Description

It can be operated up to 8 analog cards on the I2C bus. The following addresses are adjustable by jumpers:
PCF8591: 144, 146, 148, 150, 152, 154, 156, 158
So you can read up to 24 analog signals and output 8 analog signals.

The reference voltage source of 2.5 V is used LM334.
About the voltage divider 10 ohms and 31.6 ohms, voltages from 0 - 10V read.

To increase signal and impedance conversion, the output voltage of the PCF is raised 8591mit a standard operational amplifier LM324. For line compensation in the repatriation is led out to the OP to separate terminals.

Dimensions of the circuit board 60 x 50 mm.
