Product catalog summary

Specifications:
The document outlines the specifications for a motor control module designed for brush sticking direct current (DC) motors operating at 24VDC. It includes a snap-fit design for DIN rail EN 50022 and features a MOS-FET input circuit with a nominal voltage range of 19VDC to 35VDC. The input current at nominal voltage is 10mA, with status indicators provided by yellow and red LEDs.

Output Circuit:
The output circuit supports a range of switching voltages with a maximum rated load current of 3A. The module allows for adjustable opening time (0.5 to 2.0 seconds) and current control (0.4A to 4A). It includes dynamic braking and can handle an impulse current of 20A for 20 milliseconds.

Further Specifications:
The module operates within an allowable ambient temperature range of -20°C to +50°C and includes overload protection. It complies with DIN VDE regulations 0110 and 0160 in separate parts. The mounting position is modular with a snap-fit design, and the connection type is a spring-type terminal. The case dimensions are 17.5mm x 114.5mm x 99mm.

Functional Description:
The module protects the motor from high currents during locking by switching off the motor after a set time under dynamic braking. A fixed time of approximately 300ms prevents current evaluation during motor acceleration. If excess current is detected during operation, the motor is switched off and remains blocked until a reset is triggered. The reset can be activated by a LOW signal at A1 and A2 or a HIGH signal at A3. The module includes a speed controller adjustable via a potentiometer or analog output SPS (0-10VDC).

Applications:
The module is suitable for various applications, including protection for materials and tools, locking drive belts, conveyor belts, and trucks. It can substitute mechanical reversing relays by deactivating current monitoring, providing protection against excessive pressure and equipment damage.
