I/O Control Stepper Driver 0-2.2A 18-36VDC for Nema 11, 14, 17 Stepper Motor

This is a stepper driver support I/O (Input/Output) control modes. It delivers superior performance with a current range of 0–2.2A and an operating voltage of 18–36VDC, making it ideal for Nema 11, 14, 17 stepper motors.
This advanced 32-bit DSP-controlled stepper driver delivers high performance at competitive cost. It features 3 opto-isolated digital inputs (5V/24V compatible) with flexible wiring options. The innovative resonance suppression algorithm ensures smooth low-to-mid speed operation, while precise current control minimizes motor heating. Dual start-stop modes and comprehensive protection (over-voltage/current, error equalization) ensure reliable operation for industrial automation and precision motion control.
