The Single Channel Relay Module is a convenient board which can be used to control high voltage, high current load such as motor, solenoid valves, lamps and AC load. It is designed to interface with microcontroller such as Arduino, PIC and etc. The relays terminal (COM, NO and NC) is being brought out with screw terminal. It also comes with a LED to indicate the status of relay. Specification: Digital output controllable Compatible with any 5V microcontroller such as Arduino. Rated through-current: 10A (NO) 5A (NC) Control signal: TTL level Max. switching voltage 250VAC/30VDC Max. switching current 10A Size: 43mm x 17mm x 17mm
