V Pin Relay Wiring Diagram
V Pin Relay Wiring Diagram. Warning: do not touch any wires that are connected to mains voltage. We just need: Connect an Arduino's pin to the IN pin of the relay.
If you want to keep them isolated then you have to provide an independent power supply through the JD-VCC pin. The six pins on the left side of the relay module connect high voltage, and the pins on the right side connect the component that requires low voltage—the Arduino pins. Place the relay's rated coil voltage on these terminals.
I go over what each contact of the relay is for, and.
Arduino GND pin - Relay module GND pin.
Instructions for wiring a standard automotive relay with descriptions of the pin-out and the schematic. On the other hand, this diagram is a simplified version of the structure. The marlin configuration you can find in the PDF manual, you.
