I2C Relay Board 8-Channel using MCP23008

Brainstorm Technologies has developed the 8-channel I2c Relay Board, It is a fully optically isolated relay board. The microcontroller side and the relay coil power supply side are fully isolated using optocouplers, Even the GND planes of both the sides are separate to provide full isolation.

This board is using the MCP23008 IC to make it I2C Controlled Relay Board. by using only 2 PINs SCL and SDA of microcontroller, maximum 64 relays can be controlled this is possible due to the onboard addressing DIP switch. by changing the 3 pole DIP switch we can address up to 8 relay board and each relay board having 8 relays so total 64 relays can be controlled.
