Distribution cabinets are scattered throughout different factories or regions, making 1/0 control distribution cabinets more dispersed. In order to better reduce the labor efficiency of employees and achieve fully automatic supervision without anyone on duty, the distribution cabinet needs to be controlled to remotely collect data and centrally monitor the distribution cabinet. According to the local or long-distance fully automatic control of key distribution cabinets, the on-site distribution cabinets are monitored in all directions and real-time to indicate the production process, providing the necessary data for production manufacturing, production scheduling, and management methods. Below, Wuxi Shengminghua will introduce some knowledge about distribution cabinets.

Most distribution cabinets are used for logical control of centrifugal water pumps and distribution pumps. Closed loop control is suitable for controlling the working pressure of water output, while logical control is the traditional main purpose of programmable logic controllers (PLCs). PLC can not only collect switch data signals, but also perform logical control. The modular function of the distribution cabinet is complete, which can expand the PLC acquisition and control module to ensure real-time data transmission; In addition, PLC has the characteristics of high compatibility mode, strong anti-interference ability, and easy expansion of distribution cabinet function, making it the preferred controller for industrial production control distribution cabinets today. Therefore, the wastewater treatment distribution cabinet is relatively highly integrated and modular in design, which can meet the requirements of data acquisition, transmission, computation, and distribution cabinet data resolution.
