420MA Current Stepper Motor Driver
Product Overview
The 420MA current stepper motor driver provides 4-20mA analog current-based speed control for NEMA17 and NEMA23 frame motors. This driver accepts the industry-standard 4-20mA current loop signal commonly used in process control and industrial automation, converting the current signal directly to motor speed for applications requiring long-distance signal transmission or compatibility with existing 4-20mA control infrastructure.
Operating on 12-48V DC with output current from 1.0A to 4.5A, the 420MA driver provides excellent noise immunity due to the current-loop interface, making it ideal for electrically noisy industrial environments where voltage signals would be susceptible to interference.
