Abstract: A field device for a process plant, may include a power distributing data switch having an electrical primary connection to consume power at a first power level higher than 10W, and at least two electrical secondary connections for combined data communication and power transfer at a second power level of lower than 10W per secondary connection. The field device may also include a housing to accommodate electrical components safe from dust and/or water, which forms a first housing compartment fitted for pressure proof enclosure of electrical components in an environment with explosive or flammable atmosphere and which accommodates the primary connection. The secondary connections may be arranged outside a pressure proof enclosure and outside the first housing compartment. The device may include a protective bridge to isolate leads out of the first housing compartment to connect the primary connection to the secondary connections.
