Emerson KL4201X1-BA1 CHARM BASEPLATE TERMINALS

Global Certifications: Complies with ATEX (II 3G Ex ec IIC Gc), IECEx (FMG 19.0019U), FM (Class I Div. 

2 Groups A-D, Zone 2 AEx/Ex ec IIC Gc), UKEX (FM21UKEX0017U), Canadian (FM17CA0145U), and 

US (FM17US0286U) standards.

Hazardous Location Rating: Approved for Class I, Division 2, Groups A-D and Zone 2 environments, 

suitable for sites with flammable gases/vapors (e.g., oil & gas, chemical plants).

Power Distribution Capacity

CHARM Bus Power: 6.3 VDC at 4 A, delivering stable power to connected CHARM I/O modules for 

reliable signal processing.

Field Circuit Power: 24 VDC at 10 A, supporting high-power field devices and ensuring sufficient 

power supply for multiple connected components.

Temperature Range: -40 °C to +70 °C, operating reliably in extreme cold (e.g., arctic pipelines) and 

high-heat (e.g., refineries) conditions.

Mechanical Resilience: Withstands 10g ½ sinewave shock (11 ms duration) and vibration (1 mm 

peak-to-peak, 2–13.2 Hz; 0.7g, 13.2–150 Hz), enduring rugged industrial site conditions.

Contaminant & Humidity Resistance: Meets ISA-S71.04–1985 Class G3 for airborne contaminants 

and operates in 5–95% RH (non-condensing), resisting corrosive gases and moisture.

Robust Safety & Compliance

Multi-Standard Approval: Global certifications eliminate regional compliance barriers, enabling 

seamless deployment in international projects without additional modifications.

Safe Installation/Removal: Cannot be hot-swapped with system power energized in hazardous areas (unless confirmed non-hazardous), minimizing ignition risks and ensuring operational safety.

High-Capacity Power Distribution

Dual Power Channels: Separated CHARM bus power and field circuit power prevent cross-

interference, ensuring stable operation of both control modules and field devices.

High Current Handling: 10 A field power capacity supports multiple high-demand devices, reducing the need for additional power distribution units and simplifying system design.

DeltaV™ CHARM Compatibility: Designed exclusively for Emerson’s DeltaV™ Electronic 

Marshalling Digital Automation System, ensuring perfect integration with CHARM I/O modules and 

S-Series hardware.

Low Maintenance Design: No user-serviceable parts and no calibration required, reducing on-site 

maintenance workload and minimizing operational downtime.

Rugged Construction: Industrial-grade materials and reinforced design enhance durability, 

withstanding harsh environmental stressors (shock, vibration, contaminants) for long-term 

reliability.
