This is an I2C relay board. The board for remote 8 relays expander for i2c bus based on PCF8574. Making it ideal as relay outputs expander for i2c bus. It is designed to compatible with most microcontrollers.
The board supports 100khz, i2c bus frequency. Address by 3 jumpers for use of up to 8 boards or 64 relays. Also they can be connected up to 16 boards or 128 relays, see more details in board's datasheet.
An operating logic supply voltage is 2.5-5.5v with inverse polarity protection.
A relay supply voltage is 9-13v with inverse polarity protection, 12v is recommended. Relay contact rating is 10A(120Vac/24Vdc) or 6A( 250Vac) at 100,000 life cycles. The board has relay power-on protection.
To prevent damage to the board. Don't plug and/or unplug I2C cables on the board while a power supply still turns on. Turn off a power supply before plug and/or unplug I2C cables on the board.
