The 35 VDC/1 A rating and environmental figures are reported consistently across available technical records. The DeltaV S-Series hardware documentation also lists KJ4006X1-BD1 specifically as the Interface Term Block, distinguishing it from the 8-channel, fused, H1, thermocouple/mV, RTD, and other terminal-block variants in the same KJ4006X1 family.
Product Introduction
The Emerson KJ4006X1-BD1 is an interface terminal block used within the DeltaV S-Series architecture. Its job is physical and electrical interfacing rather than control execution: it provides the termination and interface point associated with compatible DeltaV I/O hardware. The associated alternate part number is 12P4722X052.
A critical procurement point is the distinction between the terminal block and the I/O card. KJ4006X1-BD1 is not an independent PLC/DCS I/O module. Its compatibility depends on the installed card, terminal-block key position, system arrangement, and field wiring.

Application Scenarios & Field Pitfalls
The practical issue with this part usually appears during maintenance: the terminal block can look interchangeable with other KJ4006X1 variants, while the internal interface and keying arrangement may be different.
Typical applications:
- DeltaV S-Series DCS I/O cabinets
- Replacement of damaged or aged interface terminal blocks
- Maintenance of legacy DeltaV serial/interface installations
- Brownfield plant shutdown and spare-parts replacement
- Field-wiring termination associated with compatible S-Series interface cards
Engineer’s checks before replacement:
- Verify the I/O card first. -BD1 is keyed according to the installed card. Do not select the terminal block simply because the family number matches.
- Do not substitute another terminal-block suffix without checking the hardware documentation. -BA1, BB1, BC1, BE1, BF1, BG1, BH1, BJ1 and other variants perform different interface functions.
- Observe removal/insertion restrictions. Available DeltaV installation documentation states that a terminal block may be added or removed with system power applied only when no I/O card is installed and no field wiring is connected to the terminal. Follow the applicable plant electrical and hazardous-area procedure.
- Preserve field wiring identification. Before replacement, document terminal positions, cable labels, card type, key position, and cabinet location. A physically compatible block with incorrect field termination can create a commissioning problem that is much harder to diagnose than the original hardware fault.

Procurement Note
For a replacement order, specify , together with the installed DeltaV I/O/interface card, cabinet or carrier location, terminal-block key position, and field-wiring configuration. Do nothe as a generic terminal strip.
For legacy DeltaV equipment, the exact suffix matters more than physical appearance. If the existing assembly is being replaced during a shutdown, matching the terminal block to the installed card before removing field wiring is the safer approach.
