Emerson SLS1508 KJ2201X1-BA1 Smart Logic Solver

The Emerson SLS1508 KJ2201X1-BA1 Smart Logic Solver is a high-integrity safety logic solver module designed to meet the strict requirements of safety instrumented systems (SIS). Developed as part of Emerson’s DeltaV™ SIS platform, it provides advanced logic processing and seamless integration for critical process safety applications.

This module ensures reliability and performance for safety-critical processes in oil & gas, petrochemical, refining, and power generation industries. With TÜV certification up to SIL 3, the SLS1508 combines flexible logic control, redundant communication, and fail-safe operation to deliver the highest levels of functional safety.

Its robust construction, advanced diagnostics, and compact design allow operators to implement safety instrumented functions (SIFs) with confidence. It can be deployed for emergency shutdown systems (ESD), fire and gas detection systems (F&G), burner management, and other high-risk process automation applications.
