EX9000/EX9000-Modbus Series
EX9510/A                                                                                                                  Isolated RS-422/485 Repeater

Key Specifications/Special Features:

The EX-9510/A repeater boosts the RS-422(EX9510A)/485 signals to extend the reach distance up to 4000 ft (1200m) and increase the maximum number of connected nodes up to 128.

With a special circuitry, EX-9510/A is able to automatically detect the data flow and switch the direction of the data lines accordingly.

“Auto baud rate detector” enables EX-9510/A to automatically configure RS-422(EX9510A)/485 signals to any baud rate without external switch setting.

Build in Opto-isolations on EX-9510/A provides 3000VDC of isolation to protect the host computer from ground loops and destructive voltage spikes on the RS-422(EX9510A)/485 data lines.

EX-9510 also offers internal surge-protection on the data lines. Internal high-speed transient suppressors on each data line protect the module from dangerous voltages levels or spikes.
