Compatible Replacement & Equivalent Models
The following modules are functionally equivalent or drop-in compatible replacements for the KJ3001X1-BG1 in DeltaV systems. Always verify firmware revision and carrier compatibility before substitution.
- KJ3001X1-BA1 — Earlier revision of the same DO 24 VDC isolated module; functionally equivalent in most DeltaV configurations
- KJ3001X1-BB1 — Intermediate revision; compatible with same carrier and I/O bus
- KJ3001X1-BC1 / BD1 / BE1 / BF1 — Progressive hardware revisions; same electrical specification
- KJ3002X1-BA1 — DO module with different channel count; verify channel requirements before substitution
- VE3008 (Emerson CHARM DO) — CHARM-based isolated DO for DeltaV S-series; requires CHARM I/O card infrastructure
- Third-party DeltaV-compatible DO modules — Contact Konmask for vetted alternatives
Note: Revision suffixes (BA1, BB1, BG1, etc.) indicate hardware revisions. Confirm compatibility with your DeltaV system version and I/O carrier before ordering.
Why Choose the Original Model
- Guaranteed DeltaV Compatibility: Factory-validated for seamless integration with Emerson DeltaV controllers and I/O subsystems
- Galvanic Isolation: Protects control system from field-side voltage transients and ground loops
- Proven Field Reliability: Widely deployed in oil & gas, chemical, power, and pharmaceutical process plants
- OEM Support: Eligible for Emerson lifecycle support, firmware updates, and warranty coverage
- Regulatory Compliance: Meets international safety and EMC standards for industrial control environments
Typical Applications
- Solenoid valve control in process piping systems
- Motor starter and contactor switching via DCS
- On/off control of pumps, fans, and actuators
- Alarm annunciator and indicator lamp outputs
- Discrete interlock and safety shutdown outputs
- Batch process step sequencing in pharmaceutical and food & beverage plants
System Compatibility
- DCS Platform: Emerson DeltaV (all generations supporting standard I/O cards)
- Controller Compatibility: DeltaV MD, MD Plus, MQ, PK, SD, SX controllers
- I/O Carrier: Standard 8-slot and 2-slot DeltaV I/O carriers
- Power Supply: DeltaV I/O bus powered (no separate field power required for module logic)
- Field Wiring: 24 VDC field supply required for output loads
- Not Compatible With: DeltaV CHARM I/O subsystem (requires CHARM-specific DO modules)
Selection Guide
Use the following criteria to confirm the KJ3001X1-BG1 is the correct module for your application:
- Step 1 — Output Type: Confirm discrete (on/off) output is required (not analog)
- Step 2 — Voltage: Confirm field devices operate at 24 VDC
- Step 3 — Isolation Requirement: Confirm isolated outputs are needed (vs. non-isolated DO modules)
- Step 4 — Channel Count: Verify the number of DO channels required matches this module’s specification
- Step 5 — Carrier Slot: Confirm available I/O carrier slots in your DeltaV cabinet
- Step 6 — Revision: Check your DeltaV system’s supported hardware revision list; BG1 is a later revision and may require updated firmware
- Step 7 — Spare vs. Active: For active replacement, ensure the module is commissioned and downloaded in DeltaV Explorer

Replacement & Compatibility FAQ
Q: Can I use a lower revision (e.g., BA1) to replace a BG1?
A: In most cases yes, as the electrical specification is identical. However, confirm with your DeltaV system’s hardware compatibility matrix, as some controller firmware versions may flag revision mismatches.
Q: Is the KJ3001X1-BG1 compatible with DeltaV S-series (CHARM)?
A: No. CHARM-based systems require CHARM DO modules (e.g., VE3008). The KJ3001X1-BG1 is for traditional DeltaV I/O carriers only.
Q: What is the difference between isolated and non-isolated DO modules?
A: Isolated modules provide galvanic separation between the control system and field wiring, protecting against ground loops and voltage transients. Non-isolated modules share a common ground with the field side.
Q: Can Konmask provide a test report or functional verification?
A: Yes, functional testing can be arranged for refurbished units. Contact us with your requirements.
Q: Do you offer volume discounts for multiple units?
A: Yes. Contact us via email or phone for volume pricing on orders of 3+ units.
