Problems solved by technology

This method also needs to use screws to lock the pins one by one, which is very time-consuming.
Moreover, the entire device is only stressed through the pins, and it is easy to cause the pins to shift and the device to fall off when there is an external force pulling the wire

Embodiment 1

[0028] refer to figure 1 , is a schematic structural diagram of Embodiment 1;

[0029] The input module for industrial PLC in Embodiment 1 includes a PCB board 1 , a PLC connector 2 , an input signal socket 3 , a control signal socket 4 , and a 220V power input socket 5 .

[0030] figure 1 Among them, the bold line shows the PCB board 1, the PLC connector 2 is welded on the back of the PCB board 1, and the input signal socket 3, the control signal socket 4, and the power input socket 5 are welded side by side on the PCB1 board On the back and on the side of the PLC connector 2.

[0031] The input module of this embodiment is used as a conversion device for input signals. After the signals of external equipment are input through different sockets 3, 4, and 5, they are then transmitted to the PLC through the PLC connector. Specifically:

[0032] The input signal seat in this embodiment is a 90-degree bull-horn seat of 2x17Pin, on which is the status information input to the C...

Embodiment 2

[0049] Based on the same inventive concept, this embodiment discloses an output module for industrial PLC, refer to Figure 5 , is the structural representation of the second embodiment. The output module of this embodiment includes a PCB board 1 , a PLC connector 2 , and an output signal socket 3 . The PLC connector 2 is welded on the back of the PCB 1, and the output signal seat 3 is welded on the back of the PCB 1 and is located on the side of the PLC connector 2. The structure of the PLC connector 2 of this embodiment refers to the embodiment one.

[0050] One of the differences between Embodiment 2 and Embodiment 1 is that the seat on the PCB only has a 90-degree horn seat 3 of 2x20Pin. The horn seat and the cable are connected to the external motor. The signals transmitted by the horn seat include: Y0, Y1, Y2, ... Y27 and other motor control signals and COM1, COM2, ... COM5 and other common terminal signals.

[0051] In addition, the fool-proof structure set on the PC...

Abstract

The invention discloses an input module and output module for an industrial PLC (Programmable Logic Controller). The input module comprises a PCB, a PLC connector, an input signal seat, a power sourceinput seat and a control signal seat; the output module comprises a PCB, a PLC connector and an output signal seat; the PLC connector includes an upper end structure and a lower end structure; the lower end structure has two fixing grooves; the upper end structure is provided with two rows of pin headers which are corresponding to the two fixing grooves and are soldered to the PCB; and a row of metal clamping sheets which are arranged at intervals is located in each fixing groove. According to the input module and output module of the invention, the input module and output module are directlymounted on the PLC through the connectors, which enables simplicity and convenience and can save labor cost; the connection of the connectors is safe and reliable, short circuits and poor connectionscan be avoided, and a large quantity of wires and wiring space can be saved; the input module and output module are easy to expand and can be applied to actual production on a large scale; and the input module and output module are convenient and firm in wiring, low in cost and are easy to replace.

Description

technical field [0001] The invention relates to the field of industrial automation, in particular to an input module and an output module used in an industrial PLC. Background technique [0002] Programmable logic controller, referred to as PLC (Programmable logic controller), is an electronic device specially designed for digital operation in industrial environments. It uses a memory that can be programmed to store instructions for performing operations such as logic operations, sequential operations, timing, counting, and arithmetic operations, and can control various types of devices through digital or analog inputs and outputs. machinery or production process. PLC and its related peripheral equipment are easy to form a whole with the industrial control system, so they are widely used in various fields of industrial control. [0003] The connection between PLC and field I / O equipment or other external equipment is accomplished through input and output interfaces. The P...
