The Exec field device coupler series 9410 for Zone2 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 Zones2 (ic, ec) and 1 (d, q, m) and are short-circuit limited. The integrated power management minimises start-up and short-circuit currents.
