Emerson SLS1508 KJ2201X1-BA1 | SIL3 Certified Logic Solver

Product Description

The Emerson SLS1508 (KJ2201X1-BA1 + KJ2201X1-HA1) is a robust Safety Instrumented System (SIS) Logic Solver designed for mission-critical applications in industries such as power generation, oil & gas, and chemical processing. Built with Triple Modular Redundancy (TMR), it ensures 99.9999% reliability, providing the highest level of safety for emergency shutdowns, fire and gas protection, and process interlocks.

The KJ2201X1-BA1 module supports 16 configurable safety channels, capable of handling both analog (4–20 mA/HART) and digital (NAMUR/DI) field devices. With a 50 ms execution time, it offers rapid response during emergencies, ensuring that critical systems operate with minimal delay. Its integration with DeltaV systems makes it an ideal choice for users who require a reliable and highly responsive safety solution.

This module is built for safety-critical environments and is SIL3 certified according to IEC 61508 standards, making it suitable for demanding applications that require hardware fault tolerance and redundant communication.
