Description: A mini optocoupler isolation, signal level conversion module. Suitable for general level conversion, such as from 24V to 5V level. 24V side can be connected with long wire button, the output side is connected to the MCU IO pin. The highest signal frequency is 2KHz. With input signal indicator, reverse connection protection diode and current limiting resistor. The output end is an optocoupler triode, and the NPN output can be continued. The output terminal has current limiting resistance, and can not directly drive the relay module and other high current equipment. Specification: Size: Approx. 7.4(Width) x 25mm(Length) Input signal voltage: 3.3V Output signal voltage: 3V~32V DC Output signal type: NPN Signal frequency:
