Programmable Controller

The programmable controller has a programmable digital arithmetic logic circuit and can communicate with external devices through the I/O interface. Programmable controllers can be customized according to professional needs to meet the needs of various industrial environments and control various types of mechanical equipment.

FPGA

Introduction:
The FPGA (Field Programmable Gate Array) is a collection of several digital circuits, with a large number of digital I/O pins, which can realize complex logic operations. FPGA has the characteristics of fast processing speed, parallel processing, and not easy to collapse, but its I/O interface can only accept digital logic signals, and its driving ability is poor. FPGA has strong customization and versatility, but it is hard to design its executive program.

Working principle:
1. Design the executable program according to the needs.
2. The executable file is generated by the development tool and downloaded to the FPGA through the simulator.
3. After power on, FPGA will automatically load the executable program.

The role of solid state relays:
1. Control the working status of actuators.

MCU

Introduction:
The MCU (Microcontroller Unit, or Single Chip Microcomputer) is a kind of integrated circuit chip, which integrates CPU, RAM, ROM, I/O interface, Timer, etc., and can be regarded as a fully functional microcomputer system. There are lots of MCU in the market, like STM32 MCU, 51 MCU, ATMEGE 328P MUC and so on. The MCU cannot be used alone, and it need peripheral circuits to execute the program.

Working principle:
1. Write the executable program directly through the computer.
2. Burn the executable file to the MCU through the burning program.
3. After power on, the MCU will automatically load the executable program.

The role of solid state relays:
1. Control the working status of actuators.

PLC

Introduction:
The PLC (Programmable Logic Controller) is mainly used to control various types of industrial equipment, and is composed of industrial-grade MCU and general-purpose peripheral circuits. Compared with the MCU, PLC has very strong stability and reliability: Its internal codes are strictly executed in order, and its peripheral circuits and packaging have strong anti-interference ability and high industrial protection level (IP67). The drive capability of PLC is very strong, and its I/O interface can be directly connected to industrial devices.

Working principle:
1. Write the executable program directly through the computer.
2. Load the executable file into the firmware of the PLC through the specific driver.
3. The executable file will be executed after the internal analysis of the PLC firmware.

The role of solid state relays:
1. Control the working status of actuators.

Recommended Solid State Relay

Printer

The printer can print the files processed by the computer to the material medium after a series of operations. For traditional printers, the content of the file will be printed on two-dimensional flat paper. For 3D printers, the file content will be printed on plastic materials, such liquid photosensitive resin, plastic, gypsum powder, etc.

Multifunction Printer

Introduction:
The multifunction printer integrates functions such as printer, scanner, and copier. Some multifunction printers also have fax and telephone functions.

Working principle:
1. Open the file through the computer and select the print command.
2. The printer will automatically print the content of the file onto paper.

The role of solid state relays:
1. Control the working status of the actuator.

3D Printer

Introduction:
The 3D printer (three-dimensional printer) is a device that produce a three-dimensional model through layer-by-layer stacking.

Working principle:
1. Make a 3D digital model through design software and import it to the 3D printer.
2. Inject the raw materials into the printer to print the 3D model.

The role of solid state relays:
1. Control the working status of the actuator.
