PSM-ME-RS232/RS485-P Serieller Schnittstellen Konverter
RS232-auf-RS485-Konverter mit galvanischer Trennung
- Wandelt RS232 auf RS422 oder RS485
- Übertragungsraten bis zu 115,2 KBit/s
- Unterstützt Vollduplex und Halbduplex
- Elektrische 3-Wege-Trennung
Der PSM-ME-RS232/RS485-P wandelt bidirektional RS-232-Schnittstellensignale auf RS-485-(2/4-polig) und RS-422-Standard um
Der PSM-ME-RS232/RS485-P unterstützt die ausgeglichene 4-polige Vollduplexkommunikation, oder den 2-poligen Halbduplex, und eignet sich für die meisten Anwendungen, einschließlich industrieller, gewerblicher und allgemeiner Bürocomputergeräte. Übertragungsgeschwindigkeiten von 1,2 Kb/s bis zu 115,2 Kb/s können auf Punkt-zu-Punkt- und Punkt-zu-Multipunkt-Netzwerke angewandt werden.
Nutzen Sie den PSM-ME-RS232/RS485-P in allen allgemeinen Bussystemen mit dem UART/NRZ-Datenformat und einer Zeichenlänge von 10/11 Bits. Diese ist die beste "Plug-and-Play"-Lösung für das Umwandeln von RS-232 (V.24) auf RS-422 (V.11) und RS-485 mit elektrischer Isolation.
