9411/11 series Ex e field device couplers for Zone 1 can be used for interference-free connection of four FOUNDATION Fieldbus H1 or PROFIBUS PA field devices on the High Power Trunk.
The spurs with type of protection e can be used for fieldbus devices in Zone 1 (d, q, m) and are protected by a short-circuit limiting function. The integrated power management minimizes start-up and short-circuit currents. Available with screw terminals or spring clamp terminals.
Features
For connecting four fieldbus devices in Zone 1
Operated using High Power Trunk concept
