Emerson KL4101X1-BA1 DeltaV CIOC CHARM I/O Card Carrier

Product Overview

The Emerson KL4101X1-BA1 operates as a high-density CHARM I/O Card Carrier within the DeltaV Distributed I/O Characterization (CIOC) architecture. This structural backplane framework serves as the physical and electrical foundation for Electronic Marshalling, accepting individual, single-channel CHARM modules. The carrier manages the high-amperage redundant power feeds from primary system bulk supplies and distributes regulated voltage tracks to every plugged component. By mapping field wiring directly to software channels over a unified bus, this unit replaces traditional physical cross-marshalling terminal strips. We guarantee this CHARM I/O card carrier arrives in 100% brand new, original factory-sealed condition.

Technical Specifications

Engineering Advantages

• Continuous Redundant Power Pathing: The carrier integrates dual, independent 24 VDC power traces rated at 12 A. This design accommodates two separate power supply feeds simultaneously, allowing the backplane to keep field instrumentation active even during a catastrophic main utility grid failure.

• Low-Impedance Power Down-Stepping: The heavy-duty busbars step internal voltage down to a clean, stable 6.3 VDC at 3250 mA across the module slots. This low-impedance layout protects delicate CHARM microprocessors from ground loops and prevents voltage sags when driving heavy field relays or loop transmitters.

• High-Density Cabinet Footprint Elimination: Weighing only 0.77 lbs, the slim profile mounts directly onto standard industrial DIN rails. The architecture packs dozens of individual I/O channels horizontally, saving critical wall space inside crowded marine enclosures or remote instrument enclosures (RIEs).

• High-Frequency Electromagnetic Isolation: The integrated multi-layer printed backplane incorporates extensive copper grounding sheets. These ground structures block industrial electromagnetic interference (EMI) originating from nearby variable frequency drives (VFDs) and heavy switchgear, preventing data bus corruption or signal distortion.

FAQs

• Does this KL4101X1-BA1 carrier arrive in its original factory box?

  Yes. We deliver this hardware assembly exclusively as a 100% brand new, factory-original component. The carrier remains sealed within its untouched Emerson anti-static protective wrapping inside the original manufacturer box, preserving all official serial barcodes, quality inspector marks, and security seals.

• Can I replace this carrier baseplate while the system is powered and running?

  No. While individual CHARM modules allow hot-swapping, pulling or installing a primary baseplate carrier like the KL4101X1-BA1 breaks the core backplane power lines and disconnects multiple active field loops instantly. You must completely isolate the 12 A, 24 VDC feeder lines before mounting or unmounting this unit.

• How should I wire the dual input power terminals to ensure true redundancy?

  Connect the primary input terminals to an independent bulk 24 VDC power supply module and route the secondary input terminals to a separate backup battery system or secondary power phase. This separate routing ensures that a single supply failure cannot disable both power traces within the carrier.

• What is the advantage of using this carrier over traditional PLC racks?

  This carrier enables Electronic Marshalling. Instead of running dedicated multi-core cables to fixed multi-channel analog or digital cards, you place any CHARM type (AI, AO, DI, DO) onto any slot on this carrier. The DeltaV system software then automatically detects and maps the channel type, dropping engineering, drawing, and panel fabrication costs by up to 40%.
