Kit I2C digital output module with optocoupler

Description:

With the I2C output card, 8 digital consumers can be switched.
The output driver TBD62783APG switches a positive voltage up to 30V.

The outputs are galvanically isolated from the I2C bus using optocouplers.

The circuit uses the negative logic because the I2C port expansion module PCF8574 switches on all outputs at voltage.

When controlling, only the desired bit pattern has to be inverted. Or subtract from the 255 desired output value before transferring it to the output card.

Dimension of the circuit board 42 mm x 63 mm
