The EJ7334-0008 EtherCAT plug-in module enables direct operation of four DC motors and is electrically isolated from the E-bus. The speed is preset by a 16 bit value from the automation unit. The output stage is overload-proof. If direction reversal is not required, up to eight motors can be operated unidirectionally on the EJ7334-0008.
