WHAT IS A RELAY?
A Relay is an Electrically switching/controlling device. Relay is frequently used in Automatic control system/Circuit. Simply , it is an automatic Switch to controlling a high-current circuit with a low-current signal.

The features of 1-Channel Relay Module Arduino are as follow:

i. Good in safety. In power system and high voltage system, the lower current can control the higher one.

ii. 1 Channel Relay Module Arduino operating DC 5 voltage
iii. 1-channel Relay Module High Voltage system Output
iv. Wide Range of Controlable voltage.
v. Able to control high load current, 240V, 10A
vi. With a normally-open (NO) contact and A normally-closed (NC) contacts
