-== Relay Module ==
+====== Relay module ======
-The Relay Shield is an Arduino compatible smart module with 4 mechanical relays providing an easy way to control high voltage. The max switching power is 35VDC 70W for each channel. It can be directly controlled by Arduino/Crowduino through digital IOs with external 9V DC supply.
+Relay module is an electrically operated switch of mains voltage. It means that it can be turned on or off, letting the current go through or not. Many relays use an electromagnet to mechanically operate the switch and provide electrical isolation between two circuits.
