What does PWM controller mean
The Basic Principles and Application Examples of Pulse Width Modulation
Pulse width modulation (PWM) is a highly effective technique for controlling analog circuits using the digital output of microprocessors. It is widely used in many fields, from measurement and communication to power control and conversion.
analog circuit
The value of an analog signal can vary continuously, with no limitations on its time and amplitude resolution. A 9V battery is an analog device because its output voltage is not exactly equal to 9V, but varies over time and can take any real value. Similarly, the current absorbed from the battery is not limited to a set of possible values. The difference between analog signals and digital signals is that the values of the latter can usually only belong to a predetermined set of possible values, such as in the set of {0V, 5V}. Analog voltage and current can be directly used for control, such as controlling the volume of a car radio. In a simple analog radio, the volume knob is connected to a variable resistor. When turning the knob, the resistance value increases or decreases; The current flowing through this resistor also increases or decreases, thereby changing the current value that drives the speaker, causing the volume to increase or decrease accordingly. Like a radio, the output of an analog circuit is linearly proportional to the input.
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 1C31194G02 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.
