RS232 Converters
Overview
The RS232 Converters family are opto-isolated and not isolated RS232 to RS422/485 converters with an automatic send-receive change over (Auto RTS / Auto Toggling), for a large field of application. The CS-428i and CS-428/9AT ISO converters are opto isolated converters. CS-428i supports AC (85 - 235VAC, 50 - 60Hz) or DC (10 - 30VDC) power supply methods. CS-428i is designed for wall mount and is provided with a DIN Rail Adapter for easy installation. The RS232 converters CS-428/9AT PRO and -mini operates without an external power supply (but optional you may use an adapter if required). The CS-428/AT mini is one of the smallest RS232 converter in the world.
