thereby controlling external devices or circuits.
PWM controller is a control strategy that adjusts the duty cycle of pulses to control the average level of the output signal. It controls the required output by periodically switching the power supply and adjusting the ratio of switching time to off time. PWM controllers are widely used in application scenarios that require simulation of continuous signals, such as DC motor speed control, LED brightness adjustment, audio amplifiers, etc.
principle
The principle of PWM controller is to control the voltage and current in the circuit by changing the width of the pulse. In PWM signals, the high-level duration is longer and the low-level duration is shorter, which changes the power output in the circuit. Specifically, when the PWM signal is at a high level, the switches in the circuit will open and current will flow through the load; When the PWM signal is at a low level, the switch will close and the current will stop flowing. Therefore, by changing the time ratio of the high and low levels of the PWM signal, it is possible to control the voltage and current in the circuit.
application
PWM controllers are commonly used in application scenarios that require simulation of continuous signals, such as DC motor speed control, LED brightness adjustment, audio amplifiers, etc. In these applications, PWM controllers can accurately control the average level of the output signal by adjusting the duty cycle of the pulses, thereby achieving precise control of the equipment.
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 1C21219G01 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.
