Overview
ABB AC800F is a high-performance, high-availability controller that forms the core of ABB’s distributed control systems. It uniquely combines standard process control with safety instrumented system (SIS) functions in a single platform, certified for SIL 2 and SIL 3 applications according to IEC 61508 and IEC 61511 standards. This dual capability makes it ideal for integrated safety and process control applications.
