PC817 4 Channel Optocoupler Module

Description

This module allows you to use a low level signal to control a higher voltage, for example 3V or 5V voltage controlling 9V or 12V voltage. It uses the PC817 opto-isolator. Comes with four channels. Great for use in noisy circuits where signal lines require galvanic isolation

* Input voltage 3.6V to 24V
* Output voltage 3.6V to 30V
* Jumper switches output from high to low
* All four channels are independent and can be used with different voltages at the same time
