Description of the DC brush motor speed controller BMD-20DIN

The device BMD-20DIN is a speed controller for a DC brush motor. The controller is designed to control DC brush motors with a supply voltage of up to 24V and a power of up to 500W. It is possible to control the speed of a DC brush motor with an analog signal 0...5 VDC or with a built-in or external potentiometer. Acceleration, direction and deceleration are set by internal regulators included in the design of the device.

The DC brush motor speed controller BMD-20DIN performs the following functions:

  • start and stop a DC brush motor by a button on the front panel or by an external signal;
  • analog regulation of speed of a DC brush motor;
  • control of the rotation direction with a button on the front panel or an external signal;
  • setting the ration of acceleration and deceleration;
  • motor overload protection with adjustable rated current;
  • motor short circuit protection;
  • emergency stop of a DC brush motor "HARD STOP" in the event of a break in the electrical circuit of the protection circuit, function of safe stop "Safe Stop 1";
  • temperature protection of power stages.
