ADAM-4510S Isolated RS-422/RS-485 Repeater Module

Download PDFDownload the ADAM-4510S data sheet.


ADAM-45210S ModuleThe ADAM-4510S repeaters amplify, or boost, existing RS-422 / RS-485 signals to enable them to cover longer distances. They extend the communication distance by 4000 ft (1200 m) or extend the number of connected nodes by 32. In addition they offer the advantages of isolation to avoid ground loops and improve reliability in harsh environments.
