Programmable controller is the computer technology and automation technology suitable for industrial environments combining a new universal automatic control device and developed as a conventional relay replacement product emerged. With the rapid development of microelectronics and computer technology, PLC more of a function of the computer, not only to implement logic control, but also with the data processing, communications, networking and other functions. Because it can be changed through software control process, and has a small, assembled, easy maintenance, simple programming, high reliability, strong anti-interference ability and other characteristics, has been widely used in industrial control, greatly promoted the mechatronics process. Distributed Control System (DCS Distributed Control System) is a high performance, high quality, low cost, flexible configuration of distributed control system products, can pose a variety of independent control systems, distributed control system DCS, supervisory control and data acquisition system (SCADA), industrial product promotion, to meet the needs of various industrial process control and information management. The modular system design, rational configuration of hardware and software features and easy to expand capacity, to a wide variety of large, medium and small-scale power station renovation decentralized control, power plant automation systems and steel, petrochemicals, paper, cement, etc. industrial process control. IPC motherboard typical environment, as; Operating temperature: -40 degrees range up to 85 degrees Humidity: range up to 0 to 95% non-condensing environment Dust: metal dust, general dust electromagnetic radiation: strong electromagnetic interference environment, Zhengzhou High-tech Zone industrial products, radiation control for a long time to work itself: under permanent power over the life of these environments generally are not competent commercial board. Main applications Main applications: industrial equipment, industrial products supplier, GPS navigation, sewage-line monitoring, air-line monitoring, instrumentation, professional equipment control, military, industrial products companies, government agencies, telecommunications, banking, electricity, car LCD, monitors, video door phone, portable DVD, LCD TV, and environmental protection equipment and other industrial products prices, the study Connaught Electrical and Mechanical (certified), Zhengzhou High-tech Zone Industrial products offered by conventional Connaught Mechanical and Electrical Equipment Co., Ltd., Henan.
