Standard Analog Input Module, 3 ms Response Time, 0 to +70 °C
249 ohms input impedance Each Opto 22 AD3, AD3T, and AD2T analog input module provides a single channel of optically-isolated current-to-digital conversion. The AD3T and AD2T modules offer additional channel-to-channel isolation. For the AD3 and AD3T modules, the nominal input range is 4 to 20 mA with an under⁄over range capability from less than 3 mA to greater than 35 mA. The AD2T module has a nominal input range of 0 to 20 mA with an under⁄over range capability from less than -1.25 mA to greater than 35 mA
