I2C-RL812MA
Updated: Jul 16, 2012
Description
The I2C-RL812MA is a board for remote 8-relay expander for I2C bus based on PCF8574A. Making it ideal as relay outputs expander for I2C bus. It is designed to compatible with most micro-controllers. The board supports 100kHz I2C bus frequency. Address by 3 jumpers for use of up to 8 devices (up to 16 with I2C-RL812M and I2C-RL812MA). An operating logic supply voltage is 2.5 - 5.5 V with inverse polarity protection. A relay supply voltage is 9 - 13 V with inverse polarity protection. Relay contact rating is 10A(120VAC/24VDC) or 6A( 250VAC) at 100,000 life cycles. The board has relay power-on protection. PCB size fits on DIN-Rail mount supports, 72 x 87.5 mm.
