The number ofslaves can be extended by the EEx efieldbus supply which can be loopedthrough from multibarrier to multibarrier.Inputs and outputs of the trunk line featureincreased safety protection (EEx e) and theoutputs to the field devices are intrinsicallysafe (EEx i).The multibarrier is equipped with an selectablebus terminating resistor. This switch isintegrated in the housing on the board.The multibarrier is equipped with four LEDslocated on the printed circuit board insidethe housing to provide short-circuit indicationsseparately for each channel.Because of complete galvanic isolation ofthe● trunk line to EEx i outputs and betweenthe● EEx i outputs,safe operation is guaranteed.● Entity and FISCO compliant accordingto IEC TS 60079-27● Galvanic isolation between the EEx ioutputs and the EEx e bus line, aswell as between the EEx i outputs● Powder-coated die-cast aluminiumhousing● Pressure compensation element forprotection against condensationwater● Connection of the housing potentialvia an M5 x 1 bolt● Temperature range: -20…+70 °C(-4…+158 °F)● Integrated terminating resistor(switch-in)● Cable shielding: capacitive connectionto housing potential● Output data: 10 V/40 mA (short-circuitproof)34 /0309 Hans Turck GmbH & Co.KG • Witzlebenstraße 7 • 45472 Mülheim/Ruhr • Germany • Tel. +49 (0)208 4952-0 • Fax +49 (0)208 4952-264 • more@turck.com • www.turck.com
