We recommend the model BMSD‑20Modbus

The model BMSD is outdated, production discontinued. We recommend using new models instead. Please, check the list of present models here https://smd.ee/brushcontroller.htm

BMSD is a DC brush motor controller with RS-485 communication interface. It is designed to control speed and direction of a low power DC brush motors. Motion parameters can be changed by inputs or by commands via RS-485. There is a speed stabilization function for motors with encoder.

Smooth motor start and stop is provided by internal potentiometers or commands via RS-485. Motor speed can be adjusted by internal or external potentiometer, by analog voltage signal or by command via RS-485. Motion direction is controlled by digital inputs or by command via RS-485.

The controller is intended for low power DC motors with rated continuous current below 12 Amp.
