relay-operated controller

Note that an alarm relay in the controller is not sufficient protection for all eventualities.

注意;控制器内的报警继电器不是在任何情况下都能提供有效保护.

This paper introduces a PLC controller, which takes the place of relay-operated controller, to control the folding cement package machine

为了提高传统的水泥袋折边机的工作效率，采用PLC控制器代替电磁时间继电器进行逻辑顺序控制，使机器的折边效率大大提高

Based on the standard relay output module and ATX power supply, the auto-switching test platform and the testing control software of host controller and digital signal processing sub-system are designed.
