The Ex ec field device coupler series 9410 for Zone 2 are used for reaction-free connection of up to 12 FOUNDATION Fieldbus H1 or PROFIBUS PA field devices to the high-power trunk. The spurs with ec or ic type of protection can be used for fieldbus devices in Zones 2 (ic, ec) and 1 (d, q, m) and are short-circuit limited.The integrated power management minimises start-up and short-circuit currents.
- For connection of 4, 8 or 12 fieldbus devices in Zone 2
- Ex ec or ic spurs
- Operation on the high-power trunk
- Reduced start-up current thanks to power management and short-circuit limiting with disconnection
