PURPOSE:To lessen manhour and prevent erroneous wiring by reducing wiring within a control device. CONSTITUTION:A terminal panel 7 has a terminal 7a for connection to an A-system output card 2 and a B-system output card 5, and an external terminal 7d for connection to an external plant. Also, the panel 7 is fitted with a relay 8 to output a control signal to a valve or the like of the external plant, upon being excited with a signal from the card 2 or 5. Furthermore, the terminal 7a and the relay 8 are connected to each other with a cable 7b, and the relay 8 is connected to the external terminal 7d with a cable 7c for providing a unit configuration, thereby enabling wiring to be reduced within a control device. |
