The module allows to control the actuators consuming the current up to 10 A using the microcontroller's ports or any starting set (includingArduino,Raspberry PiandSTM32Discovery). Optoinsulation seperates the control signal from the part associated with the power relay, thereby providing work safety for the control system.


The product is compatible with Arduino

For relay control, onlyu a digital control signal from leads of the Arduino is needed.


For proper operation, connect the power of the relay's coil and the digital control signal. Leads are the standardstrap goldpinwith pitch of 2.54 mm, which enables connection with the connecting cables.
