BMD-40DIN brush motor speed controller

The device BMD-40DIN 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.

Motor speed can be adjusted with one of the follow methods:

• internal potentiometer;
• external potentiometer;
• analog signal 0...5 VDC

Parameters of external direction and start/stop signals:

• input type: clean contact;
• maximum resistance of the closed contacts: 4.7 kOhm;
• maximum input current: 0.5 mA;
• "START/STOP" and "DIR" inputs logic can be easily adjusted by a customer: the inputs can operate both as per signal level and as per a front of the signal;
• the default setting is operation as per a front of the signal for "START/STOP" input and as per a level of the signal for "DIR" input.

The DC brush motor speed controller BMD-40DIN 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".
