The PCI 8132 and 8134 from ADLINK are 2 and 4 axis stepper and servo motion control cards for the PC based systems. The cards can generate high frequency pulse trains to control motor speed, the number of pulses controls the motor position.

Output options include DIR/OUT and CW/CCW modes for an easy way to control numerous stepper and servo motors. An incremental encoder interface is a feature on all axes of the cards, to correct positional errors generated by inaccurate mechanical transmissions.
