The Pepperl+Fuchs FieldConnex system provides a top to bottom (host to device) range of fieldbus solutions for hazardous and non-hazardous installations. The heart of this system is a field barrier, which provides a means of connecting intrinsically safe instrumentation to a bus that has an EEx e trunk. The field barrier can be located in a Zone 1 gas group IIC hazardous area, and comes optionally as a DIN rail mounted version that allows it to fit in with any installation’s requirement. Pepperl+Fuchs also introduced a fieldbus power conditioner (with an MTBF of better than 5000 years) that provides 1A to a fieldbus trunk from dual redundant power supplies. This approach optimises bus availability and avoids the complexity, heat dissipation and low efficiency of other methods. The FieldConnex system also includes power supplies, repeaters, spur protectors, junction boxes, cables, bus couplers, field mounted valve interfaces and bus terminators.
