PROFIBUS-PABasicsThis situation can be remedied by a topology which is based on the use of mainline (trunk line) featuring “enhanced safety”and intrinsically safe outputs.This is where the multibarrier is employed,permitting a current of up to 10 A in thetrunk line area, and when connected inseries, supplying up to intrinsically safe32 stations in the explosion-hazardousarea.PCPROFIBUS-DP RS485DP/PACouplerPTB 00 ATEX 0000 X PTB 00 ATEX 0000 X PTB 00 ATEX 0000 X PTB 00 ATEX 0000 X PTB 00 ATEX 0000 X PTB 00 ATEX 0000 X PTB 00 ATEX 0000 X PTB 00 ATEX 0000 X PTB 00 ATEX 0000 X PTB 00 ATEX 0000 X PTB 00 ATEX 0000 X PTB 00 ATEX 0000 X PTB 00 ATEX 0000 X PTB 00 ATEX 0000 X PTB 00 ATEX 0000 X PTB 00 ATEX 0000 X PTB 00 ATEX 0000 X PTB 00 ATEX 0000 Xexcom Segment outPROFIBUS-PAFig. 4 shows the typical configuration ofa PROFIBUS-PA network with TURCKmultibarriers.

PROFIBUS-PAMultibarrier MBD48-T415/Ex –Basics and application benefitsThe operating principle of the MBD48T415/Ex multibarrier is physically basedon IEC 61158-2. The use of multibarriersincreases the number of fieldbus stationsin the PROFIBUS-PA network to a maximum of 32 field devices.This high number of stations is achievedby enhanced safety of the fieldbus supplywhich can be looped through from multibarrier to multibarrier. The fieldbus stationsin zone 0 are supplied with power viathe four intrinsically safe outputs of eachmultibarrier device.User benefitsThe user can expect substantial cost advantages due to the possibility of cascading the multibarriers in a single segmentin the explosion hazardous area, thus fullyexploiting the entire function range of thebus systems.All fieldbus devices can be operated ina single fieldbus segment in the explosion hazard area. Thus, the costs for anadditional bus coupler or a segment cardas well as their integration and parameterdefinition are eliminated. An additionaltrunk line and the wiring material is alsospared.The supply of power to the multibarriersis implemented via the bus which meansthat an additional power cable is notrequired.Installation in the explosion hazardous areaThe area of application to ATEX isII 2 (1 GD) G EEx m e [ia] IIC T4.Due to its EEx e protection rating, theMBD48-T415/Ex multibarrier can beinstalled in zone 1 (II 2 G) according to94/9/EC (ATEX 95a).Use in explosion hazardous areas withexplosion protection group IIC – in conjunction with temperature class T4 – is thestandard in the process industry.Within zone 1, the MBD48-T415/Ex isconnected via a cable and connectionswith enhanced safety (EEx e) to the mainline (trunk line) of a fieldbus conform toIEC 61158-2. This offers the advantagethat the connection to the bus can beimplemented using a loop isolator withoutEX approval, but with a sufficiently highcapacity.Intrinsic safety and galvanic isolationbetween all outputsFor safety reasons, galvanic isolation ofsignals plays a decisive role in the Ex area.The multibarrier provides four intrinsicallysafe and galvanically isolated outputs. Thecomplete galvanic isolation exists betweenthe main bus cable (trunk line) and the output circuits as well as between all of thefour individual output circuits.Galvanic isolation of intrinsically safe circuits, as demanded by the industry,particularly for zone 0, is thus provided.Potential transfers and potential equalization currents are thus reduced and safedata transmission is guaranteed.Operational safetyOperational safety of the bus system mustbe guaranteed should a bus station failor malfunction. The four outputs of themultibarrier each supply an output currentof max. 40 mA.If a short-circuit occurs on a fieldbus station, the integrated short-circuit protectioncomes into play. Only the affected outputwill be shut down, the main line and theother outputs of the fieldbus segmentremain operational. The short-circuit isindicated for each channel by a red LEDinside the housing.Industrially suitable housingIndustrial environmental conditions are frequently harsh and aggressive. Therefore,a housing suitable for these conditions isnecessary. The enhanced IP66 degree ofprotection and the special housing material (die-cast aluminium) – in conjunctionwith the encapsulated module electronics– meet these demands and provide a highlevel of operational safety. Direct installation of a multibarrier in the system is thusunproblematic.The EEx e cable glands guarantee safeand quick connection technology inconjunction with the high-quality cageclamps.Functions which supplement thestandard FISCO conformityThe FISCO model has been developedfor the supply of power to fieldbusstations in the Ex area by the PTB incooperation with renownedmanufacturers. FISCO stands forFieldbus Intrinsically Safe Concept.It is intended to simplify the verificationof intrinsic safety of fieldbus systems.Intrinsically safe networks can beconfigured without highly complexcalculations, and also expanded andoperated without system certification.The outputs of the multibarrier conformto the demands of an Ex current supplyand also conform to FISCO. Switch-in terminating resistorsData transmission on bus cables isfrequently influenced by signal reflection,which can occur when the bus ends arenot terminated. The fieldbus must beprovided with a terminating resistor atboth ends in order to avoid signalreflection. The multibarrier is providedwith an integrated terminating resistor,which should be activated, when themultibarrier is connected as the lastdevice on the main bus line (trunk line). Climatic compensationIn regions subject to large temperatureand air-humidity variations, it is possiblethat formation of condensation or abuild-up of water within the housing ispossible during operation. In order toavoid this, the multibarrier is fitted onthe cable connection end with apressure equalisation element to avoidthe build-up of condensation.The pressure equalisation elementfeatures IP67 degree of protection andguarantees continuous and reliableventilation and venting of themultibarriers. The ePTFE diaphragm inthe centre of the gland features a veryhigh water ingress pressure and repelsoil. Even 100 % of salt crystals are keptout.Shield terminals are capacitively connected to the housing potential in order todivert possible interference voltages onthe cable shield. The riveted ground boltconnects the housing to the main potential equalisation.Hans Turck GmbH & Co.KG D–45466 Mülheim/Ruhr Tel. 0208/4952-0 Fax 0208/4952-264 E-Mail: more@turck.com Internet: www.turck.com11 /04072
