Arduino 12V 16 way relay module optocoupler isolation low level trigger

• Our AZ-Delivery relay modules perform a variety of switching tasks with speed and dependability.
• The module can be switched with most microcontrollers using very little current because of an extra transistor.
• The relays that are utilized have ample dimensions that enable continuous functioning, even in challenging working environments.
• Your controller is shielded from harm by the optocouplers and diodes.
• A jumper on the board allows you to adjust the power supply's source.
• Relays are frequently utilized in mechatronics, power electronics, communications, remote control, and other fields.
• Additionally, they can be used to separate microelectronics (microcontrollers, sensors, etc.) from high power voltage/current electronics (such AC or DC motors, AC devices, etc.).
