8-way relay module/5V10A optocoupler isolated anti-interference EL817 optocoupler

• This module is perfect for use with projects that require regulating several higher voltages.
• This 8-channel relay module has the ability to turn on 30V DC and up to 250V AC.
• This enables you to incorporate device control, such as turning on lights from a distance or starting up systems when the module receives a signal.
• Several different sources, including the majority of common microcontrollers, can provide this signal.
