ABSTRACT:
The present invention relates to an intermediate module capable of being implemented in conjunction with a safety isolation system, as well as a control system employing such an intermediate module and related operational method. In one embodiment, the intermediate module includes a first input terminal capable of receiving a first signal from an additional device that is at least one of the safety isolation system and another device, and a first output terminal capable of providing a second signal to a controlled device. The intermediate module additionally includes at least one safety relay circuit that receives at least one of the first signal and a first intermediate signal based upon the first signal, and that generates in response at least one of the second signal and a second intermediate signal upon which the second signal is based. The safety relay circuit includes at least one redundant circuit component.
