Introduction
The CU1521-0020 is an infrastructure device with optional universal media converter function. Its two SFP slots can be equipped with various and also different SFP modules. It is primarily designed for use in EtherCAT networks, but also supports non-real-time critical Ethernet systems.
The use of EtherCAT is thus possible on the most different transmission paths and distances, depending on which transmission direction is selected and which SFP module is used. The media converter operates multidirectionally and collision-free with constant delay and represents a separate EtherCAT device. Thus, in contrast to standard media converters, the CU1521-0020 ensures fast link control even in the event of a fault, and thus safe termination of the EtherCAT strand and seamless continued operation of EtherCAT.
The EtherCAT transmission direction (RJ45 to SFP, SFP to RJ45, SFP to SFP) or the Ethernet operation can be configured at the device via a rotary switch.
The device is delivered without SFP, but with inserted SFP dust caps.
