SECU-BAR 125 is installed outside of the Ex-zone and provides an intrinsi-
cally safe output voltage with i
gnition prevention level “ia” and an output
current with ignition prevention level “ib” for electrical equipment in-
stalled in hazardous, flammable environments like
stalled in hazardous, flammable environments like
Industrial sensors for:
Pressure, temperature, humidity, proximity, length, weight
Limit switch position, transducers for non-electrical parameters ...
Electrical equipment in the chemical, petro-chemical industry, tank
farms:
Level indication, overfill prevention, pressure, temperature
Fuelling stations:
Level control systems, overfill prevention systems
Principle of operation
The input voltage is passed via a fuse to a DC-DC-voltage converter which
stabilises the output voltage. Via two electronic current limiting devices in
series the voltage is fed to the output of the barrier. Additional protective
devices provide a power supply for probes in Ex-zone 0. The output voltage
is limited under all circumstances to maximal 25.2 V and the output current
to 131 mA max.
