Pressure controller The pressure controller is a specialized pressure control instrument used in industrial process measurement and control systems, often referred to as a pressure switch. It uses pressure as the control signal and achieves automatic pressure control through electrical switches. The pressure controller can act when the controlled pressure exceeds or falls below the…
The control module is a logical function module in the power system that implements operational control for devices within the home local area network. This definition originates from the power industry standard DL/T 1398.1—2014 “Smart Home System – Part 1: General Principles” [1]. Its core functions include signal conversion and delay control, which can…
The term “distributed control system” was derived by translating the product name of a foreign company. Due to the numerous manufacturers and varying system designs, as well as the diverse functions and features of each system, the naming of these products also varies. In China, there are different names for the product, the most…
A circuit breaker is a switch device that can close, carry and open the current under normal circuit conditions, and can also close, carry and open the current under abnormal circuit conditions within a specified time. Circuit breakers are classified into high-voltage circuit breakers and low-voltage circuit breakers based on their application scope. The boundary…
