The invention relates to a field bus arrangement with a field bus distributor (11) for mounting in the area (1) at risk of explosion, for feeding a plurality of field devices (121 to 12n), arranged in the area (1) at risk of explosion, via intrinsically safe electric circuits (13) from at least one

The invention relates to a field bus arrangement with a field bus distributor (11) for mounting in the area (1) at risk of explosion, for feeding a plurality of field devices (121 to 12n), arranged in the area (1) at risk of explosion, via intrinsically safe electric circuits (13) from at least one high-energy voltage source (21) arranged in the area (2) not at risk of explosion. For this purpose, in the area (2) not at risk of explosion, a field bus coupler (22) arranged in the area (2) not at risk of an explosion and having three electric circuits which are DC-isolated from one another is provided.
