One optocoupler isolation module adopts 5.0 pitch screw terminals for convenient wiring. The module is suitable for isolating and anti-interference protection of some circuits of the microcontroller when the output level of the microcontroller is used to drive inductive devices such as motors. The output level of the microcontroller is low, and the driving voltage of the driven module is high for level matching. For example, if some PLC inputs require 24V voltage, this module can be used for conversion.
Used for inverters, which can invert the input signal and output it. Used for high voltage detection, such as when the output signal level of a sensor is 12V and the voltage of a microcontroller is 5V, this module can be used for isolation detection. When the output current of a microcontroller is too small to drive certain circuits, this module can be used for current amplification. The module adopts optocoupler isolation, which is stable, reliable, and has a long service life.
