RTU, Ethernet/IP networks, Profinet and Profibus.

Thejunctionboxiseitherinapolycarbonateorastainlesssteelhousing. Thereisalsoapackage for DIN rail mounting (without field housing) for mounting in user’s own control cabinet.

The IP67/Nema 4 protective housings of the fieldbus junction boxes are designed for wall mounting. They also withstand harsh industrial environments and prevent dust, water and moisture reaching the electrical connections.

Note: The converter can only send data. E.g. it is not possible to change the parameters through the converter.

Important: This product shall not be used contrary to these user instructions provided by the manufacturer, or safe use of the product may be compromised.
