Product catalog summary

Overview: The Maxi-MR-5-12 is a motor-speed control module designed for 12VDC brush sticking direct current motors. It is compatible with DIN-rail standards EN 50022 and EN 50035, and is manufactured by KALEJA GmbH in Germany.

Specifications:

Input Circuit: Rated voltage is 12VDC with an input current of 10mA. The analogue input voltage range is 0V to 10VDC, indicated by a 3mm yellow LED.
Output Circuit: The switching voltage range is 10V to 15V DC, with a maximum permanent load current of 6A and a current limitation of 35A until thermal switch-off. Speed and starting ramp are adjustable from 0V to VCC and 50 to 4000ms, respectively.
Power Driver: Utilizes MOS-FET technology.
Environmental Conditions: Operates within an ambient temperature range of -20°C to +50°C, with overload protection, short-circuit-proof, and temperature monitoring.
Standards and Installation: Complies with VDE 0110 and 0160 in parts, can be snapped onto DIN rails, and uses screw terminal connections. Dimensions are 22.5mm x 75mm x 102mm.

Functional Features:

Two-quadrant motor control system for safe ON/OFF switching and controlled driving and braking.
Dynamic braking is achieved by short-circuiting the load in OFF conditions.
Includes short-circuit and temperature protection, with analog input for speed control and starting ramp.

Connection and Operation:

Electrical connections include inputs for dynamic braking, anticlockwise, and clockwise operations.
Switching inputs and states are defined for various configurations, ensuring safe operation with a minimum delay time of 10ms between certain inputs.
Input A1 controls ramp time, while Input A2 controls motor speed, with specific voltage conditions determining output behavior.

Warnings: There is a potential for an undefined state at the output if drive intersections occur at A3 and A4. A delay time of approximately 10ms must be maintained.
