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 EJ7342 has two channels that indicate their signal state via light emitting diodes. The LEDs enable quick local diagnosis.
