Streamline controls has introduced digital dc stepper drives, digistep. It has been designed to meet various motion control applications. These intelligent pwm drives operate on inherently reliable microcontroller technology with industry proven power module. These drives havecome with maximum 12 amperes/phase and are guaranteed against short circuit at outputs. These drive come for unipolar as well as bipolar dc stepper motors. These are modular and compact in size. They also consist of three digital inputs, two digital outputs, one optional high speed input for closed loop application and rs-485 serial port for interface with external control systems.
