分けを容易に行えるようにしたものである。Generates a cutting instruction signal based on an external control signal,
An abnormal state in which a disconnection instruction signal is not generated even after a predetermined period of time has elapsed from the time when the control signal was input, in a power input/disconnection device that applies this signal to the power switch operating means of a controlled device to turn the power switch into a disconnected state. By detecting the abnormal condition in which the power switch is not disconnected even after a predetermined period of time has elapsed from the time when the disconnection instruction signal is input to the power switch operating means, it is possible to quickly start executing the process for the abnormal condition when the power is disconnected. The system is designed to make it easier to isolate the location where a failure occurs.

1. This is a conventional example device for turning on and off using 1. When a carrier wave 10 for data transmission is sent out from a remote location, a carrier-on signal 11 output from the modulation/demodulation device 3 is turned on. When this signal is detected by the power-on instruction detection circuit 1a for a certain period of time, the power-on instruction detection signal 12 is turned on and input to the power-on/off control circuit 1b. When the power-on instruction detection signal 12 is inputted from the power-on/off control circuit 1b, the power-on instruction signal 13 is output in the power-on instruction state, and the controlled device 2 is powered on, completing the power-on operation. Thereafter, when a series of data processing is completed in the controlled device 2, this device self-determines whether or not the power can be cut off, and it is determined that the power can be cut off, and the cut-off instruction signal 16 is turned on. When this signal is detected by the disconnection instruction detection circuit 1c for a certain period of time, the disconnection instruction detection signal 15 is turned on and the power to the controlled device 2 is cut off.
