The present invention relates to a port conversion apparatus for PLC. More particularly, at the time of replacing PLC with another type, a first input and output terminal, which has been used in an existing first type PLC module, does not need to be separated from wires connected thereto and can be used in a second type PLC module and therefore, the present invention enables easy PLC replacement and prevention of wiring errors arising in the process of separating and recombining wires and further enhances convenience of PLC replacement work through a card accommodation case accommodating a port conversion card and maintains a simple outer appearance. A port conversion apparatus for PLC according to the present invention connects the first type input and output terminal coupled to the first type PLC module having the first type input and output port to the second type PLC module having the second type input and output port, the invention comprising: a port conversion card including a body, an input port provided at one side of the body in a shape corresponding to the first type input and output port so that the first input and output terminal can be coupled, an output port provided on the other side of the body, and conversion wires capable of electrically connecting a plurality of contact points provided on the input port and the output port; and a connection cable with one end portion provided with a connector to be coupled to the output port of the port conversion card and with the other end portion provided with a second type input and output terminal which is electrically connected to the connector and which is able to be coupled to the second type input and output port. |
