ATEX-approved
September 1st 2008 Bürkert's new Power I/O Box type
8643 is designed to connect
binary signals to Foundation
Fieldbus H1 or Profibus PA in
process systems – easily, cost
effectively and safely. ATEX
approved for operation in Zones 1
and 21, Type 8643 meets all
explosion-protection requirements,
and offers users flexibility
regarding intrinsically safe actuator
and sensor technology.
The Power I/O Box type 8643
replaces conventional discrete
cabling with a modular multiplexed
system, saving space, cabling
costs, and time during verification
and documentation of safety
procedures. The device is suitable
for use in areas subject to
explosion hazards, such as in
petrochemicals, oil and gas, the
pharmaceutical industry, water
treatment and fine chemistry. For
these sectors, it is available either
in an aluminium or polyester
casing with IP65 protection, or as
an electronic module with IP20/
IP30 protection for Ex-e enclosures
or control cabinets. More articles from Burkert Fluid Control Systems: |
