The max. current limitationis selected for all ports via a rotaryswitch. The following values can be selected:30, 35, 45 and 60 mA.The housing is made of robust die-cast aluminiumand features protection degreeIP67.The junction box is equipped with a selectablebus terminating resistor. The accordingswitch is integrated in the housing onthe board.To avoid condensation build-up in the housing,the devices are equipped with a condensatedrain.The shield is capacitively coupled to thehousing potential. A switch for direct couplingof the shield and housing is implemented.Attention: Sufficient equipotential bondingof the installation must be ensured. The deviceis connected via the bolt of the housingto the system’s potentializer.● Entity and FNICO compliant accordingto IEC TS 60079-27● Mounting possible in zone 2● Junction box for wall mounting withPVC cable glands M20 x 1.5● Powder-coated die-cast aluminiumhousing● Pressure compensation element forprotection against condensationwater● Connection of the housing potentialvia an M5 x 1 bolt● Short-circuit protection per dropline/spur● For Ex applications: -25…+70 °C(-13…+158 °F); for non-Ex applications:-40…+70 °C (-40…+158 °F)● Integrated terminating resistor(switch-in)● Cable shielding: capacitive or directconnection to housing potential selectablevia switch● Isolated support terminal for optionalprotective conductor incorporatedin cable42 /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
