工业 0V 到 + 10V 数字电位器

资料介绍
摘要: 交流和直流电机在现代工业系统中的通常都是通过可编程逻辑控制器 (可编程控制器) 凡工业机械电位器控制电机转速控制。这些电位器的刮水器可以成为戴在一段时间。这篇文章讨论了一个简单的电路,使用几个固态表面贴装设备。它使用数字电位器来实现同样的性能、 消除了出来,穿的刮水器接触问题和长远节省资金。

Abstract: AC and DC motors in modern industrial systems are often controlled via programmable logic
controllers (PLCs) where an industrial mechanical potentiometer controls the motor speed. The wiper of these
potentiometers can become worn over a period of time. This article discusses a simple circuit using few solid-
state surface mount devices. It uses a digital potentiometer to achieve the same performance, eliminates
problems with wiper contacts wearing out, and saves money in the long run.
