Introduction
Copper – optical fiber - media converter with 2 x M8 EtherCAT/Ethernet port and 1 x optical fiber multimode EtherCAT/Ethernet port
The EtherCAT/Industrial Ethernet module EP9521-0020 for Industrial Fast Ethernet/100 Mbit/s serves as media converter from optical fibre to copper and vice versa.
The media converter is suitable for multimode fibre-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 fibre | optical fibre 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.
The load voltage UP is not used in the input module, but may be connected in order to be relayed downstream.
