16-Relais Modul 12V mit Optokoppler Low-Level-Trigger kompatibel mit Arduino Select quantity discount:3x relays Thanks to ATmega328 microcontroller alsoOur 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
