The Patton Model 590 Series of RS-232 to RS-232 optical isolators guards your asynchronous equipment from the hazards of ground looping. Plugging directly into your DTE hardware, the Model 590 Series provides 2500V RMS peak DCE/DTE isolation. Both the Model 590A (19.2 kbps max) and Model 591A (115.2kbps max) isolate 4 lines on the RS-232 interface--two of which are selectable by internal jumpers. The Model 592 (19.2 kbps max) and Model 594 (115.2kbps max) isolate 7 pre-wired lines on the RS-232 interface.
