Product Introduction

The Emerson KJ2201X1-BA1 DeltaV Logic Solver is a critical component of Emerson’s DeltaV SIS™ (Safety Instrumented System) process safety system. Designed as a smart SIS Logic Solver, it integrates predictive field intelligence to enhance the availability and reliability of safety instrumented functions (SIFs). This SIL 3-rated device is engineered for flexible deployment, seamless compliance with IEC 61511, and scalability to fit applications ranging from isolated wellheads to large-scale ESD/fire and gas systems.

 

• World’s First Smart SIS Logic Solver: Utilizes HART protocol for real-time diagnostics, reducing spurious trips and lifecycle costs.
• Redundant Architecture: Features dual CPUs and parallel operation for bumpless failover, ensuring uninterrupted safety functions.
• Cybersecurity Ready: Certified to ISA System Security Assurance (SSA) Level 1 per IEC 62443.
