Description
P16000 Transductor de frecuencia de impulsos | Desacoplamiento sin provocar reacciones SIL 3 de señales de sensores de velocidad/revoluciones
El P16000 registra señales de sensores de velocidad y las transfiere y las convierte en señales estándar analógicas con aislamiento galvánico
- Medición de la frecuencia de impulsos, por ejemplo, de sensores de velocidad/codificadores de velocidad para el registro seguro de la velocidad del tren o su parada con aislamiento galvánico y conversión en una señal estándar
- Rangos de medición 0 ... 500 Hz a 0 ... 20 kHz.
- Gracias a la conversión de la frecuencia de impulsos en una señal estándar se evita el trabajo de contadores de impulsos en el controlador.
- Las señales relacionadas con la seguridad procedentes de circuitos de medición ya existentes pueden duplicarse sin provocar reacciones y se pueden enviar a un subsistema posterior.
- La ausencia de reacciones está concebida de modo funcionalmente seguro y alcanza SIL 3.
- 5 años de garantía
La entrada está diseñada de forma que las señales de los circuitos de medición existentes se pueden "compartir" sin que se interfiera en la señal original. Esta ausencia de reacciones es suficiente para el nivel de integridad SIL 3 según EN 61508.
Así, la señal de un sensor, aunque esté orientada a la seguridad, se puede duplicar y se puede enviar a un segundo controlador sin interferencias.
Al mismo tiempo, el producto es resistente a las duras condiciones ambientales de los vehículos ferroviarios. Las interferencias CEM, las temperaturas ambiente extremas y las cargas por vibraciones y choques no afectan al funcionamiento del dispositivo. A su vez, se respetan las disposiciones de protección contra incendios para vehículos ferroviarios.

- Aplicaciones ferroviarias CEM EN 50121-1, EN 50121-3-2
- Aplicaciones industriales CEM EN 61326-1
- Clase de temperatura TX (-40…+85 °C) EN 50155
- Clase de altitud AX (2000 m o 4000 m sobre el nivel del mar) EN 50155-1, EN 50155-2
- Coordinación de aislamiento para el ferrocarril y la industria EN 50124-1, EN 61010-1
- Seguridad eléctrica y protección contra incendios EE. UU. UL 61010
