9410 series Ex n field device couplers for Zone 2 can be used for interference-free connection of up to 12 FOUNDATION Fieldbus H1 or PROFIBUS PA field devices on the High Power Trunk. The spurs with type of protection nA or ic can be used for fieldbus devices in Zones 2 (ic, nA) and 1 (d, q, m) and are protected by a short-circuit limiting function.
The integrated power management minimises start-up and short-circuit currents.
- For connecting four, eight or 12 fieldbus devices in Zone 2
- Ex nA or ic spurs
- Operated using High Power Trunk concept
- Reduced start-up current thanks to power management and short-circuit limiting with disconnection
