Product details
Z954 Triple Channel
The above drawing shows a RTD temperature sensor in a 3-wire design that relay the measured temperature through a 4.5V 12Ω triple channel zener barrier. The entire system is quasi-floating. All three channels have an identical end to end resistance.Typical application - RTD temperature measuring devices
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
