8 Channel 1A Relay Board Controlled Via Serial or I2C

The RLY08 provides 8x volt free contact relay outputs with a current rating of up to 1A each. The board requires a 5V supply and has an exceptionally low maximum current consumption of approx. 100mA with all relays on. The relays are SPCO (Single Pole Change Over) types. The normally open, normally closed and common pins are all available on the screw terminals.

There are two operating modes for the module board, I²C and serial mode. The mode is set via the mode pin and is connected to 0V ground for serial mode and unconnected for I²C mode. The module board can be expanded to up to 8 modules via either serial or I²C bus.
