Product Description

The Beckhoff CU8850-0000, part of the CU EtherCAT line, works efficiently as a USB extender Rx for industrial applications. This gadget provides an efficient solution for increasing USB reach over longer distances while accommodating a variety of functions that cannot be performed via direct links.

This product has a USB Type-A port for upstream use and an RJ45 interface that supports USB extender Rx. It adheres to USB 1.1 standards, offering baud speeds of 12 Mbit/s for rapid transfers and 1.5 Mbit/s for slower tasks. This ensures compatibility with a variety of devices and applications that require secure data transfer. This device features a status display with two LEDs that provide instant visual feedback on its current actions. The wiring for the USB extension enables for a 50-meter extension, as opposed to the traditional 5-meter limit. The gadget is powered by a 24 VDC supply capable of handling changes ranging from -15% to +20%. A maximum of 300 mA can be delivered without a secondary power source; adding one increases this to 500 mA. The device's power delivery flexibility allows it to meet a wide range of operational requirements while keeping its maximum power usage under 500 mW. This device is designed to withstand extreme conditions, with a storage and transit temperature span of -25°C to +70°C and a humidity capacity of 95% non-condensation.

This device meets stringent industrial vibration and shock handling requirements (EN 60068-2-6 and EN 60068-2-27) and has high electromagnetic interference (EMI) tolerance (EN 60000-6-2 and EN 60000-6-4), ensuring its resilience to difficult situations. With an IP20 designation for solid object protection above 12.5 mm, the CU8850-0000 is safe but lacks waterproofing. This USB extender significantly improves USB functions in complex industrial environments that require long-range connections. A warranty of one year comes standard with this product at Wake Industrial.
