R.STAHL safety barriers INTRINSPAK series 9004 are used for
various applications.
Because of the electronic current limitation these barriers are
suitable for the intrinsic safe power supply of field devices.
The barriers of the series 9004 offering a smaller series resistance
and therefore more power on the intrinsic safe side compared to
the safety barrier series 9001 and 9002.
A broad range of versions are available for electrical circuits with
negative or positive potential.
The types 9004/5... with electronic voltage limitation enabling the
application of unregulated power supplies.
