1336-L4 可编程逻辑控制器 可承受更宽的温度变化范围

1336-L4 可编程逻辑控制器（Programmable Logic Controller，简称PLC）是一种专为工业环境应用而设计的数字运算操作电子系统。它采用一种可编程的存储器，在其内部存储执行逻辑运算、顺序控制、定时、计数和算术运算等操作的指令，通过数字式或模拟式的输入输出来控制各种类型的机械设备或生产过程。PLC是计算机技术与自动化控制技术相结合而开发的一种适用工业环境的新型通用自动控制装置，是作为传统继电器的替换产品而出现的。PLC的出现大大提高了工业生产的效率和可靠性，是现代工业自动化控制的重要组成部分。此外，PLC还可根据需要扩展模拟量控制功能（国外也称PAC），配置有多个输入和输出装置，可承受更宽的温度变化范围，更苛刻的电气噪声、振动和冲击等。这使得PLC能够在各种恶劣的工业环境下稳定运行，为工业自动化提供了强大的支持。

1336-L4 Programmable Logic Controller (PLC) is a digital operation electronic system designed specifically for industrial environment applications. It adopts a programmable memory that stores instructions for performing logical operations, sequential control, timing, counting, and arithmetic operations inside, and controls various types of mechanical equipment or production processes through digital or analog input and output. PLC is a new type of universal automatic control device developed by combining computer technology and automation control technology, suitable for industrial environments. It has emerged as a replacement product for traditional relays. The emergence of PLC has greatly improved the efficiency and reliability of industrial production, and is an important component of modern industrial automation control. In addition, PLC can also expand analog control functions (also known as PAC abroad) as needed, equipped with multiple input and output devices, which can withstand a wider range of temperature changes, more stringent electrical noise, vibration, and impact. This enables PLC to operate stably in various harsh industrial environments, providing strong support for industrial automation.
