NUMATO LAB Relay Shield - 4 Channel

Numato Lab's 4 Channel Relay Shield provides an easy way to control high voltage/current electrical and electronic devices. It has four 12V DC SPDT mechanical relays that can switch up to 10A DC or 12A AC current load. Individual LEDs available on the board indicates the state of the relays. All contacts on each relay are brought out separately on screw terminals. External voltage provides power supply to this shield, connect a 12V DC voltage to the external screw terminals on the board with correct polarity. Some of the possible uses of this shield include - Home Automation - Lighting Control - Garden Equipment Control - Industrial Automation - Test Fixtures - DIY and Hobby Features - Arduino Uno, Arduino Mega compatible shield. - 4 SPDT mechanical relays. - ULN2003 IC is to drive relays. - Individual LEDs are available for indicating the relay state. - Screw terminals are equipped for connecting external devices. - Arduino stackable female headers are available for shield extending purpose. - Small size, Low cost and Light weight.
