The switch 13 operates to switch output terminals e and f of different voltages of the voltage setting circuit 12.

This diode 16 is connected to the cathode side of 6.
The anode side of is connected to the terminal f of the switch 13. Terminal d of switch 13 is connected to first relay 1

is applied to the relay 14 of. When this relay 14 is on, the voltage is input to the second relay 15 on the monitored control device 11 side, and the output voltage V 0 between output terminals b and c becomes +24V. On the other hand, the first relay 14
When the relay 14 is off, the remote monitoring control device 10 side and the monitored control device 11 side are opened, so no voltage is applied to the second relay 15, and the output voltage V0 becomes 0V. Become. second relay 15
operates at +12V or more, so in this case, it will be activated when the first relay 14 is on, and will not be activated when this relay 14 is off, and normal remote control operation will be performed.

せず、被監視制御装置が制御することはない。 Next, when the switch 13 is turned down, the terminals d and f are connected, so the +24V control output signal input to the input terminal a is applied to the first relay 14 via the Zener diode 16. Ru. Since the Zener voltage of the Zener diode 16, that is, the voltage drop, is at least about 19V, the first
The voltage of the control output signal applied to the relay 14 drops to about 5V at (24-19). Therefore, when the first relay 14 is on, the output voltage V 0 will be approximately 5V, and when the first relay 14 is off, it will be 0V.
In this case, both are the operating voltage of the second relay 15.
Since the voltage is lower than 12V, the second relay 15 will not be affected and will not be controlled by the monitored control device regardless of whether the first relay 14 is on or off.

１１には影響を与えることはなくなる。 In this way, when the switch 13 is switched to the lower side, when the value of the output voltage V 0 is measured using a tester etc., when it is 5V, the control output signal is turned on.
When the voltage is 0V, the control output signal is off, so it is possible to check whether the control output signal is on or off.Moreover, when checking, the relay of the monitored control device 11 is not operated, and the monitored control device 11 is turned off. will no longer be affected.

例えば、半導体素子で構成してもよい。 In addition, if the voltage setting circuit outputs a voltage that is lower than the operating voltage of the second relay,
There are no particular limitations on the circuit configuration. If the switching switch switches the terminals of the voltage setting circuit mentioned above,
The operation mode does not particularly matter. The first relay may also be simply opened and closed, and the operation mode is not particularly limited.
Further, the second relay may be of a contact type or a non-contact type as long as it has a predetermined operating voltage.
For example, it may be composed of a semiconductor element.
