Product Introduction & Supply Chain Strategy
The Emerson KJ3004X1-BA1 (VE4002S2T2B1) is an 8-channel standard terminal block designed for Emerson DeltaV Series 2 Distributed Control System (DCS) racks. It provides the physical wiring interface between field transmitters, control valves, and the plugged-in DeltaV I/O card, ensuring secure signal execution and isolation across chemical processing, refining, and power generation facilities.
Sourcing the KJ3004X1-BA1 as New Surplus secures your DCS infrastructure against unexpected channel failures without requiring high-cost emergency orders or plant system retrofits. Unused New Surplus units eliminate the risks associated with second-hand terminal blocks—such as stripped screw terminals, hairline plastic carrier cracks, and internal corrosion—ensuring zero signal degradation and zero unplanned process trips.
Installation & Configuration Guide
Stage 1: Pre-Installation (Prep & Safety)
- Execute full Lock-Out/Tag-Out (LOTO) procedures on field instrument loops powered through the target terminal block.
- Put on an anti-static wrist strap connected to cabinet earth ground before handling system components.
- Label all field wiring pairs cleanly and photograph terminal assignments on the original KJ3004X1-BA1 block.
Stage 2: Removal
- Disconnect field wires from the screw terminals using an appropriately sized slotted screwdriver.
- Unlatch the I/O interface module seated on the terminal block and pull it forward to remove it from the carrier.
- Press the terminal block release latches on the top and bottom of the unit, then pull the block straight out from the 8-channel carrier base.
Stage 3: Installation (Clone & Seat)
- Inspect the carrier keying pegs to verify they match the slot configuration required for your specific I/O card type.
- Align the rear tabs of the new KJ3004X1-BA1 with the carrier slot and press firmly until both retaining latches click into place.
- Re-insert the field wiring into the screw terminals according to your wiring schematic and tighten screws to 0.5 N·m torque. Re-seat the I/O module onto the terminal block.
Stage 4: Power-On & Testing
- Re-energize field loop power supplies and check voltage levels across terminals 1 through 8.
- Verify that the seated DeltaV I/O module initializes with solid green power and channel status LEDs.
- Perform a loop check from the DeltaV Diagnostics station to verify analog output signals or input readings match field instrument values.

Firmware/Software Versions & Upgrade Notes
- Hardware Revision Compatibility: The KJ3004X1-BA1 is a passive hardware termination assembly, making it universally compatible with all DeltaV v6.x through current v14.x software environments.
- Keying Pin Alignment: Ensure the mechanical keying pegs on the terminal block match the assigned I/O module type (e.g., Analog Input vs. Discrete Output). Forcing an incorrectly keyed I/O card onto the block can bend internal connector pins.
- Upgrade/Downgrade Risks: No firmware flash is required for this hardware module. However, replacing passive terminal blocks with fused or surge-protected variants requires verifying field loop power constraints before startup.
Frequently Asked Questions (FAQ)
Why is this New Surplus unit priced higher than used terminal blocks online?
Used terminal blocks often suffer from stripped screw threads, micro-fractured terminal housings, and contact fatigue caused by repeated wiring cycles. Our Emerson inventory consists strictly of New Surplus—original, uninstalled units kept in pristine conditions. Paying a small premium for New Surplus guarantees firm wiring retention and prevents intermittent signal loss that can shut down active control loops.
Is this Emerson guaranteed to be an authentic OEM unit?
Yes. Every unit we sell is guaranteed to be an original Emerson factory-manufactured product. It is not a generic knock-off, repaired unit, or pulled component. Each block undergoes thorough visual and mechanical latch verification prior to shipment.
What is the difference between part number and VE4002S2T2B1?
They refer to the exact same physical product. Emerson uses “” as the raw component part number stamped on the hardware casing, while “VE4002S2T2B1” serves as the catalog model number used for system ordering and billing.
Can I replace the terminal block while the DeltaV I/O card is powered and active?
No. Removing the terminal block while under power disrupts active field loops and will cause signal faults across connected channels. Always unseat the active I/O module and isolate field power before swapping the terminal block base.
Does this terminal block require external termination jumpers or fuses?
This model is a standard 8-channel screw termination block. If your loop design requires individual channel fusing, you must verify whether your application uses external inline fuse holders or requires the fused variant (VE4002S2T2B2) instead.
What warranty is provided with this New Surplus DeltaV terminal block?
This New Surplus Emerson terminal block comes backed by a full 1-year operational replacement warranty, complete with a signed quality check verification from our warehouse team.
