Digital Switching Board of 5VDC SPDT Relay Module with Optocoupler

Specification

• Product code : GT-D001
• Power supply : 5VDC
• PCB Size : 50mm x 35mm
• Digital Control via Microcontroller using 5VDC/GND.
• Can attach between Remote kit & Market Board which we mentioned in Remote kit's manual.
• Using an optocoupler in a relay circuit provides electrical isolation between the input and output sides of the circuit. This isolation is achieved by using a light-emitting diode (LED) on the input side and a photodetector on the output side, which are optically coupled.
• This circuit allows you to control the relay using a microcontroller or other low-voltage signal source while providing electrical isolation between the control circuit and the high-voltage side of the relay.
• If you want to control 220v AC, Remove the resistor what we have soldered with LED on PCB.
