2a, the detection signal output from the rotation speed detection sensor 30 is converted to the I / F circuit 48.
A data transmission circuit 54a for outputting to the lead wire 47 through the line a, and an I / F circuit 56a for connecting the data transmission circuit 54a to the rotation speed detection sensor 30 are provided. The I / F circuit 48a is connected to the I / F circuit 16 of the controller 12 via a lead 47.

In the control device 10 configured as described above, the controller 12 outputs a drive signal to an actuator, for example, a motor 20, and reads the number of rotations of the motor 20 from the number of rotation detection sensor 30. Will be described below.

First, a connector number of a connector, for example, a hexadecimal number (hereinafter, H) is set in a setting device 40a of the connector 18a.
) Is set to “10H”. Similarly, setting devices 40b, 40c, 40 of connectors 18b, 18c, 18d

Therefore, the controller 12 controls the I / F circuit 1
4 outputs a 2-byte signal, for example, a signal “10H, FFH” to the lead line 37.

In this case, the first byte indicates connector designation information, and the second byte indicates a drive signal for the actuator.

Of the signals "10H, FFH", the first byte signal "10H" is the I / O signal of the connectors 18a to 18d.
The determination circuits 42a-42 via the F circuits 38a-38d, respectively.

As described above, according to this embodiment,
The connectors 18a to 18d determine whether the connector designation information output from the controller 12 matches the connector number information of the connectors set in the setting devices 40a to 40d, and only the matched connectors are output from the controller 12. Therefore, a single port of the controller 12 can be connected to each of the connectors 18a to 18d by the lead wire 37.

Further, the connectors 28a to 28d determine whether or not the connector designation information output from the controller 12 matches the connector number information of the connectors set in the setting devices 50a to 50d. Since the detection signal can be relayed and transmitted to the controller 12, a single port of the controller 12 and each of the connectors 28a to 28d can be connected by the lead wire 47.

According to the connector of the present invention, each actuator can be connected to a single output port of the controller, and each detecting means can be connected to a single input port of the controller. Thus, the number of ports of the controller can be reduced, and the number of connection lines connected to the controller can be reduced.

Accordingly, the size of the entire apparatus can be reduced, and the manufacturing cost of the apparatus can be reduced.

Further, by reducing the number of connection lines connected to the controller, it is possible to easily find a defective portion at the time of maintenance and to reduce the time required for maintenance.
