Description

I/O signal switching device of PLC controller

Technical Field

The utility model belongs to the technical field of the PLC controller, especially, relate to a IO signal switching device of PLC controller.

Background

In the field of industrial automation, various Programmable Logic Controllers (PLCs) are widely used due to the need for automatic control of the production process. The PLC is generally directly installed in a control site, and is connected to sensors, controllers, and communication devices in the control site through various cables. The cables are directly connected to corresponding functional modules of the PLC according to functional division, so that the PLC is in one-to-one correspondence with various external devices in connection form.

At present, when a PLC control system is debugged and tested, connecting wires on a PLC are required to be unscrewed one by one through a screwdriver, and then the connecting wires are connected to a testing machine one by one for debugging. Because PLC's wiring is more for a large amount of wiring (especially need carry out above-mentioned work to a large amount of PLC when the engineering application, work load can be bigger) need be dismantled and reinstalled to the debugging process, makes the operation process very troublesome, has consumed a large amount of manpower and materials, and work efficiency is low.

SUMMERY OF THE UTILITY MODEL

In order to overcome the not enough of prior art method, the utility model aims to provide a IO signal switching device of PLC controller for PLC control system debugging test process need not to dismantle and install a large amount of wiring again, makes debugging operation process swiftly convenient, great improvement work efficiency, realize the harmless of PLC wiring and draw forth.

In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a IO signal switching device of PLC controller, includes base plate, PLC connector card and connection socket be provided with PLC connector card and connection socket on the base plate, the wiring end of PLC connector card and connection socket's wiring end are through arranging the circuit that sets up one by one on the base plate and are linked together, the PLC connector card is pegged graft in PLC binding post's slot, connection socket connects and draws forth the wire.

Further, the PLC connecting card is a strip-shaped connecting card, and a plurality of conductive contact pieces are arranged on the strip-shaped connecting card and serve as wiring ends of the PLC connecting card.

Furthermore, the connection socket adopts a plurality of groups of sub-sockets. Be convenient for distinguish and connect and participate in, improve the grafting convenience.

Further, the connection socket adopts a PIN socket. Is convenient for plugging.

Further, a reinforcing plate is disposed below the base plate. The device is reinforced in use, and meanwhile, partial insulation protection effect can be carried out on the bottom plate, so that the situation that the exposed cable possibly existing in the field directly touches the welding point of the bottom plate is avoided.

Further, the reinforcing plate and the base plate are connected through a support rod.

The beneficial effects of the technical scheme are as follows:

the utility model discloses lift PLC's binding post off, directly insert on this keysets's plug-in card, with the wiring disect insertion on the test machine to the patch panel's socket for on can avoiding the dismantlement and the installation to the every wiring of PLC, make PLC control system debugging test process need not to dismantle and install a large amount of wiring again, make debugging operation process swiftly convenient, great improvement work efficiency. The PLC controller is particularly suitable for a PLC controller which can disassemble a lower wiring terminal, in particular to Schneider PLC.

The utility model discloses do not change the signal connection of original PLC functional module, after accomplishing measurement and debugging, original operating condition is resumeed to that can be convenient, realizes that the harmless of PLC wiring draws forth.
