FBs-2ARTD4 is one of the Analog and Temperature mixed input modules of FATEK FBs series PLC. For analog input it provides 2 channels A/D input with 12 or 14 bit effective resolution. Base on the
different jumper settings it can measure the varieties of current or voltage signal. The reading value is represented by a 14 bit value no matter the effective resolution is set to 12 or 14 bit The output code also can be configured as unipolar or bipolar which makes the relation of input code and real input signal more intuitive.. In order to filter out the field noise imposed on the signal, it also provides the average of sample input function.
