摘要
文章介绍了一种数控装置的双门槛频率控制电路。当二个传感器的输出均达到门槛频率时,通过电路接通继电器使数控装置运行,只要有一个传感器的输出低于其门槛频率,则继电器就不吸合,数控装置停止工作,从而达到控制数控装置运行的目的。
The article introduces a kind of dual threshold frequency control circuit for digital control device. When the outputs of the two sensors both reach the threshold frequency, via the circuit to connect through the relay to make the digital control device in operation, povided the output of one sensor is less than the threshold frequency, the relay then won't work, the digital control device stops work, therefore to achieve the aim of controlling the operation of the digital control device.
