Optically isolates and converts unbalanced half- or full-duplex RS-232 signals to optically isolated and balanced full-duplex RS-422 or 2-wire half- or 4-wire full-duplex RS-485.
Switch-selectable data rates between 2400 bps and 19.2 kbps.

Power up to six of the converters with our optional DIN Rail 12-VDC Power Supply (PSD100).
