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

The KL2542 Bus Terminal enables direct operation of two DC motors. The speed or position is specified by the automation device via a 16-bit value. The output stage is protected against overload and short-circuit and galvanically isolated from the K-bus. Both channels indicate their signal states by means of light emitting diodes for simple and quick local diagnosis. Connection of an incremental encoder enables a simple servo axis to be realized.
