9411/11 series Ex e field device couplers for Zone 1 can be used for interference-free connection of eight 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 minimises start-up and short-circuit currents.
Available with screw terminals or spring clamp terminals.
- For connecting eight fieldbus devices in Zone 1
- Operated using High Power Trunk concept
- Reduced start-up current thanks to power management and short-circuit limiting with disconnection
