GE VMIVME2510B Programmable controller PLC
According to the set negative pressure target value, each room can achieve the negative pressure gradient control target through PID control.
Through control and calculation, PLC can control the exhaust fan and forced draft fan. The exhaust fan interlocks with the air supply fan of the air conditioning unit, and the start and stop of the air supply fan and the exhaust fan are synchronized. The exhaust fan controls the operating frequency of the exhaust fan through PID calculation according to the differential pressure sensor set on the main air duct and the comparison between the set value and the measured value.
PLC uploads various data to the touch screen (HMI), which is used to display the operating status of the negative pressure laboratory equipment, the current negative pressure, fault information, real-time curve, historical curve, etc. in each laboratory. Set the target negative pressure for each room, set the upper and lower limit alarm value of negative pressure, and display the situation of each room.
In the control scheme of the clean ventilation system, RPC2000 series PLC of Lanpufeng Company is used as the hardware platform. Through a set of PLC, the control function of the clean exhaust system in 15 negative pressure isolation laboratories is realized. The CPU module is equipped with digital input and digital output, and the analog input and analog output are connected through the expansion module. The specific configuration of the control system is as follows 2.1 CPU module RPC2107N。
Industrial control products are basically available. If you can’t find any products, you can contact the customer service to help you find them.
