In the temperature and humidity control system of the clean operating room, the temperature and humidity control is a complex process with nonlinearity, large lag, and time variation. This article introduces the S7-200 PLC as the main controller to realize PID control of temperature and humidity under different working conditions. The operating results show that the temperature and humidity control system has high anti-interference...

According to the power and current selection, the rated voltage of bai24V, multiplied by the rated working du current, zhi is the rated power that needs to be selected.Due to the high efficiency of switching power supply, the switching power supply can generally reach more than 80%. Therefore, in the selection of its output current, the maximum absorption current of the electrical equipment should...
