- KJ3222X1-BA1 – Emerson DeltaV AI module with enhanced diagnostics
- KJ3224X1-BA1 – Emerson DeltaV 4–20 mA AI, 16-channel variant for higher density applications
- KJ3231X1-BA1 – Emerson DeltaV Thermocouple/RTD input module (for temperature signal migration)
- VE3008 – Emerson DeltaV CHARM I/O analog input characterization module (next-gen platform)
- ABB AI810 / AI820 – Cross-brand equivalent for 4–20 mA HART AI in S800 I/O systems (requires gateway)
- Honeywell MC-TAIH02 – Functional equivalent in Honeywell TDC/Experion systems (migration project use)
Note: Cross-brand replacements require system integration assessment. Contact Konmask for compatibility verification.
Why Choose the Original Model
- Seamless DeltaV Integration: Plug-and-play with existing DeltaV S-Series I/O carriers — no reconfiguration of the controller required.
- HART Pass-Through: Full HART communication support enables remote diagnostics and device configuration without additional hardware.
- Proven Reliability: Widely deployed in critical process industries with a long field track record.
- Emerson Lifecycle Support: Covered under Emerson’s DeltaV lifecycle policy with available firmware updates and technical support.
- Reduced Commissioning Risk: Using the original part number eliminates compatibility uncertainty during maintenance or expansion projects.
Typical Applications
- Oil & gas upstream/downstream process monitoring
- Chemical plant distributed control systems (DCS)
- Power generation boiler and turbine control loops
- Pharmaceutical batch process automation
- Water treatment and municipal utility SCADA integration
- Pulp & paper mill process control
System Compatibility
- Compatible DCS Platform: Emerson DeltaV S-Series (v10.3 and above recommended)
- I/O Carrier: KJ3001X1-BA1 or equivalent DeltaV 8-slot I/O carrier
- Controller Compatibility: DeltaV MD, MD Plus, MQ, PK controllers
- Redundancy: Supports simplex configuration; check carrier for redundant I/O support
- HART Devices: Compatible with HART 5, 6, and 7 field instruments
Selection Guide
Use the following criteria to determine if the KJ3225X1-BA1 is the right module for your application:
- Signal Type: Required for 4–20 mA analog inputs with HART communication. If your signals are thermocouple or RTD, consider KJ3231X1-BA1 instead.
- Channel Count: 8 channels per module. For higher density, evaluate KJ3224X1-BA1 (16-channel).
- Platform: Designed exclusively for Emerson DeltaV S-Series. Not compatible with DeltaV M-Series or third-party DCS without a gateway.
- HART Requirement: If HART is not required, KJ3221X1-BA1 offers a cost-effective alternative.
- Spare Parts Strategy: For long-term MRO stocking, confirm EOL status with Emerson or source certified refurbished units through authorized distributors like Konmask.

Replacement & Compatibility FAQ
Q: Can KJ3225X1-BA1 replace KJ3221X1-BA1 directly?
A: Yes, in most cases. The KJ3225X1-BA1 adds HART capability over the KJ3221X1-BA1. Physical form factor and I/O carrier compatibility are identical. Verify DeltaV version supports HART on that carrier slot.
Q: Is 12P4174X032 the same as KJ3225X1-BA1?
A: Yes. 12P4174X032 is the Emerson internal manufacturing part number; KJ3225X1-BA1 is the commercial ordering part number. They refer to the same hardware revision.
Q: Can I use this module in a DeltaV M-Series system?
A: No. The KJ3225X1-BA1 is designed for the DeltaV S-Series I/O architecture. M-Series uses a different I/O carrier and bus standard.
Q: Do you supply certified refurbished units?
A: Yes. Konmask offers both new and certified refurbished KJ3225X1-BA1 modules. Refurbished units include inspection reports and a 90-day warranty.
Q: What is the warranty on new units?
A: New units carry the original Emerson manufacturer warranty. Contact us for current warranty terms applicable to your region.
