Product Overview
Emerson KJ4006X1-BD1 12P4722X092 DeltaV Replacement Solution: Seamless Transition from Legacy I/O Terminal Blocks
The Emerson KJ4006X1-BD1 12P4722X092 is a field-proven DeltaV series I/O terminal block designed for direct integration with Emerson’s distributed control system architecture. As legacy DeltaV installations age and original terminal block assemblies reach end-of-life or become difficult to source, facilities engineers and automation procurement teams increasingly require a verified, drop-in replacement that preserves existing wiring infrastructure, maintains communication integrity, and eliminates the need for costly panel redesigns or PLC reprogramming.
This replacement solution is engineered for industrial sites running Emerson DeltaV S-series and M-series controllers, where the KJ4006X1-BD1 12P4722X092 terminal block serves as the critical interface between field instrument wiring and the DeltaV I/O subsystem. Whether your facility is managing a phased modernization of a legacy DCS, responding to an unplanned failure, or building a strategic spare parts inventory, this unit provides the physical and electrical compatibility required for a smooth, low-risk transition.

Seamless Upgrade Solutions
A successful DeltaV I/O terminal block replacement rarely involves a single component in isolation. In practice, field engineers replacing the KJ4006X1-BD1 12P4722X092 are often simultaneously addressing adjacent components that have experienced equivalent wear or obsolescence. During the migration process, it is common to inspect and replace the associated DeltaV I/O carrier — such as the KJ4001X1-BA1 or KJ4001X1-BC1 series — which provides the backplane connection between the terminal block and the I/O card. If the I/O card itself is flagged for replacement, units such as the KJ3221X1-BA1 analog input card or the KJ3002X1-BA1 digital output card are frequently sourced alongside the terminal block to complete a full channel restoration.
For sites upgrading communication infrastructure at the same time, the DeltaV CIOC (Controller I/O Card) and associated Ethernet communication modules may also be part of the scope. HART-enabled field instruments connected through this terminal block — including Rosemount 3051 pressure transmitters or Fisher FIELDVUE DVC6200 digital valve controllers — should be verified for HART revision compatibility during the commissioning phase. The terminal block’s HART pass-through behavior is transparent to the I/O card, so no changes to the DeltaV control strategy or module parameters are required.
In control cabinet environments where multiple terminal blocks are being refreshed, it is efficient to simultaneously evaluate the DeltaV power supply modules (such as the KJ4009X1-BA1 power conditioner) and the marshalling cabinet terminal strips. Signal isolators — particularly for long cable runs or noisy industrial environments — may be inserted between the field wiring and the terminal block without affecting the DeltaV system’s channel configuration. For sites that have not yet migrated their HMI layer, the DeltaV Operate workstation software and associated DeltaV ProfessionalPLUS controller licensing should be reviewed to ensure the replacement I/O channel is recognized correctly after the hardware swap.
Programming cables such as the KBUSB-1 or equivalent DeltaV USB interface are recommended on-site during commissioning to allow real-time diagnostics and channel verification through DeltaV Diagnostics without requiring a full system shutdown. This is particularly important in continuous process environments — petrochemical, pharmaceutical, or power generation — where minimizing downtime during the terminal block replacement is a primary operational constraint.
Retrofit Guidance FAQ
Q: Do I need to rewire field instruments when replacing the KJ4006X1-BD1 12P4722X092?
No. The KJ4006X1-BD1 12P4722X092 uses an identical screw-terminal layout and pitch to the original unit. Field wiring connections — including 4–20 mA signal pairs, HART communication lines, and shield grounds — can be transferred directly without modification. Label each wire before removal and reconnect in the same terminal positions.
Q: Is reprogramming the DeltaV controller required after the swap?
No reprogramming is required. The terminal block is a passive wiring interface; it does not contain firmware or configuration data. The DeltaV I/O card and controller retain all module parameters, channel assignments, and control strategy logic. After physical replacement, perform a channel diagnostic check in DeltaV Diagnostics to confirm signal integrity.
Q: Is this replacement compatible with HART-enabled field devices?
Yes. The KJ4006X1-BD1 12P4722X092 supports HART pass-through to the DeltaV I/O card. HART communication between the DeltaV system and HART-capable field instruments (transmitters, valve positioners, analyzers) is maintained without any additional configuration.
Q: Can the terminal block be replaced while the DeltaV system is running?
Hot-swap capability depends on the I/O card type and the DeltaV system configuration. For non-redundant I/O channels, a controlled shutdown of the affected channel is recommended. For redundant I/O configurations, consult the DeltaV Hardware Installation Guide for the specific hot-swap procedure applicable to your I/O carrier and card combination.
Q: What if the I/O carrier or I/O card is also damaged?
If the I/O carrier (e.g., KJ4001X1-BA1) or the I/O card shows fault indicators, those components should be sourced and replaced as part of the same maintenance window. TOPNLMS stocks a range of DeltaV I/O subsystem components and can assist with multi-part procurement to minimize the number of separate maintenance interventions.
Q: How do I verify the replacement unit before installation?
Each unit shipped by TOPNLMS undergoes pre-shipment functional inspection. Upon receipt, visually inspect the terminal block for physical damage, verify the part number label matches KJ4006X1-BD1 12P4722X092, and confirm the connector interface aligns with the I/O carrier slot before installation.
