Offers digital readouts. Features : pulse multiplication: to improve the resolution of the dro pulse multiplication technique has been used i.e. Input module counts the leading and trailing edges of the pulse trains from ch-a and ch-b of the encoder. Hence the cro counts (pprx4) per revolution of the encoder. Start from preset : a preset value can be set and reading will start from the preset value. Scaled reading : a scale factor can be set within the range from 0.00001 to
