Our AZ-Delivery relay modules switch quickly and reliably many switching operations. Thanks to an additional transistor, the module can be switched with most microcontrollers with little current. The relays used are generously dimensioned to allow permanent operation even under difficult operating conditions.

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

The relays are commonly used in remote control, communications, mechatronics, power electronics, etc. They can also be used to isolate high power voltage/current electronics (such as AC or DC motors, AC devices, etc.) from microelectronics (microcontrollers, sensors, etc.).


  • Compact design and large capacity: this 16-relay module can switch high currents up to 5A.
  • Compared to other relay modules, the AZ-Delivery relays are generously sized to allow durable operation even in adverse operating conditions.
