KL2542 | 2-channel DC motor output stage 50 V DC, 3.5 A

The KL2542 Bus Terminal enables direct operation of two DC motors. It is galvanically isolated from the K-bus. The speed or position is specified by the automation device via a 16 bit value. Connection of an incremental encoder enables a simple servo axis to be realised. 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.
