Emerson SLS1508 KJ2201X1-BA1 Smart Logic Solver

Global Compliance: Meets ATEX (II 3G EEx nA IIC T4, Nemko No. 02ATEX431U), FM (Class I Div. 2 

Groups A-D, Hazardous Location, Temperature Rating T4), and TÜV NORD (IEC 61508:2000 SIL 3 

Capability) 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 Requirements

Input Power: 24 VDC at 1 A, compatible with standard industrial power supplies and supporting 

redundant power configurations for uninterrupted operation.

Field Power: Maximum 4 A output, providing sufficient power for connected field sensors, actuators, and peripheral devices in safety loops.

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, 5–16 Hz; 0.5g, 16–150 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.

SIL 3-Certified Safety Performance

SIL 3 Capability: Certified to IEC 61508:2000 SIL 3, enabling its use in high-demand safety 

instrumented functions (SIFs) where failure could lead to catastrophic consequences (e.g., 

emergency shutdown, fire & gas protection).

Non-Incendive Design (EEx nA): Prevents ignition of flammable atmospheres in hazardous zones, 

aligning with strict safety requirements for explosive environments.

Robust Reliability & Low Maintenance

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

Industrial-Grade Durability: Reinforced construction withstands shock, vibration, and harsh 

environmental contaminants, ensuring long-term stable operation in demanding conditions.

DeltaV™ SIS Compatibility: Designed exclusively for Emerson’s DeltaV™ Scalable Process System 

and Safety Instrumented System, integrating seamlessly with existing DeltaV™ hardware and 

software for unified control and monitoring.

Simplified Deployment: Compliant with DeltaV™ installation guidelines (12P2046, "DeltaV™ Scalable Process System Zone 2 Installation Instructions"), facilitating smooth integration into new or 

existing safety systems.
