I2C-RL812MA





I2C Relay 12V 10A PCF8574A

I2C-RL812MA


This is an I2C relay board. The board for remote 8 relays expander for i2c bus based on PCF8574A. 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.

Features:
  • 8 relays on board
