The Kitronik Relay Control Breakout Board allows a low power logic level device running at 5V to operate a relay capable of switching high current loads up to 16A 250VAC or 16A 30VDC. This enables low power microprocessors to control large, power-consuming devices safely and effectively.To operate the board, connect a constant 5V power supply and a signal input. When the signal input is high (above 2.1V), the relay and onboard LED indicator activate, closing the normally open relay circuit. High current output drive (16A) LED indicator shows relay operation Compact dimensions: 48mm length, 38mm width, 26.5mm height Connections: GND – Ground / zero volts Vcc – 5V power input SIG – Signal input (above 2.1V activates relay) LOAD – Relay output terminals, connected when relay is on Possible applications include driving motors or lights from a microcontroller.Caution: This board can be used with mains electricity but should only be handled by qualified persons.Contents: 1 x Relay Breakout Board supplied in a bag.
