The Series R325P is a 2-phase stepper motor driver developed by Lin Engineering. It is supplied with +12 to 48 VDC power supply, 0.3 to 3.0 Amps Peak phase current, and full to 256 microstepping resolutions.

The unit comes with an adjustable current and timeout settings, 3 optically isolated control inputs, and 1 optically isolated control output. In addition, the unit features configuration parameters stored in non-volatile memory. It also offers multiple module control, and a built-in control routines for trapezoidal position and velocity movement.
