The Allen-Bradley 1771-NB4S Analog Module is a robust solution for connecting analog signals to programmable logic controllers, featuring four channels with two 4-20mA inputs and two 0-25mA current outputs. This intelligent block transfer module draws a backplane current of 1.4A and offers an output resolution of 3.2 µA per bit (13 bits unipolar), with impressive output overvoltage protection rated at 140V AC (RMS). Engineered for precision and reliability, the module boasts a full-scale settling time of 500 µs and maintains an accuracy of 0.01% at 25 °C, functioning effectively within a temperature range of 0 to 60 °C in non-condensing environments.
