Microflex, 101-0090, RS-232 to 2-Wire RS-485 Converter, Isolated, DIN Rail Mounted
The 101-0090 RS-232 to RS-485 Converter provides a simple, galvanically isolated interface between an RS-232 serial port and 2-wire RS-485 devices. It features automatic direction control to switch between receive and transmit so RTS (Request-To-Send) is not needed. Isolation is important for systems where the ground loop may be broken allowing for large common mode voltage variation.
