Emerson 12P4627X072 – CHARM Terminal Block | DeltaV CHARMs Electronic Marshalling Platform
Engineering Background: The DeltaV CHARMs (Characterization Modules) Electronic Marshalling platform was developed by Emerson to eliminate the traditional hardwired marshalling cabinet, dramatically reducing engineering hours and enabling loop-by-loop commissioning. The CHARM Terminal Block is the foundational field-wiring interface within this architecture — it provides the physical connection point between field instrument cables and the CHARM characterization module seated above it.
Product Positioning: The Emerson 12P4627X072 is a factory-original CHARM Terminal Block designed for use within the DeltaV Electronic Marshalling system. It is specified by process automation engineers in greenfield DCS installations, brownfield expansions, and I/O cabinet retrofits where loop flexibility and reduced wiring complexity are critical project requirements. Konmask.com supplies this part with full traceability for MRO, capital project, and emergency replacement procurement.

Proven Application Environments
- Oil & Gas Processing: Upstream wellhead RTU panels, midstream compressor station DCS cabinets, and downstream refinery control rooms where loop-by-loop commissioning reduces turnaround time.
- Chemical & Petrochemical Plants: Continuous process units requiring high-density I/O marshalling with intrinsic safety or HART pass-through capability.
- Power Generation: Combined-cycle plant BOP (Balance of Plant) DCS expansions integrating DeltaV CHARMs into existing marshalling rooms.
- Pharmaceutical & Life Sciences: FDA-regulated batch process systems where validated DeltaV platforms require OEM-original replacement parts to maintain system qualification.
- Water & Wastewater: Large municipal SCADA/DCS hybrid systems migrating from traditional marshalling to electronic marshalling for reduced cabinet footprint.
- Pulp & Paper / Mining: Harsh-environment process areas where robust terminal block reliability is essential for continuous operation.
Engineering Advantages
- Zero-Marshalling Architecture: Eliminates cross-wiring between field junction boxes and I/O cards — each CHARM Terminal Block connects directly to its assigned CHARM module, reducing wiring errors and engineering rework.
- Hot-Swap Capable: CHARM modules can be inserted and removed from the terminal block without powering down the carrier, enabling live maintenance and loop testing.
- Loop-by-Loop Commissioning: Field wiring can be terminated and tested independently per loop, decoupling commissioning from cabinet completion milestones.
- OEM Original Part: Factory-manufactured to Emerson’s exact dimensional and electrical tolerances — ensures full compatibility with CHARM carriers and CIOC controllers without field modification.
- Reduced Cabinet Footprint: High-density CHARM architecture allows more I/O points per cabinet U-height compared to traditional marshalling, lowering civil and electrical installation costs.
- HART Transparency: Terminal block design preserves HART signal integrity for asset management and diagnostics via AMS Device Manager.
System Architecture & Signal Flow
In a DeltaV CHARMs system, the signal flow from field to controller follows this path:
- Field Instrument → cable routed to marshalling cabinet
- CHARM Terminal Block (12P4627X072) → field wires terminated at screw terminals; provides the physical anchor point on the CHARM carrier
- CHARM Module → plugs into the terminal block; performs signal characterization (AI 4-20mA, DI 24VDC, AO, etc.)
- CHARM Carrier / CIOC → aggregates multiple CHARMs; communicates to DeltaV controller via high-speed backplane
- DeltaV Controller (MD/MD Plus/SD) → executes control strategy; data available on DeltaV network
The terminal block is the only component in this chain that remains in place during CHARM module replacement, preserving field wiring integrity during maintenance events.

Technical FAQ
Q: Is the 12P4627X072 compatible with all CHARM module types?
A: The CHARM Terminal Block is designed for use with the standard CHARM carrier system. Compatibility depends on the specific CHARM module type (AI, AO, DI, DO, HART). Confirm your CHARM module part number with our team before ordering to ensure dimensional and electrical compatibility.
Q: Can I replace just the terminal block without replacing the CHARM module?
A: Yes. The terminal block and CHARM module are separate, independently replaceable components. Field wiring remains terminated on the block while the CHARM module is swapped — this is a key design advantage of the CHARMs architecture.
Q: What is the difference between 12P4627X072 and similar Emerson CHARM terminal block part numbers?
A: Emerson uses revision suffixes (X072, X082, etc.) to denote hardware revisions. While functionally similar, always specify the exact part number required by your system’s BOM or Emerson’s compatibility matrix to avoid revision mismatches in validated systems.
Q: Do you supply documentation for FDA/GMP-regulated facilities?
A: Yes. Certificate of conformance, material traceability records, and supplier qualification documentation are available upon request for pharmaceutical and life sciences customers.
Q: What is the lead time for this part?
A: Lead time depends on current stock levels. Contact us for real-time availability. Emergency/expedite orders are accommodated where stock permits.
