1 Channel Zener Barrier With Analogue Output, 250 V max, 120mA max
- RS Stock No. 793-4278
- Mfr. Part No. Z728.H.F
- Manufacturer Pepperl + Fuchs
P&F Single Channel Zener Diode Barriers
Zener barriers provide cost saving Ex-protection for various applications in process automation systems. The amount of energy transferred to the hazardous location is limited to a safe level incapable of igniting the explosive atmosphere.
Typical application - transmitters, transducers, solenoid valves and relays
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
