In the block configuration diagram of FIG. 2, the measurement input signal data regarding the temperature and the like from the sensor 7 is supplied to the terminal 51 of the terminal portion 5, and the input means 8 performs input processing such as amplification, A / D conversion, and necessary linearization. Done. The processing means 9 such as a microcomputer having the memory 10 compares the measured data of the input means 8 with the set values set by the display means 2, the setting means 3 and the like to perform control operation processing such as PID control operation and output. An operation output signal is generated externally from the terminal 53 of the terminal portion 5 via the means 11.

In addition, from the terminal 54 of the terminal portion 5 to the AC power source 1
2 is taken in, and a DC voltage is supplied by the power supply 13, and the DC power for operation is supplied to each means of the measuring circuit. Further, the operation output signal controls ON / OFF of the AC power supply 12 supplied to the control target 15 via the operation end 14 such as SCR or SSR. Further, the processing means 9 is the interface 1
6, the terminal 52 of the terminal portion 5 is connected to the external operation indicator 17 such as a personal computer shown in FIG.
Thus, the setting value of the controller 1 can be set and the measurement value can be collected.

That is, the controller 1 of the present invention is in the form of a card, and can be installed at any desired location according to the controlled object 15, and can be adjusted and controlled, and stored in the memory 10 of the processing means 9. The collected measurement data can also be collected by the external operation display unit 17, and a large number of the controllers 1 can be provided for each control target 15 and can be centrally managed by the operation display unit 17.

Further, as shown in FIG. 3, a network between the controller 1 and the sensor 7, or between the controller 1 and the operating end 14, or between the controller 1 and the operation display 17 is connected. Such a bus may be used for data transmission by connection, or wireless or infrared contactless communication may be used instead of the bus. In this case, communication modules may be provided in the controller 1, the sensor 7, the operation end 14, the operation display 17 and the like so that data can be exchanged by bus or in a non-contact manner.

As described above, by remotely setting the set value of the controller 1, inputting the input signal, or outputting the operation signal, the sensor, the operating end, and the controller can be installed anywhere. Yes, it is more flexible and space saving is possible.

That is, the sensor 7 can be built in the base 1A or installed remotely to input an input signal,
It can be selected and used as needed. When it is remote, the sensor 7 can be installed at a required location, and the measured value can be transmitted to the controller 1 wirelessly or the like to accurately control the required location.

The operating end 14 may be incorporated in the base 1A or may be installed remotely, and can be selected and used as required.

The set value can be set by the setting means 3 provided on the base 1A or the display operation device 17 installed remotely, and can be selected and used as required.

Further, by storing the measurement data in the memory 10 so that the data can be read, the data can be collected and both measurement and control can be performed.
