this terminal block be replaced without shutting down the DeltaV controller?
A: DeltaV I/O subsystems support hot-swap at the module level in many configurations. However, field wiring must be de-energized per site safety procedures before disconnecting the terminal block. Consult your DeltaV system documentation and site LOTO procedures.
Q: Do you provide a warranty on this part?
A: New units carry the standard Emerson manufacturer warranty. Refurbished units carry a Konmask 90-day functional warranty. Terms are confirmed at time of sale.
Q: Can you supply a full DeltaV I/O rack or marshalling cabinet?
A: Yes. Konmask.com supports turnkey DeltaV spare parts packages and complete I/O rack assemblies. Contact us with your project BOM for a consolidated quotation.
