电力供给控制装置，及可程式逻辑控制器;POWER SUPPLY CONTROL DEVICE AND PROGRAMMABLE LOGIC CONTROLLER

摘要

本发明提供一种电力供给控制装置，具备：电源输入端子；将电力输出至负载的输出电路；并联连接于电源输入端子与输出电路之间的复数个电力遮断电路；及各别地控制复数个电力遮断电路的控制电路。各电力遮断电路具有串联连接于电源输入端子与输出电路之间的遮断电路及开关元件。遮断电路于从控制电路接受到通过许可信号时使电力通过，而于未接受到通过许可信号时遮断电力的通过。开关元件藉由控制电路而受导通/切断控制。控制电路将复数个电力遮断电路之中的任一个设定为诊断对象电路时，停止对于诊断对象电路之遮断电路供给通过许可信号，并且将诊断对象电路之开关元件切断。; and when the cut off circuit is not receiving the passing allowable signal, the cut off circuit cut off the passing of the electric power. The switching element is on/off controlled by the control circuit. When the control circuit performs a setting of any one of the plurality of power cut off circuits, the control circuit stops the supply of the passing allowable signal to the cut off circuit of the object circuit to be diagnosed and turns off the switching element of the object circuit to be diagnosed.
