Product Description

The Beckhoff CU1521-0010 is a significant plug-in module in the Beckhoff EtherCAT product line that enables direct media conversion from RJ45 copper physics to single-mode fiber optics and vice versa.

This EtherCAT media converter combines single-mode glass fiber (9/125µm SM) and a minimum Category 5 shielded Ethernet/EtherCAT cable to ensure stable and accurate data transport across industries. The unit features a dependable bus interface with one SC Duplex and one RJ45; the communication distance supported is up to 20,000 meters for 100BASE-FX and 100 meters for 100BASE-TX, which is critical for complex networking. The CU1521-0010 uses the EtherCAT protocol to transfer data at a rate of 100 Mbps with an estimated delay of 1 µs, demonstrating its ability to handle high-speed data. A 24V DC input with a range of 18 to 30 V DC is used to meet power requirements via a 3-pin connection, ensuring a dependable power supply in any industrial environment. This unit is compact, measuring 35 mm x 98.5 mm x 76.5 mm, and its flexibility allows it to be fitted in any position. The device functions properly at temperatures between 0 and 55 °C and can be transported and/or stored at temperatures ranging from -25 to + 85 °C. It meets the necessary environmental standards for vibration (EN 60068-2-6/EN 60068-2-27) and shock (EN 60068-2-6/EN 60068-2-27) as well as electromagnetic compatibility immunity/emission (EN 61000-6-2/EN 61000-6-4).

The IP20 protects against the enclosures and ensures safe usage in different industrial systems. Two other features that add flexibility to the CU1521-0010 are its ability to operate in conditions with up to 95% relative humidity without forming condensation and the rotary switch used to set the unit manually. This switch also makes it easy to switch between operational modes and supports Link Loss Forwarding for standard Ethernet operations to offer customized solutions in line with the needs of the network. A one-year warranty accompanies this product at Wake Industrial.
