Description

WG21 Amplificadores aisladores de alimentación | Entrada 4 ... 20 mA | Fuente de alimentación integrada | Ex | Transmisión de señales HART

Fuente de alimentación para transmisores de 2 hilos de seguridad intrínseca y transmisores SMART

  • Transmisión SMART (opcional): transmisión bidireccional punto a punto de datos digitales según la especificación HART®*.
  • Altas tensiones de alimentación y buenas especificaciones para zonas peligrosas: de aplicación universal
  • Amplia gama de fuentes de alimentación: 2 modelos que cubren todas las tensiones de alimentación de CA
  • Separación protegida conforme a la norma EN 61140
  • Protección del personal de mantenimiento y de los equipos subsiguientes frente a tensiones excesivas
  • Aislamiento de 3 puertos: evita que las tensiones parásitas afecten a las mediciones o dañen los equipos
  • Alta precisión de transmisión: transmisión exacta de los valores medidos
  • A prueba de explosiones según ATEX para un uso fiable en zonas peligrosas
  • Carcasa modular de 22,5 mm: diseño compacto para facilitar la instalación
  • 5 años de garantía

La fuente de alimentación repetidora WG 21 se utiliza para alimentar transmisores de 2 hilos intrínsecamente seguros. Suministra energía al transmisor y transmite las señales de medición a la salida con alta precisión mediante aislamiento de corriente. Además de las señales analógicas, la WG 21 puede transmitir el protocolo de datos del transmisor SMART (HART). Admite la comunicación bidireccional entre dispositivos de campo en todos los puntos de la línea.

Las altas tensiones de alimentación, las buenas clasificaciones para zonas peligrosas y una amplia gama de fuentes de alimentación permiten su uso en todo el mundo. Se pueden utilizar hasta 1400 m de cable sin problemas. Gracias a la nueva tecnología de transmisión por transformador, el WG 21 alcanza una precisión de transmisión extremadamente alta para aplicaciones en zonas peligrosas. El paquete ofrece la máxima seguridad de funcionamiento, estabilidad a largo plazo y resistencia a los daños, y puede utilizarse en condiciones ambientales extremas.
