Fieldbus coupler - 4 spurs | 9411/24 series
The Zone 2 Ex i Field Device Coupler Series 9411/24 allow easy integration of up to 4 intrinsically safe FISCO field devices to the high power trunk. It functions by ensuring separation of intrinsically safe devices from the non-intrinsically safe field bus to guarantee short-circuit protection for each spur. It reduces and minimizes starting and low short-circuits current from the trunk through its power management feature. It also comes with a switchable field bus-termination on board and Screw terminals or removable screw terminals (Ex i Spurs). It indicates status and shows the faults on each spur on its LED display.
