Technical details

2 Ethernet interfaces enabling simultaneous (switched mode) or separate (dedicated mode) use

• Complex measurement device and module topologies can be implemented when used separately

• Easy-to-use extreme value capture functionality for the most important measured variables, such as conductor currents and voltages

• Integrated web server on base device for customized configuration without needing to use additional software

• Capture, analysis and documen­tation of disturbance variables, e.g. harmonics current
• Event and transient detection with storage in PQDiff and Comtrade
• Comprehensive visu­alization in the event browser

• Secure communication through OPC UA security structures
