Functions and Applications
-
Redundant Safety: Provides dual circuit paths (A–B and A–C). If one circuit fails, the other continues to operate, ensuring continuous control system operation.
-
Hazardous Area Compatibility: Specifically designed for flammable and explosive environments, featuring intrinsic safety to prevent ignition of surrounding combustible gases.
-
System Integration: Seamlessly integrates into the Emerson DeltaV Distributed Control System (DCS), simplifying process control wiring and maintenance.
