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 aluminium and featuresprotection degree IP20.The junction box is equipped with a selectablebus terminating resistor. The accordingswitch is integrated in the housing onthe board.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.Accessories: To increase the degree ofprotection, there are various aluminium andstainless steel housings with IP6x rating andvarious cable glands available on request.● Entity and FISCO compliant accordingto IEC TS 60079-27● Junction box for DIN rail mounting● Aluminium housing● 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)● Switch-in terminating resistor● Cable shielding: Capacitive or directconnection with housing potentialselectable via switch94 /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
