Emerson KL2101X1-BA1 Provox IO Interface Module

Global 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), 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 Performance

Input Power: 24 VDC at 2 A, compatible with standard industrial power supplies and supporting 

stable operation of connected components.

Output Power: 6.3 VDC at 3.25 A, delivering reliable power to field devices and peripheral modules 

while minimizing energy loss.

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 stressors.

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 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.

Flexible Power & System Integration

Dual Power Channels: Separated input and output power paths prevent cross-interference, ensuring stable performance of both the card itself and connected field devices.

DeltaV™ Ecosystem Compatibility: Designed exclusively for Emerson’s DeltaV™ CHARM I/O Subsystem and S-Series hardware, ensuring perfect integration with existing control architectures.

High Compatibility with Field Devices: Supports a wide range of industrial sensors and actuators, 

serving as a versatile interface for diverse signal types in process control.

No User-Serviceable Parts: Sealed design eliminates the need for on-site disassembly, calibration, or component replacement, reducing maintenance workload and downtime.

Industrial-Grade Durability: Reinforced construction withstands harsh environmental conditions 

(shock, vibration, contaminants), ensuring consistent performance over an extended service life.
