UTS-31TBi
The Isolated USB to serial interface adapter features 2.5kV isolation to ensure these serial devices via the terminal block wired require long range or multi-drop capabilities won’t be damaged between the PC and serial applications. All configuration and electrical interface selections are handled through the driver, eliminating the need to open the enclosure to set jumpers or switches. The serial port is software configurable for RS-232, RS-422, and RS-485 with the electrical interface settings maintained locally, allowing the host computer to be repaired or upgraded without reconfiguring the serial port. Additionally, the isolated adapter can be configured at one computer and deployed to other computers.
