Description
The Programmable Logic Controller was first introduced in the United States in the late 1960s, when it was called the Programmable Logic Controller (PLC), which was used to replace relays. To perform logical judgment, timing, counting and other sequential control functions. The concept of PLC was proposed by General Motors. The basic design idea of PLC is to combine the advantages of computer function perfect, flexible, universal and relay control system simple and easy to understand, easy to operate, cheap and so on, the controller hardware is standard and universal. According to the actual application object, the control content is compiled into software and written into the user program memory of the controller, so that the connection between the controller and the controlled object is convenient. PLC features and functions (1) The main characteristics of plc. The characteristics of plc are: reliable work, fast running speed, building block structure, flexible combination, good compatibility, simple programming and generation, rich, strong network function. (2) The main functions of plc. plc system can well complete the industrial real-time sequence control, condition control, counting control, step control and other functions; It can complete analog/digital (a/d), digital/analog (d/a) conversion, data processing, communication networking, real-time monitoring and other functions. Years of practice shows that plc, reliable, is designed for the factory, with reinforced components according to the requirements of the working environment, real-time scanning practice and fault diagnosis function, easy troubleshooting, won the preference of users. What makes a plc so reliable is a real-time core or operating system of executable relay logic, sequential function diagrams, function blocks, structured text, command catalogs, or a combination thereof. In case of failure, the built-in device can maintain mechanical damage and maintain an orderly and predictable sequence. 2.4 The development trend of plc: there are extremely fast logical operations and logic control, sequence control capabilities, reliability in discrete control, convenient and easy to learn programming methods, so that it has an undisputed position in the field of industrial automation based on discrete.

ABB power module features and applications
ABB power module uses advanced integrated circuit technology to integrate power devices and logic control circuits in a highly integrated, fully sealed integrated block with power function. The power module has the advantages of convenient use and reliable performance, which represents the development direction of power supply technology. Because the switching power supply has the advantages of high efficiency and small size, it is suitable for integration. Because of its low efficiency, generally about 50%, it is difficult to achieve high-power (more than 100W) integration. The power module introduced by Jimi technology refers to the switching power module, focusing on the DC/DC converter. Today's switching power modules can reach hundreds of watts or even kilowatts.
Power module products mainly include DC/DC converter module, power factor correction module, AC input module, etc. Their main characteristics are:
◆ ABB power module working frequency is high, generally 300KHz~1MHz.
◆ ABB power module size is small, ultra-thin, thickness is generally less than 20mm, light weight, generally less than 200g.
◆ ABB power module power density is large, generally 5~10W/ cubic centimeter.
◆ ABB power module is easy to use, less external components, can be expanded in parallel, and can also realize logic control and remote control.
◆ ABB power module is suitable for a wide range of power grid voltage changes. When the general AC voltage fluctuates between 150V and 280V, the output has a voltage regulator function.
◆ ABB power module temperature adaptation range is wide, can be from -55 degrees Celsius ~+100 degrees Celsius, the general high temperature substrate temperature is +85 degrees Celsius, low temperature 0 degrees, -20 degrees, -40 degrees, -55 degrees and other levels.
◆ ABB power module fully sealed package, with three anti-function, waterproof, dustproof, anti-impact.
◆ ABB power modules generally use zero voltage switch or zero current switch technology, good electromagnetic compatibility.
◆ ABB power module structure is highly standardized and easy to install.
