Grove COM22639P module: a powerful switch
The COM22639P module incorporates an HLS8L DC5V electromechanical relay. This makes it possible to switch heavy loads (up to 250 V and 10 A) using the logic signal supplied by your Arduino board. This NO (normally open) relay opens the high-power circuit with a logic low signal and closes it with a logic high.
Grove Relay module: Precautions
This module lets you handle high current, and hence requires you to take a certain number of precautions. If you have the slightest doubt as to how to go about it, don’t hesitate to ask advice from a professional, and always isolate the power to the circuit before working on it in any way.
