文档介绍：摘要
目前PC已广泛应用于冶金、化工、轻工、机械、电力、建筑、交通、运输等各行各业。
随着机电一体化的发展,对不系统的可靠性要求愈来愈高。可编程控制器有控制可靠,体积小,功能强,速度快,组态灵活和可扩展的特点而得到广泛的应用。可编程控制器是20世纪60年代末在继电器控制系统的基础上开发出来的。最初叫做可编程逻辑控制器,(programmable logic controller)即PLC。
在我国,PC的应用最近几年发展很快。首当先应用一些大中型现代化工厂的引进工程上,如上海宝山钢铁总厂一、二期工程中就使用了PC达857台。武汉钢铁厂和首都钢铁厂等大型钢铁企业也都使用了许多PC。
在老企业旧设备的技术改造上,PC的应用比较广泛,而且已取得了可喜的经济效益。
PC是专为工业控制设计的控制装置,能适应工业现场的恶劣环境,例如:
电源电压:AC220V±15%。
抗振强度:,3mm双振幅(X、Y、Z三个方向各30min)。
工作温度:0~55℃,有的甚至可以是-10~55℃。
存放温度:-20~60℃。
湿度:35~90%RH无凝结。

Abstract
At present, PC has been widely used in metallurgy, chemical industry, light industry, machinery, electric power, building, transportation, transportation and other industries.
With the development of the electromechanical integration, the reliability of the increasingly high demand not system. The programmable controller has reliable control, small volume, powerful function, fast speed, configuration flexible and scalable and has been widely applied. The programmable controller is in the late een sixties relay control system based on the developed. Originally called a programmable logic controller, (programmable logic controller ) PLC.
In our country, the application of PC in recent years the rapid development. The first application for a number of large and medium-sized modern factory introduction project, such as Shanghai Baoshan iron and steel plant one or two phase of the project in the use of a PC of 857. Wuhan Iron and steel plant of large iron and steel enterprises and the capital iron and steel plant are also used for many PC.
In the technical renovation of old enterprises of old equipment, PC is used widely, and have made remarkable economic benefit.
PC is designed for control device for industrial control design, can adapt to the harsh environment of industrial site, for example:
The power supply voltage: AC220V ± 15%.
Vibration strength: , 3mm double amplitude ( X, Y, Z three directions in the 30min ).
Working temperature: 0
