Product catalog summary

Overview: This document provides technical specifications and operational guidelines for a motor-speed control device designed for brush sticking direct current motors operating at 24VDC. The device is compatible with DIN-rail standards EN 50022 and EN 50035.

Technical Specifications:

Input Circuit: Rated voltage is 24VDC with a threshold voltage range of 19V to 35VDC. The input current during rated voltage is 10mA, indicated by a 3mm yellow LED.
Output Circuit: The switching voltage range is 15V to 35VDC, with a maximum permanent load current of 5A and an impulse current of 10A. The switching frequency is 50 Hz at 5A, with a short-circuit current sensing capability of 95A and a switch-off time of 80 - 400 µs after a short-circuit.
Other Data: The device operates within an ambient temperature range of -20°C to +50°C and is housed in a plastic case with IP20 protection. It includes overload protection, short-circuit-proof features, and temperature monitoring. The device complies with VDE 0110 and 0160 standards in parts.
Physical Dimensions: The dimensions are 22.5mm x 75mm x 105mm, with a construction width of 22.5mm. It can be installed in a snap-on, addable position and connected via screw terminals for single wire (4mm²) or fine wire (2.5mm²).

Operational Description: The device controls motor speed by monitoring current levels. If the motor current exceeds a set value (Tr1), the device dynamically brakes and switches off the motor. A temporal fade-out function (Tr2) prevents response during motor run-up. If the motor current exceeds the set value during operation, the motor switches off and remains off until a reset is performed. The message output (I-OUT) is set to HIGH (+VCC), and a red LED (ERR) lights up to indicate an error.

Reset Functions: The device can be reset by setting inputs A1 and A2 to LOW (0V) and input A3 to HIGH (+VCC).

Manufacturer: KALEJA GmbH, D-73553 Alfdorf.

When blocking the control the motor for incorrect high current. If the motor current rise over the set Value ( Tr1 ), the control switch off the motor with dynamical braking. By that at run-up of the Motor the Current Evaluation don´t respond, is a temporal adjustable fade-out function ( Tr2 ) of protection during that time active. Rise at operation the Motor current over the setting Value, the Motor will switch-off and stay suspended till the next RESET. The Message Output ( I - OUT ) will set on HIGH (+VCC) . LED red ( ERR ) lightning. RESET-functions: - LOW (0V) at inputs A1 and A2. - HIGH...
