・電源遮断装置。[Claims for Utility Model Registration] A device for generating an alarm and cutting off power to the relay when an abnormality occurs in an electronic circuit including a load operated via a relay driven by input voltage. It has a pair of input terminals, the input voltage is applied to one input terminal, and at least a part of the voltage between the terminals of the load is applied to the other input terminal, and the input terminal of the pair of input terminals is an abnormality detection means configured to detect an abnormality by not generating an output when the states of voltages applied to the terminals are the same, and generating an output only when they are different; and an output of the abnormality detection means. Alarm generation and power cutoff in an electronic circuit, characterized in that the electronic circuit is equipped with an alarm means that generates an alarm in response to the abnormality detection means, and a power cutoff means that cuts off energization to the relay in response to the output of the abnormality detection means. Device.
