RS485 repeater with auto enabled data line control. Extended temperature rating for industrial applications.
We designed the 485-RPT auto-enabled 2-wire microprocessor controlled RS485 repeater to provide error free data communications via an RS485 link. The RS485 drivers are enable controlled automatically using an on board microprocessor, providing fast multi-drop capability for a variety of applications using the single pair RS485 differential signals.
Extend the RS485 beyond the 4,000 feet limitation, or whenever there is a need to “boost” the RS485 signal.
