Overview

The 593 is available in three versions: RS-422, DB-25, and Terminal Block. The 593 Series connects any RS-422 or RS-485 equipment and isolates RS-485 and RS-422 signals.

All Models have selectable Dip switch settings for RS-422/RS-485 applications. The Model 593 Series provides 2500Vrms of isolation and supports data rates up to 115.2 kbps. The Models 593/25F/45/TB are powered by an external +5V regulated power supply.

The Models 593/25F, 593/45, and 593/TB isolates transmit data (XMT+ and XMT-) and receive data (RCV+ and RCV-). The Model 593/45 has a RJ-45 on both sides, the Model 593/TB has a terminal block on both sides, and the Model 593/25F has DB-25 female connectors on both sides.
