A safety related control system (SRCS) is the part of the machine control system that prevents a hazardous condition from occurring. It can be a separate dedicated system, or it may be integrated with the normal machine control system.
Its complexity will vary from a simple system, such as a guard door interlock switch and emergency stop switch connected in series to the control coil of a power contactor, to a compound system comprising of both simple and complex devices communicating through software and hardware.
Safety related control systems are designed to perform safety functions. The SRCS must continue to operate correctly under all foreseeable conditions.
