8 relay module 5V with optocoupler

AZ-Delivery relay modules  switch many switching processes quickly and reliably. Thanks to an additional transistor, the module can be switched with most microcontrollers with little power. The relays used are generously dimensioned to enable continuous operation even under unfavorable operating conditions.

The optocouplers and diodes protect your controller from damage. The power source can be configured using a jumper on the board.

The relays are widely used in remote control, communication, mechatronics, power electronics, etc. They can also be used to drive high-performance voltage/current electronics (such as AC or DC motors, AC devices, etc.) from microelectronics (microcontrollers , sensors, etc.). to separate.

These relays are not suitable for raspBerry as they only control with 3.3 volts (GPIO output: 3.3 volts, approx. 4mA)
