fety ba> Wide product range for all standard applications of theautomation
> Flexible and space-saving – available in single and double channel versions
> Time-saving installation thanks to simultaneous– snap-on mounting on rails
and – connection to PE and earth
> Reduced stock-keeping thanks to a uniform back-up fuse
The R. STAHL INTRINSPAK safety barriers of Series 9002 can be used for various tasks in the field of automation. The wide product range and scope of different combinations offer you a large field of applications.The safety barriers allow the intrinsically safe operation of HART transmitters, proximity sensors, potential-free contacts, temperature sensors, DMS, solenoid valves, indicators and others.Due to the compact width, space-saving and flexible installation in the switch cabinet is possible. Thanks to DIN-rail mounting and simultaneous connection of the equipotential bonding, theinstallation can be performed very easily.
