Emerson KL2102X1-BA1 WIRELESS I/O CARD

Certification Compliance: Meets 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), and UKEX (FM21UKEX0017U) standards, approved for use in 

hazardous atmospheres.

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

ideal for oil & gas, chemical, and petrochemical sites with flammable gases/vapors.

Power Requirements

Input Power: 24 VDC (two options: 400 mA and 100 mA), compatible with standard industrial power supplies and supporting flexible system power configuration.

Output Power: Optimized for wireless signal transmission and field device power supply, balancing 

energy efficiency and performance.

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

and high-heat (e.g., refineries) environments.

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), suitable for rugged on-site conditions.

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

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

Robust Explosion Protection Design

Certified for Hazardous Zones: Multi-standard certifications eliminate compatibility barriers for 

international projects, ensuring compliance with local safety regulations without additional 

modifications.

Safe Installation/Removal: Requires field power disconnection before removal/connection; cannot 

be hot-swapped in hazardous areas unless confirmed non-hazardous, minimizing ignition risks.

Wide Environmental Suitability

Extreme Temperature Operation: -40 °C to +70 °C range covers most industrial scenarios, from 

arctic oil fields to desert refineries, reducing the need for specialized temperature control 

equipment.

Rugged Mechanical Build: Shock and vibration resistance ensures stable performance in high-

impact environments (e.g., pipeline monitoring, mobile equipment) and harsh industrial sites with 

mechanical stress.

DeltaV™ Compatibility: Designed for Emerson’s DeltaV™ Electronic Marshalling Digital Automation System (CHARM I/O Subsystem), integrating seamlessly with existing control architectures.

Rotary Keying System: Ensures precise compatibility between I/O cards and terminal blocks post-

installation, preventing misconnection and enhancing system reliability.

Low Maintenance: No user-serviceable parts, eliminating the need for on-site calibration or 

disassembly, reducing operational downtime and maintenance costs.
