PEPPERL+FUCHS 2108HAT is a high-performance isolated safety barrier launched by Pepperl+Fuchs,designed for industrial control systems.It is mainly used to isolate hazardous areas from safe areas to ensure electrical safety and comply with international safety standards.The following is a comprehensive analysis of its core functions and technical features:
I.Product positioning and functions
Isolation and protection
As a safety barrier,2108HAT isolates the signals in hazardous areas(such as explosive gas environments)from those in safe areas through electrical isolation technology to prevent safety accidents caused by overvoltage,overcurrent or electric sparks.
Signal transmission and processing
It supports bidirectional transmission of analog or digital signals,and is compatible with the signal input/output of a variety of industrial sensors(such as pressure and temperature sensors)and actuators.It also has signal conditioning functions(such as filtering,amplification,and linearization).
Safety certification
It complies with international safety standards(such as IECEx,ATEX),is suitable for hazardous areas such as Zone 0/1/2,and meets explosion-proof requirements.
2.Technical parameters and performance
Isolation level
-Electrical isolation voltage:≥500V DC
-Isolation resistance:≥100MΩ
-Isolation capacitance:≤10pF.
Signal transmission range
-Analog input:4-20mA,0-10V and other standard signals
-Digital input:compatible with TTL/RS-485 and other protocols.
Environmental adaptability
-Operating temperature range:-40℃to+85℃
-Protection level:IP20(need to be used with cabinet).
3.Application scenarios
Industrial automation
-Hazardous area sensor signal acquisition(such as chemical plant pressure monitoring,oil well temperature detection).
-Safety interlock system(such as emergency shutdown circuit).
Energy and power
-In substation automation system,isolate high-voltage control circuits from low-voltage monitoring equipment.
-Gas turbine control system signal isolation.
Rail transit
-In the train signal system,the onboard equipment is isolated from the ground control signal to prevent electromagnetic interference.
