EMERSON VE4002S1T1B2 – Digital Output Module | DeltaV DCS Series
Engineering Background
The EMERSON VE4002S1T1B2 (also cross-referenced as KJ3001X1-BG1 and 12P0557X162) is a field-proven digital output module designed for the EMERSON DeltaV Distributed Control System platform. DeltaV is one of the most widely deployed process automation architectures in refining, chemical, pharmaceutical, and power generation industries. This module serves as the final command interface between the DCS controller and field actuators, executing discrete output signals with deterministic timing and high channel density.
Product Positioning
Procurement engineers sourcing replacement or expansion I/O for DeltaV systems will find the VE4002S1T1B2 to be a direct, plug-compatible solution. Konmask.com supplies this module from verified industrial surplus and authorized distribution channels, with full traceability documentation available upon request. Suitable for both MRO (Maintenance, Repair & Operations) replacement and greenfield system expansion.

- Plug-and-play integration: DeltaV controller auto-discovers module type and configures I/O tags automatically
- High channel density: 8 DO channels per module slot minimizes cabinet footprint
- Optical isolation: Protects controller backplane from field-side transients and ground loops
- Deterministic scan: Output updates synchronized to DeltaV controller execution cycle for precise timing
System Architecture & Signal Flow
In a DeltaV architecture, the VE4002S1T1B2 is installed into an I/O carrier mounted on a DIN rail or marshalling cabinet. The DeltaV controller communicates with the module over the proprietary I/O bus via the carrier backplane. Each output channel drives a 24 VDC sourcing signal to field devices (solenoid valves, motor starters, indicator lamps, relay coils). The module’s onboard ASIC handles channel scanning, diagnostics reporting, and LED status updates independently of the controller scan cycle, ensuring real-time field feedback even during controller communication interruptions.
Signal flow: DeltaV Controller → I/O Bus → VE4002S1T1B2 Backplane → Optical Isolator → Output Driver → Field Terminal → Actuator

Technical FAQ
Q: Is VE4002S1T1B2 compatible with all DeltaV controller versions?
A: Yes. The module is backward and forward compatible with DeltaV MD, MD Plus, SD, and SD Plus controllers running DeltaV v10.3 and above. Confirm your carrier type (Series 2 vs CHARM) before ordering.
Q: Can this module be used in SIL-rated safety loops?
A: The VE4002S1T1B2 is not a SIS-rated module. For SIL 1/2 applications, EMERSON’s SIS I/O modules (e.g., KJ3002X1 series) should be specified. Consult your functional safety engineer.
Q: What is the difference between VE4002S1T1B2 and KJ3001X1-BG1?
A: These are the same physical module. VE4002S1T1B2 is the EMERSON catalog part number; KJ3001X1-BG1 is the assembly/revision suffix used in some procurement and MRO databases. 12P0557X162 is the PCB assembly reference. All three refer to the identical hardware.
Q: Do you offer volume pricing for plant-wide I/O replacement projects?
A: Yes. Contact support@konmask.com with your full BOM for a project-level quotation. Volume discounts apply for orders of 5+ units of the same part number.
Q: What if the module fails within the warranty period?
A: Konmask provides a 12-month warranty. Defective units are replaced or refunded at no cost. RMA process initiated within 24 hours of fault report.
