4-port + 2kV isolation! Industrial USB ⇔ RS-422/485 converter compatible with panel mounting.
The ULI-344TC is an industrial USB-to-serial converter that can add four RS-422/485 ports to a USB port. It supports USB 2.0 (up to 12 Mbps) and serial communication at speeds of up to 921.6 kbps. With 2 kV optical isolation, it provides electrical separation between the upstream PC and downstream devices, as well as between each port, protecting the equipment from voltage surges and ground loops. It features a robust metal housing and is suitable for panel mounting, making it ideal for control panels and factory networks. It also supports industrial protocols such as Modbus RTU, providing high-reliability communication for simultaneous connections of multiple devices in the field.
