Patent ID: 8188621

Claim:
A power delivery control product comprising: a safety isolation system having an input terminal and an output terminal and configured to control a power delivery from the input terminal to the output terminal; and a control module coupled to the safety isolation system and including: (a) safety switching components having redundant components enabling the safety switching components to operate in a redundant manner; (b) one or more input ports by which the control module is configured to receive redundant input signals indicative of a request for a cessation of the power delivery and is configured to receive a programmable controller signal indicating whether the cessation is acceptable; and (c) one or more output ports linked to the one or more input ports at least indirectly by the safety switching components, wherein the control module is configured to provide to the safety isolation system, via the one or more output ports, redundant control signals configured to cause the cessation when the redundant input signals are requesting the cessation, if the programmable controller signal indicates that the cessation is acceptable, whereby, in response to the redundant control signals, the cessation of the power delivery to the output terminal occurs.
