Connections made safer with I/O box
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, the Type 8643 meets all explosion-protection requirements, as well as offering users maximum 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 use in these sectors, the device is available either in an aluminium or polyester casing with IP65 protection, or as an electronic module with IP20/IP30 protection for installation in Ex-e enclosures or control cabinets. In addition, the 8643 has reliable galvanic isolation between its power supply, bus port and inputs and outputs, making it safe and easy to install.
