The relay module is a digital switch to control much higher voltages and currents which are out of the abilities of your Arduino or microcontroller. Whenever switching a device with high voltage or draw high current, a relay will be needed.
When a logic input is given, the relay will switch to allow current to flow or cut-off dependent on the wiring. A relay usually consist of a coil, 1 common terminal, 1 normally closed terminal and one normally open terminal. The common terminal and the normally open terminal will be connected when the coil is energized. The VCC and JD-VCC need to be connected with jumper when using this module.
- Operating voltage of 5V
- Capable of conducting 250VAC@10A or 30VDC@10A.
- Connect JD-VCC and VCC with jumper
