4-port + 2kV insulation! High-reliability model for industrial USB ⇔ serial conversion.
The ULI-314DC is an industrial USB-to-serial converter that can add four RS-232/422/485 ports to a PC's USB port. It supports USB 2.0 (up to 480Mbps) and serial communication at speeds of up to 921.6kbps. With 2kV port-to-port isolation, it provides electrical separation between the upstream PC and downstream devices, as well as between each port, protecting equipment from voltage surges and ground loops. It features a robust metal housing, is compatible with DIN rail and panel mounting, and operates in a wide temperature range of -40 to +85°C. It has obtained UL Class 1/Division 2 certification, making it ideal for harsh industrial environments. It also supports industrial protocols such as Modbus RTU, providing reliable communication for control panels and field services.
