EL817 8 Channel Optocoupler Isolation Module

 

EL817 8 Channel Optocoupler Isolation Module.This module is useful for connecting digital systems (such as a 5V microcontroller) to a high voltage or noisy system. It electrically isolates a controller from a high-power system using an opto-isolator IC. It isolates the systems, creating a type of electrical noise barrier between devices. This board can be used in high noise environments, such as isolating the signal between the driver and microcontroller.
