Main highlights

•NOYITO 1-Channel PC817 Optocoupler Isolation module adopts 5.0 pitch screw terminals for easy wiring . The module can play the role of isolation when the output level of the single-chip microcomputer drives the inductive devices such as motors and motors, and protect part of the circuit of the single-chip microcomputer against interference.
•The module can be used for high-voltage detection. For example, if the output signal level of a sensor is 12V, and the voltage of the microcontroller is 5V, this module can be used for isolation detection.
•The module can also be used for current amplification. For example, when the output current of the microcontroller is too small to drive certain circuits, this module can be used for amplification.
•Input signal voltage: 3-5V / 12V / 24V (optional).
•Output signal voltage: wide voltage, suitable for DC1.8 - 24V.
