Z787.H Dual Channel

The solution for applications with 3-wire transmitters is implementing a combination of one 28V, 300Ω and one 28V barrier with diode return. Special consideration should be given to the internal voltage drop due to the diode return.,Typical application - 4-20mA transmit

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
