DeltaV I/O Solution – Emerson 12P4629X082 | CHARM Terminal Block Series
Where This Product Is Used
The Emerson 12P4629X082 CHARM Terminal Block is a field-side wiring interface designed for use within Emerson’s DeltaV™ CHARM (Characterization Module) I/O architecture. It is deployed in process automation and control environments where flexible, loop-powered field device termination is required without dedicated marshalling cabinets.
Typical installation sites include:
- Oil & gas upstream/midstream/downstream processing facilities
- Chemical and petrochemical plants requiring ISA-18.2 alarm management compliance
- Pharmaceutical manufacturing with FDA 21 CFR Part 11 audit trail requirements
- Power generation and utilities with high-density I/O demands
- Pulp, paper, and mining operations with distributed control architectures
- LNG terminals and offshore platforms requiring intrinsically safe field wiring

Why Engineers Specify This Model
- Electronic Marshalling Flexibility: CHARMs eliminate traditional hardwired marshalling, allowing any I/O type to be assigned to any field terminal — dramatically reducing engineering change-order costs during late-stage project modifications.
- Hot-Swap Capability: Individual CHARM modules can be inserted or removed under power without shutting down adjacent channels, minimizing process interruption during maintenance windows.
- Intrinsic Safety Integration: Certain CHARM variants support IS field devices natively, removing the need for external Zener barriers or galvanic isolators in Zone 1/Division 1 applications.
- Reduced Cabinet Footprint: High-density termination reduces panel space by up to 40% compared to conventional I/O marshalling, a critical advantage in brownfield retrofits.
- Lifecycle Continuity: As a genuine Emerson component, the 12P4629X082 ensures firmware compatibility and full DeltaV diagnostic visibility without third-party workarounds.
Complete System Bill of Materials
The 12P4629X082 CHARM Terminal Block operates as part of a broader DeltaV Electronic Marshalling assembly. A typical BOM for a CHARM I/O node includes:

- CHARM Carrier — 8-slot or 16-slot DIN rail carrier
- 12P4629X082 CHARM Terminal Block (this item)
- Individual CHARM Modules (AI, AO, DI, DO, HART, IS variants)
- DeltaV Controller (MD, MD Plus, or S-series)
- DeltaV Power Supply Module
- Field Junction Box / Multicore cable assembly

Application-Specific FAQ
Q: Is the 12P4629X082 compatible with all DeltaV CHARM carriers?
A: It is designed for use with Emerson’s standard CHARM carrier infrastructure. Confirm carrier revision compatibility with your DeltaV system version before ordering.
Q: Can this terminal block be used in SIL 2 safety loops?
A: CHARM-based I/O can support SIL-rated applications when used with appropriate SIS-certified CHARM modules and a validated safety logic solver. The terminal block itself is a passive wiring interface — SIL rating is determined at the loop level.
Q: Do you provide a warranty?
A: Yes. Konmask.com provides a 90-day functional warranty on all tested units. New surplus units carry the original manufacturer warranty where applicable.
Q: Can I return the part if it doesn’t fit my system?
A: We accept returns within 14 days for uninstalled, undamaged units. Contact support before returning.
Q: Do you offer expedited shipping for shutdown/turnaround emergencies?
A: Yes. Contact us directly at +0086 19859288691 for emergency sourcing and next-flight-out logistics options.
