Description:
This is DC 5V 4 Channel Relay Module USB Control which can switch up to 10 Amps. Relays terminals (C, NC, NO) are accessible through screw terminals which makes wiring up the board very easy.
The relay is safely driven by transistor BC 547 hence your input device, such as Arduino, is protected from the relay circuit. There is fly back diode which will further protect your microcontroller from relay kickback.
