Compatible Replacement & Equivalent Models
When the SP6402 is discontinued, obsolete, or unavailable, the following models may serve as functional replacements depending on system revision and carrier compatibility. Always verify firmware and carrier compatibility before substitution.
| Replacement Model | Type | Compatibility Notes |
|---|---|---|
| EMERSON KJ3221X1-BA1 | Analog Output, 8-ch | DeltaV S-series; verify carrier revision |
| EMERSON VE4005S2T2B4 | Analog Output | DeltaV M-series; same signal range |
| EMERSON KJ3221X1-BB1 | Analog Output, HART | Upgraded HART 7 support |
| Honeywell MC-TAOY22 | Analog Output (cross-brand) | Requires signal conditioning adapter |
| ABB AI810 | Analog Output (cross-brand) | Different bus architecture; not plug-compatible |
Note: Cross-brand replacements require engineering review. Konmask recommends OEM-equivalent substitution wherever possible.
Why Choose the Original Model
- Guaranteed DeltaV Compatibility: Native integration with DeltaV controllers, carriers, and configuration tools (DeltaV Explorer, Control Studio).
- HART Pass-Through: Full HART 5/7 communication for field device diagnostics without additional hardware.
- Proven Field Reliability: Deployed in thousands of process plants globally with documented MTBF performance.
- Simplified Spare Parts Management: Single SKU covers multiple loop types — reduces warehouse complexity.
- OEM Firmware Support: Eligible for Emerson firmware updates and lifecycle support programs.
Typical Applications
- Oil & Gas: Control valve positioner output, flow control loops, pressure regulation in upstream/downstream facilities.
- Chemical Processing: Reactor temperature and feed rate control via 4–20 mA to I/P converters.
- Power Generation: Turbine governor signal output, boiler feed water control.
- Pharmaceutical: Bioreactor agitation speed and temperature setpoint output in FDA-regulated environments.
- Water & Wastewater: Pump speed reference output to VFDs, dosing pump control.
- Pulp & Paper: Consistency control, headbox pressure output loops.
System Compatibility
| DeltaV Platform | Compatible | Notes |
|---|---|---|
| DeltaV M-Series Controller | ✅ Yes | Standard carrier required |
| DeltaV S-Series Controller | ✅ Yes | Verify carrier revision ≥ Rev C |
| DeltaV SIS (Safety) | ❌ No | Use SIS-certified I/O modules |
| DeltaV Compact Controller | ⚠️ Check | Confirm I/O bus version |
| DeltaV Virtual I/O | ❌ No | Software simulation only |
Selection Guide
Use the following criteria to confirm the SP6402 is the right module for your application:
- ✅ Output type required: 4–20 mA analog (not discrete or digital)
- ✅ Channel count: Up to 8 independent output channels needed
- ✅ HART communication: Field device diagnostics via HART required
- ✅ Platform: Emerson DeltaV M-Series or S-Series DCS
- ✅ Environment: Non-SIS, standard process control zone
- ⚠️ If SIL-rated output is required: Specify EMERSON SIS-certified analog output module instead
- ⚠️ If >8 channels needed: Add additional SP6402 modules on the same carrier bus
Quality Assurance & Sourcing

Replacement & Compatibility FAQ
Q: Can I replace SP6402 with a newer Emerson analog output module?
A: Yes, in most cases. Newer models like KJ3221X1-BB1 are backward-compatible with DeltaV M/S-Series carriers, but firmware and carrier revision must be verified before hot-swap.
Q: Is SP6402 compatible with HART 7 field devices?
A: The SP6402 supports HART 5 natively. HART 7 devices will communicate in HART 5 fallback mode. For full HART 7 support, consider the KJ3221X1-BB1 upgrade.
Q: Can SP6402 be used in a SIL 2 safety loop?
A: No. The SP6402 is not SIL-certified. For safety instrumented systems, use Emerson’s DeltaV SIS-certified I/O modules.
Q: What is the lead time for SP6402?
A: In-stock units ship within 3–5 business days. For bulk orders, contact Konmask for confirmed lead time.
Q: Do you provide a certificate of conformance (CoC)?
A: Yes. CoC, test reports, and traceability documentation are available upon request for all orders.
Q: Can Konmask source discontinued SP6402 units?
A: Yes. Konmask specializes in sourcing legacy and obsolete Emerson DeltaV modules through verified supply channels.
