thereby controlling external devices or circuits.
(1) Simple and practical: The structure of the switch controller is simple, easy to implement, and can be easily embedded into various control systems. Its working principle is intuitive and easy to understand, without the need for complex calculations and adjustment processes.
(2) Low cost: Due to the simple structure of the switch controller, the manufacturing cost is relatively low. This makes the switch controller highly competitive in some cost sensitive situations.
(3) Suitable for large inertia systems: The switch controller is suitable for some systems with large inertia, such as large heating furnaces, refrigeration equipment, etc. In these systems, due to the slow response speed of the system, the switch controller can gradually adjust the system output by continuously switching the output state, achieving a relatively stable control effect.
4、 The difference between PID controller and switch controller
control accuracy
The PID controller has high control accuracy and can achieve precise control of the system output. The control accuracy of the switch controller is relatively low, and can only achieve rough control effects. In some situations where high control accuracy is required, such as temperature control, pressure control, etc., PID controllers have obvious advantages.
responsible for processing signals from on-site sensors or driving actuator actions. For example, they may need to cooperate with devices such
as BANNER travel switch T30UIPB to receive their transmitted position signals; Or by controlling components such as Burkert solenoid valve 00131421, the on/off of fluid media can be precisely managed.
these modules integrate more complex logic processing capabilities. The core task of a pressure switch is to detect whether the pressure
has reached a preset threshold and output a switch signal. Its function is highly specific and fixed. And modules 3A99695H01 and 1
C31219G01 have the ability to comprehensively judge multiple such switch signals and transmitter signals (such as transmitter 1066-P-HT-60),
and output complex control instructions according to internal logic.
