Product Introduction (Rotation Engine)
Field wiring mistakes on a DeltaV I/O rack usually trace back to the wrong terminal block or unclear channel mapping. The EMERSON is the standard I/O terminal block for the Emerson DeltaV Series 2 I/O platform. It provides the field-wiring interface for compatible DeltaV I/O modules, supporting orderly termination of process signals in discrete, analog, and communication I/O applications.
This terminal block is a passive mechanical interface, not an I/O module or processor. It mates with the appropriate DeltaV Series 2 carrier and helps maintenance teams replace or re-terminate I/O wiring without disturbing the full field cable bundle. For plants running DeltaV Series 2 I/O, keeping a verified spare reduces turnaround delays and avoids last-minute sourcing when a terminal block is damaged during commissioning or retrofit work.

Key Selling Points & Differentiators
- Direct replacement for DeltaV Series 2 standard I/O terminal block applications.
- Passive design means no firmware, no configuration, and no power draw.
- Helps maintain consistent wiring identification during FAT/SAT and loop checks.
- Factory-sealed surplus lowers DOA risk versus pulled used terminal blocks.
- 1-year functional warranty covers manufacturing defects and DOA failures.
- Not recommended as a fused terminal block, thermocouple/RTD terminal block, mass terminal block, DeltaV CHARMs FTA, or SLS safety terminal block.
Quality Transparency SOP (DYNAMIC GENERATION)
- Visual inspection: Check housing, terminal clamps, labeling area, latch mechanism, and pin contacts for damage or corrosion.
- Part verification: Confirm model KJ4001X1-CA1 and alternate P/N 12P0623X042 against the packing list.
- Mechanical test: Verify terminal block engagement, latch retention, and clamp tension.
- Continuity test: Check pin-to-terminal continuity with a multimeter to confirm clean signal paths.
- Fitment check: Confirm proper mating with the compatible DeltaV Series 2 carrier before final packing.
- Final packing: Anti-static bag, moisture barrier, shock-safe boxing, and photo-documented QA.
Technical Risk Avoidance (DYNAMIC GENERATION)
❗ Do not treat KJ4001X1-CA1 as an I/O module, logic solver, or processor. It is a standard I/O terminal block.
❗ Verify carrier compatibility before installation. This terminal block must mate with the correct DeltaV Series 2 I/O carrier.
❗ Do not substitute KJ4001X1-CA1 for KJ4001X1-CB1, KJ4001X1-CC1, KJ4001X1-CG1, or KJ4001X1-CJ1 without engineering approval. Each suffix defines a different terminal block type.
❗ Confirm wiring diagrams and channel assignments before energizing. Miswired terminal blocks can create false I/O faults even with healthy modules.
Buyer’s FAQ
Is this a genuine OEM part?
Yes. This is an OEM Emerson DeltaV component supplied as new surplus / factory sealed. We do not rebrand or relabel third-party equivalents.
Is it new or refurbished?
Listed as New Original (New Surplus) / Factory Sealed unless otherwise stated. Any deviation in condition will be disclosed before shipment.
Can I use it as a direct replacement?
Yes, for DeltaV Series 2 standard I/O terminal block applications. Confirm the carrier type and terminal block configuration first.
What is the alternate part number?
The alternate part number is 12P0623X042. Always verify both numbers against your installed hardware before ordering.
What warranty is included?
A 1-year functional warranty covers manufacturing defects and DOA failures. Damage from incorrect carrier mating, misapplication, or improper installation is not covered.
