12V 30A T Type Relay Module with on board Optocoupler has 30A switching capability and suitable to both DC and AC. Significantly it can be used to control one 240V power appliance directly from Arduino, Raspberry Pi, and other microcontrollers or low voltage circuits. Perfect for switching 240V appliances – lights, fans, etc, and even high power motors at lower voltages.

Also electrical relays got their start in application to telegraphs. American scientist Joseph Henry is often cited to have invented a relay in 1835 in order to improve his version of the electrical telegraph, developed earlier in 1831.However, an official patent was not issued until 1840 to Samuel Morse for his telegraph, which is now called a relay.
