摘要
在现代工程设计中,传统使用的PLC控制已经不适合基础系统。介绍了一种基于单片机的可编程控制延时开关和其可控制的负载,该开关可以在电路中使用光耦隔离,以避免外部的干扰。同时,开关还具有成本低、性能稳定等优点,被广泛应用。
In modem engineering design, PLC control traditionally used is not suitable for the base system. Introduced a microcomroller based programmable control delay switch, and it can control the load, the switch can use the optical isolation circuit to avoid external interference. Meanwhile, the switch also has a low cost, stable performance, etc., are widely used.
