Description

These industrial grade, isolated, USB to serial converters allow you to add two or four RS-232/422/485 ports to your PC. Built to rugged specifications, the BB-USR602 offers 2 kV Port to Port isolation. This means that your upstream PC is isolated from the downstream serial devices and the downstream serial devices are isolated from each other and the upstream PC. Additional features such as a heavy duty metal enclosure with panel and DIN Rail mounting options, high ESD protection, shock and vibration testing, and wide operating temperatures, make them ideal for use in harsh environments. Designed for industrial use, they are also suitable for instrumentation, utilities, and laboratory applications. Full speed (480 Mbps) USB 2.0 support allows connectivity with modern computer technology.
