BLSD-5704 - DC brushless drive with RS-485

BLSD-5704 is a complete DC brushless drive with RS-485 communication interface. It consists of brushless motor SM57L114 with Hall sensors and controller BLSD-20. The motor speed, direction, start/stop and acceleration/deceleration can be controlled by commands via RS-485 or by internal inputs - analog control for speed and acceleration regulation and digital inputs for start/stop and direction.
