The DIN rail-mountable devices are optimised for use in highly deterministic EtherCAT networks with extremely short cycle times.
Ensuring fast control in the case of cable interruptions or the establishment of Hot Connect group connections, EtherCAT media converters are useful wherever EtherCAT needs to be transmitted over long distances or increased electromagnetic interference is to be expected as well as in the realisation of data links to rotating parts such as slip rings, or of data light barriers in high-bay warehouses with carriages that travel long distances.
EtherCAT media converters for Industrial Fast Ethernet (100 Mbaud) overcome the shortcomings in conventional Ethernet media converters that do not meet the requirements for a highly deterministic EtherCAT network.
The devices from the CU1521 series convert optical fibre physics to copper physics and vice versa. While the CU1521 is suitable for multimode, the CU1521-0010 is ideal for single mode fibre optic and therefore significantly longer transmission links. Using the CU1561, POF (Plastic Optical Fibre), which is simple to install in the field, can be converted to copper physics.
The CU1521 is useful in applications where EtherCAT is to be transmitted over distances of up to 2,000m between two stations or where increased electromagnetic interference on the bus is to be expected. The CU1561 is suitable for situations with increased electromagnetic interference and where simplified wireability is demanded.
The EP952x devices are conceived for applications requiring IP 67 protection. Both media converters are suitable for multimode fibre optic cables. In addition to the copper branch, the 2-channel EP9522-0020 enables further optical fibre topologies to be configured via the second optical fibre port, while the single-channel EtherCAT Box EP9521-0020 is used for direct transfers between the two media.
Key features of CU1521 and CU1561 EtherCAT media converters:
- DIN rail-mountable devices implemented with IP 20 protection
- Operates bi-directionally and collision-free with constant delay and can be diagnosed as independent EtherCAT devices
- Enables fast link control and safe closing of the EtherCAT strand even in the event of a fault
- Can be configured via a switch since the transfer direction is relevant for the bus
- Switch is also used to set the ‘Link Loss Forwarding’ function for the support of a ‘normal’ 100 Mbaud Ethernet network
