KL2552 | 2-channel DC motor output stage 50 V DC, 5 A
The KL2552 Bus Terminal enables direct operation of two DC motors. It is galvanically isolated from the K-bus. The speed is specified by the automation device via a 16 bit value. Connection of an incremental encoder enables a simple servo axis to be realised. Typical motor parameters can be set in order to avoid critical conditions of the DC motor. The load can be protected by limiting the maximum values for speed, torque and acceleration. The output stage is protected against overload and short-circuit. The Bus Terminal contains two channels that indicate their signal state by means of light emitting diodes. The LEDs enable quick local diagnosis.
