ENCODER-300
3-Axis Encoder Interface Card

Encoder-300
This board is 3-Axis quadrature encoder interface board for the IBM PC/AT bus compatibles. For each encoder, phase 0, phase 90 and index pulse inputs are provided. Inputs may be single ended(A,B,C) or differential (A+, A-, B+, B-, C+,C-). power and ground connections are provided for encoder use if nedded. Inputs are conditioned by a four-stage digital filters. The maximum input rate in quadrature decode mode is 1MHz. The conditioned input are applied to a 16-bit counter. The counter may be used for quadrature decoding, pules- and direction-input counting, or as a pulse input up/ down counter Application
