PDFRepetidor PSM-ME-RS485/RS485-P
Repetidor RS485 a RS485
- Amplifique las señales RS485 hasta 1,2 km
- Agregue 32 nodos a un circuito de datos RS-485
- Velocidades de transmisión de hasta 1,5 Mbps
- Aislamiento tridireccional entre todas las interfaces
Potencie, o amplifique, las señales RS-485 para cubrir mayores distancias con el repetidor PSM-ME-RS485. Los repetidores RS-485 utilizan líneas de tensión diferencial para las señales de datos y control a fin de subsanar las limitaciones de los puertos de serie estándar. Esto le permite añadir 1,2 km y 32 nodos a un circuito de datos RS-485. Además, el aislamiento tridireccional protege los dispositivos frente a sobretensiones transitorias y bucles de tierra en la línea de datos.
El repetidor PSM-ME-RS485 se desarrolló para las grandes exigencias de los sistemas de bus de campo. El dispositivo se puede montar en pared con suministro eléctrico de CA o instalados en carriles DIN estándar y con un suministro de 24 V CC o CA.
El repetidor PSM-ME-RS485 se puede utilizar en todos los sistemas de bus de 2 hilos comunes: Modbus, RACKBUS (Endress & Hauser), SUBCONET-K (Moeller), UNI-TELWAY (Telemecanique), DANBUS (Danfoss), RS-BUS (Landis & Staefa), NET 2000 (B&R), INSUM (ABB), J-BUS (Merlin Gerin), ET-WAY (Jetter), S-BUS (SAIA) y alrededor de 60 sistemas de bus de empresas específicas más.
El repetidor PSM-ME-RS485 es la solución óptima para una separación potencial y un amento del alcance en sistemas de bus de 2 hilos RS-485.
