When starting equipment at a controlled facility using Make PC 3 active. Then, when the activation command unit Q 3 of the external device sends a activation signal via the communication line L 2 , the activation photocoupler PC 1 becomes active, and P 1 - PC 1
A circuit of -D 1 -PC 3 -D 3 -L 1 -A-ZD-R 4 -(base of transistor Tr) -(emitter of transistor Tr) -N 1 is constructed. At this time, the zero voltage power supply line G 1 based on the negative voltage power supply line N 1
When a constant voltage diode ZD with a Zener voltage VZ slightly higher than the voltage of the transistor Tr is used, the voltage VA of the terminal A seen from the emitter of the transistor Tr becomes higher than the Zener voltage VZ
A current flows through the base of. Since the transistor Tr is a grounded emitter circuit, the base current is amplified and the operation auxiliary relay CX connected to the collector side of the transistor Tr is energized, and the a contact CXa of the relay CX closes, R-CXa

おいて動作信号は検出されない。 Next, a case will be described in which the external device O is used to stop equipment on the controlled site side. When the device is in the starting state, as described above, the a contact 42a of the main circuit electromagnetic contactor 42 closes, which causes the transistor Tr to operate, and the operation auxiliary relay CX to self-hold. Device selection command unit of external device O
A signal for selecting the device to be stopped is sent from Q5 via the communication line L4 , and the signal activates the device selection photocoupler PC3 . Then, when a stop signal is issued from the stop command unit Q 4 and the stop photo coupler PC 2 is activated, P 1 −R 2 −
A circuit of 42a-A- L1 - D4 - PC3 - D2 - PC2 - G1 is constructed and current flows. At this time, the magnitude of the current is limited by the resistor R2 so that the photocouplers PC2 and PC3 are not destroyed by the current. In this case, the voltage VA at terminal A is almost equal to the zero voltage power supply line.
Since the potential is the same as that of G1 , the voltage VA at terminal A with respect to the emitter of transistor Tr becomes lower than the zener voltage VZ.Therefore, no current flows to the base of transistor Tr, and the operation of transistor Tr is reduced. stops, operation auxiliary relay CX is deenergized, and operation auxiliary relay CX is deenergized.
The a-contact CXa of CX is opened, the main circuit magnetic contactor 42 is deenergized, and the equipment is stopped, and the a-contact 42a of the main circuit magnetic contactor 42 is opened, and the relay CX is connected to the main circuit magnetic contactor 42. 42's self-hold is released. In this case, the anode and cathode of photocouplers PC 4 and PC 5 are at the same potential, so no current flows through them, so photocoupler PC 4 and PC 5 do not operate, and the light emitting diode LED turns off. It is possible to confirm that the equipment at the controlled facility has stopped by checking the
Since no operation signal is sent to the Q1 , no operation signal is detected in the operation detection section Q1.

い。 When using the toggle switch SW for start/stop to stop equipment at the controlled station, use the toggle switch SW.
Put the SW into the stop side contact. Then, P 1 −R 2 −
A circuit 42a-A- L1 -- G1 is formed and current flows through this circuit. In this case, the voltage at terminal A
Since VA has almost the same potential as the zero-voltage power supply line G1 , as mentioned above, the operation of the transistor Tr, auxiliary relay CX, and main circuit electromagnetic contactor 42 stops, and the specified equipment in the controlled station stops. Stop. and,
The self-holding of the auxiliary relay CX is released, the operation of the operation detection photocoupler PC 4 is stopped, and the light-emitting diode LED is turned off, making it possible to confirm the stopped state of the device. Further, no operation signal is detected in the operation detection section Q1 of the external device.

は押釦スイツチPBSを押すことによつて行なう。 Next, a case will be described in which a failure occurs in equipment at a controlled facility due to overcurrent. When the equipment at the controlled station is in the activated state, as described above, the a contact 42a of the main circuit electromagnetic contactor 42 is closed, the transistor Tr is operated, and the auxiliary relay CX is self-maintained. In this case, when an overcurrent flows through the device, the overcurrent relay mechanical contact 51a is activated, and at the same time, the a contact 42a of the electromagnetic contactor 42 is opened.
Then, the voltage VA at terminal A becomes lower than the potential of the zero-voltage power supply line G and lower than the Zener voltage VZ, so the operation of the transistor Tr stops, and accordingly, the operation of the auxiliary relay CX also stops.
Contact CXa is opened, the operation of the electromagnetic contactor 42 is stopped, and the equipment is stopped. Then, a forward voltage is applied to the fault detection photocoupler PC 5 , and G 1 −R 1 −
The circuit PC 5 -L 1 -A-51a-R 3 -N 1 is configured, current flows through this circuit, the fault detection photocoupler PC 5 operates, and this signal (fault signal) and the flicker generation integrated circuit IC The light emitting diode LED blinks due to the AND with the Fritzker signal created in step 3 , making it possible to confirm that the device is in a fault state due to overcurrent, and the fault signal is transmitted externally via the connection line L 6 . The signal is sent to the device O, and a failure signal is detected in the failure detection unit Q2 . Also,
Using the rising edge of the fault signal, a trigger pulse for the photothyristor PS is created in the pulse generation integrated circuit IC 4 , and the alarm BZ sounds through the photothyristor PS. Stopping the alarm BZ's alarm is done by pressing the push button switch PBS.

る。 That is, unlike conventional devices, semiconductors are used instead of communication relays between the control center and the controlled station to perform control, detection, and display, allowing for centralized monitoring by connecting to an external device such as a computer. In this case, compared to conventional devices, the mounting density on the board and noise resistance can be improved, and power consumption can be reduced as much as possible.
Furthermore, when using conventional communication relays, there are problems with reliability and durability due to poor operation of the relay contacts and contact life, and the large current flowing through the control and detection communication lines makes it difficult to extend the control distance. It is possible to solve the problems such as not being able to connect to an external device for centralized monitoring made of semiconductors and requiring a large amount of interface.
