B&R X20AI2322
2 analog inputs, 0 to 20 mA or 4 to 20 mA 12-bit digital converter resolution The module is equipped with 2 inputs with 12-bit digital converter resolution. It is possible to select between the two current ranges 0 to 20 mA and 4 to 20 mA. This module is designed for X20 6-pin terminal blocks. If needed (e.g. for logistical reasons), the 12-pin terminal block can also be used.
