Emerson KJ4001X1-CJ1 12P1902X032 – DeltaV DCS Channel Terminal Block | DeltaV S-Series Platform
The Emerson KJ4001X1-CJ1 12P1902X032 is a Channel Terminal Block designed for the Emerson DeltaV Distributed Control System (DCS). As a critical field-wiring interface component within the DeltaV S-Series I/O subsystem, it provides a reliable, organized termination point between field instruments and DeltaV I/O cards. Procurement engineers specifying DeltaV spare parts or replacement terminal blocks will find this unit fully interchangeable within the DeltaV S-Series architecture.
At Konmask.com, we source this component through verified industrial supply channels, ensuring authenticity and traceability for mission-critical process control environments including oil & gas, chemical, power generation, and pharmaceutical manufacturing.

System Architecture & Signal Flow
Within the DeltaV S-Series I/O architecture, the KJ4001X1-CJ1 terminal block sits at the field-wiring layer. Field instrument cables terminate at the screw-clamp terminals; signals pass through the terminal block into the associated DeltaV I/O card seated in the carrier. The DeltaV controller then reads or writes process values via the DeltaV fieldbus backplane. This clean signal path — field → terminal block → I/O card → controller — is fundamental to DeltaV’s modular, scalable design philosophy.

Technical FAQ
Q: Is KJ4001X1-CJ1 compatible with all DeltaV S-Series I/O cards?
A: It is designed for the DeltaV S-Series I/O subsystem. Compatibility depends on the specific I/O card type and carrier. Please confirm your I/O card model number when inquiring.
Q: What is the difference between KJ4001X1-CJ1 and other DeltaV terminal block variants?
A: Different suffix codes (e.g., -BA1, -CA1) may indicate different channel counts or wiring configurations. The KJ4001X1-CJ1 / 12P1902X032 is a specific Emerson-released revision — always match both part numbers for exact replacement.
Q: Can this terminal block be used in a CHARM (Characterization Module) architecture?
A: Standard S-Series terminal blocks are distinct from CHARM I/O carriers. Please specify your DeltaV architecture version when ordering.
Q: Do you provide a warranty?
A: Yes. Konmask.com provides a 90-day functional warranty on all verified components. Extended warranty options available for volume orders.
Q: What is the lead time?
A: In-stock units ship within 3–5 business days internationally. Lead time for sourced units is typically 2–4 weeks depending on availability.
