Canal doble Z787.H
La solución para aplicaciones con transmisores de 3 cables consiste en una combinación de una barrera de 28 V, 300 Ω y 28 V con un retorno del diodo. Debería concederse una consideración especial a la caída de tensión interna debido al retorno del diodo. Aplicación típica: transmisión 4-20 mA.
Isolation Barriers
Pepperl+Fuchs shunt zener diode barriers are for use as safety interfaces between intrinsically safe and non-intrinsically safe circuits. They are manufactured from Makrolon® and designed to conduct electrical signals - in either direction - between safe and hazardous areas and to limit the amount of energy which can be transferred from a safe to a hazardous area in the event of fault conditions occurring in the safe area. All systems shown are licensed for [EEx ia] IIC Class 1, Div1, Groups A-G.
