Compatible Replacement & Equivalent Models
When the 12P4628X102 is discontinued, long lead-time, or cost-prohibitive, the following models may serve as functional equivalents or direct replacements. Always validate electrical and mechanical compatibility before installation.
- Emerson 12P4628X112 — Revised suffix variant; verify revision compatibility with your CIOC carrier firmware
- Emerson 12P4628X122 — Alternative suffix; check terminal pitch and wiring scheme
- Emerson KJ3221X1-BA1 — CHARM I/O Terminal Block (AI/AO type); confirm signal type match
- Emerson KJ3222X1-BA1 — DI/DO CHARM Terminal Block equivalent candidate
- Third-party DIN-rail terminal blocks — Phoenix Contact, Weidmüller, or Wago equivalents may be mechanically compatible; electrical interface must be independently validated
⚠ Disclaimer: Konmask.com provides this cross-reference for reference only. Compatibility must be confirmed by a qualified engineer against your system’s BOM and Emerson documentation.
Why Choose the Original Model
- Guaranteed Fit: Factory-engineered to snap precisely onto Emerson CIOC/CIOCP carriers — no field modification required
- Signal Integrity: Designed and tested to Emerson’s DeltaV signal specifications, minimizing noise and wiring errors
- Lifecycle Support: Emerson provides firmware, documentation, and spare parts support for original part numbers
- Audit & Compliance: Original part numbers simplify FAT/SAT documentation, SIL validation, and regulatory audits
- Reduced Risk: Eliminates compatibility unknowns introduced by third-party substitutes in safety-critical loops
Typical Applications
- Oil & Gas — upstream wellhead control, midstream pipeline SCADA, downstream refinery DCS
- Chemical & Petrochemical — reactor monitoring, batch process control
- Power Generation — turbine control, boiler management systems
- Pharmaceutical — FDA-regulated manufacturing with validated DeltaV systems
- Pulp & Paper / Mining — continuous process automation with marshalling-free I/O
- Water & Wastewater — remote I/O termination in distributed control architectures
System Compatibility
- Platform: Emerson DeltaV™ Distributed Control System (DCS)
- I/O Architecture: CHARM (Characterization Module) I/O — marshalling-free, intrinsically safe capable
- Compatible Carriers: CIOC (CHARM I/O Card), CIOCP (CHARM I/O Card with Power)
- DeltaV Version: Compatible with DeltaV v11.3 and later (verify with Emerson for specific revision)
- Communication: Integrates with DeltaV Electronic Marshalling architecture
- Hazardous Area: Consult Emerson for IS/Ex-rated CHARM terminal block variants
Selection Guide
Use the following criteria to confirm the 12P4628X102 is the correct terminal block for your application:
- Step 1 — Identify your CHARM type: AI (Analog Input), AO (Analog Output), DI (Discrete Input), DO (Discrete Output), or HART. The terminal block must match the CHARM signal type.
- Step 2 — Confirm carrier model: Verify your CIOC or CIOCP carrier part number. Terminal block mechanical fit depends on carrier generation.
- Step 3 — Check field wiring requirements: Number of conductors, wire gauge (AWG), and shielding requirements must match terminal block specifications.
- Step 4 — Review revision suffix: The suffix X102 indicates a specific hardware revision. Confirm compatibility with your installed base revision level.
- Step 5 — Hazardous area classification: If installing in Zone 1/2 or Div 1/2 areas, confirm the terminal block carries the required Ex/IS certification.

Replacement & Compatibility FAQ
Q: Can I use a third-party terminal block as a direct replacement for the 12P4628X102?
A: Mechanically similar DIN-rail terminal blocks may fit, but the electrical interface, terminal pitch, and CHARM signal routing are proprietary to Emerson. Third-party substitution requires engineering validation and is not recommended for safety-instrumented loops.
Q: What is the difference between 12P4628X102 and 12P4628X112?
A: The suffix (X102 vs X112) typically denotes a hardware revision. Functional differences are minor, but firmware and carrier compatibility should be verified with Emerson’s revision compatibility matrix.
Q: Is the 12P4628X102 still in production?
A: Emerson periodically revises CHARM components. Contact Konmask.com or Emerson directly to confirm current production status and recommended replacement if discontinued.
Q: Can this terminal block be used with non-DeltaV systems?
A: The 12P4628X102 is designed specifically for the DeltaV CHARM I/O architecture. Use with other DCS platforms is not supported without significant engineering adaptation.
Q: Do you provide certificates of conformance (CoC)?
A: Yes. CoC and material traceability documentation are available upon request for new and surplus stock.
