ALLNET Brick'R'knowledge I2C DA converter
D/A converter Brick: Via the I2C bus you can output a value between 0..4095, which is then converted into a proportional voltage. The block can be configured for two different addresses, so that a maximum of two such blocks can be connected. Another special feature is the connector strip on the front, which allows different voltage ranges to be set. A maximum of 20mA can be taken (but the output voltage changes). The assignment for the voltage setting is printed on the back.
