Safety barriers
Safety barriers are used as separating stages without galvanic isolation between intrinsically safe and non-intrinsically safe circuits. By incorporating a safety barrier, it is possible to install level sensors in potentially explosive areas.
The safety barrier and the level controller must be installed outside the potentially explosive area.

Product variant: Series 9002/13, Safety barrier: Positive potential / Evaluation barrier: Positive potential
Product type: 9002/13-280-093-001
Product description: Two-channel safety barrier
Highlights:
-
Designed for the intrinsically safe operation of a wide range of devices such as HART transmitters, solenoid valves, sensors and potential-free contacts.
-
Compact and space-saving design with easy installation on DIN rail.
-
Time saving during installation by simultaneously snapping onto the rail and connecting to PA (protective conductor).
-
Functional description: The two-channel INTRINSPAK safety barriers of the 9002 series ensure the intrinsically safe operation of almost all field devices. The extensive portfolio and the combination of safety barriers cover a wide range of signals. The devices are highly robust and require very little space. A convenient feature is the uniform back-up fuse for all variants.
Particularly suitable for:
-
Solenoid valves
-
Honking
-
Signal lights
-
I/P converter
-
DMS supply
