EP9521-0020 | EtherCAT Box, media converter, Ethernet/EtherCAT, 100 Mbit/s, 24 V DC

The EtherCAT/Industrial Ethernet module EP9521-0020 for Industrial Fast Ethernet/100 Mbit/s serves as media converter from optical fiber to copper and vice versa. The media converter is suitable for multi-mode fiber-optic cables and is used for direct transfer between the two media. The media converter operates bidirectionally and collision-free with constant delay. It can be diagnosed as a separate EtherCAT device. In this way, unlike standard media converters, it enables fast link control and the safe closing of the EtherCAT strand even in the event of a fault. Since the transfer direction (copper to optical fiber | optical fiber to copper) is relevant for the bus, the device can be configured via a switch. Via this switch “Link Loss Forwarding” for normal Ethernet operation can also be selected.

The EP9521-0020 is useful in applications where EtherCAT transfers over large distances are required or where higher EMC loads on the bus line are to be expected.
