Technical Field
[0001] The utility model relates to the technical field of automation equipment, in particular to an energy-saving PLC programmable controller. Background Art
[0002] PLC has developed into a series of products of various sizes, large, medium and small. It can be used in industrial control occasions of various sizes. In addition to the logic processing function, most modern PLCs have perfect data computing capabilities and can be used in various digital control fields. With the enhancement of PLC communication capabilities and the development of human-machine interface technology, it has become very easy to use PLC to form various control systems.
[0003] PLC uses storage logic instead of wiring logic, which greatly reduces the external wiring of the control equipment, greatly shortens the design and construction cycle of the control system, and makes maintenance easier. More importantly, it makes it possible to change the production process of the same equipment by changing the program. This is very suitable for multi-variety and small-batch production sites.
[0004] However, the existing energy-saving PLC programmable controller has the following problems during use: because conventional PLC products require external expansion modules to connect with the equipment, the connection is inconvenient and energy-consuming. Therefore, it is necessary to design corresponding technical solutions to solve the existing technical problems. Utility Model Content
[0005] The purpose of the utility model is to provide an energy-saving PLC programmable controller, which solves the technical problems of inconvenient connection and high energy consumption caused by the need for external expansion modules of conventional PLC products to connect with devices, and meets actual use needs.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: it includes an outer shell, a circuit board body is arranged inside the outer shell, interface one is arranged on both sides of the circuit board body and between the outer shell, a control switch and interface two are respectively arranged on the top of the circuit board body and between the outer shell, interface three is arranged on the side of the circuit board body, and a processor module is arranged on the top of the circuit board body.
[0007] As a preferred embodiment of the utility model, the outer shell is composed of an upper shell and a lower shell, the upper shell is provided with a through hole 1 used to cooperate with the interface 1 and the control switch, the side of the upper shell is provided with a through hole 2 used to cooperate with the interface 3, and a plurality of fastening bolts are provided on the bottom of the lower shell and between the upper shell, and the fastening bolts are embedded in the lower shell.
[0008] As a preferred embodiment of the utility model, a plurality of indicator lights are evenly arranged on the circuit board body, and a translucent structure is provided at a position on the upper shell corresponding to the indicator lights, and the indicator lights correspond to indications of the interface one, the control switch and the interface two.
[0009] As a preferred implementation manner of the utility model, the second interface is a serial port: COM1 port, and the control switch controls STOP and RUN.
[0010] As a preferred implementation manner of the present utility model, the interfaces 1 at different positions are respectively a signal input end and a signal output end, and the interface 1 being the signal output end is an RS-485 port.
[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0012] By optimizing the internal circuit of the circuit board and adding a set of communication interfaces (RS-485 port), the expansion module on the conventional PLC controller can be cancelled. Only 4AD (interface one, 4 groups of analog inputs) and 2DA (interface one, 2 groups of analog outputs) are needed to complete the signal transmission, thereby saving space inside the controller, reducing energy consumption, and effectively improving the response speed, thus solving the problem of inconvenient connection and high energy consumption.
