2-channel DC motor output stage 50 V DC, 3.5 A EJ7342

EJ7342 | 2-channel DC motor output stage 50 V DC, 3.5 A

The EJ7342 EtherCAT plug-in module enables direct operation of two DC motors. It is galvanically isolated from the E-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 common thermal overload warning applies to both output stages together. The EJ7342 has two channels that indicate their signal state via light emitting diodes. The LEDs enable quick local diagnosis.
