4~20 mA Current-Adjustable Stepper Motor Driver (420MA)
Product Link
[edit]Description
[edit]The 420MA is a 4-20mA current-adjustable stepper motor driver using industry-standard current loop signals. Miniature size 42.2mm x 42.2mm x 14.5mm, integrates with NEMA17 and NEMA23 motors.
4-20mA input is proportionally converted to motor speed. Default: 4-20mA to 0-300RPM, ideal for peristaltic pumps. Speed range is customizable.
DC input 12-40VDC with 24VDC recommended. Continuous current 1.4A, peak 2.0A. Features direction control, enable input, and debug port. Compatible with existing PLC analog outputs.
