HONEYWELL 05701-A-0326可编程逻辑控制器是小型工业计算机。他们的设计在单个设备中使用模块化组件来自动化定制的控制过程。它们不同于大多数其他计算设备，因为它们适用于工厂设置的恶劣条件，如灰尘、潮湿和极 端温度。

工业自动化早在PLC之前就开始了。在他们发明之前的20世纪早期，控制机器的唯 一方法是通过使用复杂的机电继电器电路。每个电机都需要单独开启/关闭。这导致工厂需要装满功率继电器的巨大机柜。

HONEYWELL 05701-A-0326随着工业自动化的不断发展，当时的现代工厂需要几十个带开/关开关的电机来控制一台机器，所有这些继电器都必须以非常特殊的方式硬连线。PLC是作为一种解决方案开发的，它具有一个固体控制，作为硬连线继电器系统的电子替代品。

HONEYWELL 05701-A-0326 Programmable Logic controllers are small industrial computers. Their design uses modular components in a single device to automate customized control processes. They are different from most other computing devices because they are suitable for harsh conditions in factory Settings, such as dust, humidity, and extreme temperatures.

Industrial automation began long before PLCS. Before their invention in the early 20th century, the only way to control a machine was through the use of complex electromechanical relay circuits. Each motor needs to be turned on/off separately. This led to the need for huge cabinets filled with power relays.

HONEYWELL 05701-A-0326 As industrial automation continued to evolve, modern factories at the time required dozens of motors with on/off switches to control a single machine, all of which had to be hard-wired in very special ways. The PLC was developed as a solution with a solid state control as an electronic alternative to hard-wired relay systems.
