KL4101X1-BA1: Sourcing Guide for Emerson CHARM Carrier

Introduction: The Evolution of Process I/O

Over the past two decades, process automation has shifted from centralized marshalling cabinets to distributed, electronic marshalling. Engineers once wrestled with hundreds of home-run wires; today, modular I/O carriers like the Emerson KL4101X1-BA1 CHARM I/O Card Carrier simplify cabinet design and reduce footprint. For procurement teams, sourcing this carrier requires careful attention to hazardous area certifications and power specifications.

Product Overview

The KL4101X1-BA1 is a CHARM I/O Card Carrier from Emerson. It provides the physical and electrical interface for CHARM I/O cards in DeltaV systems. The carrier is designed for installation in hazardous locations, as evidenced by its multiple certifications. It is not user-serviceable and requires no calibration.

Spec Analysis: Power and Environmental Ratings

When evaluating the KL4101X1-BA1 for your bill of materials, verify these parameters against your site requirements:

• Input Power: 24 VDC at 12 A
• Output Power to CHARMs: 6.3 VDC at 3.25 A
• Ambient Temperature: -40 °C to +70 °C
• Shock: 10g ½ Sinewave for 11 msec
• Vibration: 1 mm Peak to Peak from 2 to 13.2 Hz; 0.7g from 13.2 to 150 Hz
• Airborne Contaminants: ISA-S71.04–1985 Class G3
• Relative Humidity: 5 to 95% Non-Condensing

These ratings confirm the carrier is suitable for harsh industrial environments. Note that the unit cannot be removed or inserted with system power energized unless the area is known to be non-hazardous.

Hazardous Area Certifications

The KL4101X1-BA1 carries the following certifications, which are critical for procurement in classified areas:

• II 3G Ex ec IIC Gc
• FM19ATEX0173U
• IECEx FMG 19.0019U
• FM21UKEX0017U
• CL. I Div. 2 GP. A,B,C,D
• CL. I Zone 2 AEx/Ex ec IIC Gc
• FM17CA0145U
• FM17US0286U

Always confirm that the certification matches your installation’s classification. The ‘U’ suffix on some certificates indicates that the component is suitable for use in hazardous locations when installed in an approved enclosure.

Application Scenarios and Compatibility

This carrier is used in DeltaV electronic marshalling cabinets, typically in oil and gas, chemical, and pharmaceutical plants. It interfaces with CHARM I/O cards, which handle analog and discrete signals. When replacing or upgrading, ensure the carrier’s power and communication backplane match your existing DeltaV system. Because the carrier is a passive component, compatibility is primarily mechanical and electrical.

Procurement Guidelines: OEM vs Aftermarket

For critical infrastructure, genuine OEM parts are recommended to maintain certification validity. Aftermarket equivalents may be available, but they must be verified for form, fit, and function. PLCXpert provides genuine OEM and equivalent parts with verified specifications, helping you avoid downtime and compliance risks. Our team offers expert technical consultation to ensure you select the correct carrier for your application.
