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 unfavorable 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
