Function: KFD2-STC5-Ex1

Esta barrera con aislamiento se utiliza para aplicaciones de seguridad intrínseca.

El dispositivo alimenta a transmisores SMART de 2 y 3 hilos, y también se puede utilizar con fuentes de corriente SMART de 2 hilos.

Transfiere la señal analógica de entrada a la zona segura como un valor de corriente aislada.

Las señales digitales pueden superponerse en la señal de entrada en el área peligrosa o no peligrosa, y se transfieren de forma bidireccional.

El dispositivo proporciona salida en modo de disipador o en modo de alimentación en los terminales de la zona segura.

El dispositivo cuenta con una resistencia interna. Utilice esta resistencia si la resistencia de comunicación HART del circuito de control es demasiado baja.

Los terminales del dispositivo integran casquillos de prueba para la conexión de comunicadores HART.
