ELECTRIC ACTUATORS enhancing IIoT APPLICATIONS A


s the Industrial Internet of Things (IIoT) gains momentum, the enhanced internetworking of


physical devices is yielding cyber-physical systems with improved process state


visualisation, higher-level modelling and simulation capabilities, and improved process control. AUMA’s electric valve actuators play a key role in these systems: on the one hand, they make remote process operation possible by opening and closing valves. On the other hand, intelligent electronics allow the actuators to act as information hubs for both process-related and actuator- related data, based on advanced self-diagnostics.


Electric actuators from AUMA provide enhanced connectivity for IIoT applications


As an application example, several hundred AUMA actuators have been successfully integrated into a real-time sewer network control system for the city of Vienna, Austria. After heavy rain, the scheme has cut  more than 50% and so reduces water pollution. Online rainfall


forecasting and real-time simulation help to optimise capacity management of holdup reservoirs spread across the 220km2 Vienna’s catchment area.

The actuators provide essential valve position feedback to the system. Following the results of the real-time simulation model, the actuators are centrally controlled  Although any kind of communication scheme can be used to embed actuators into such systems, including 4–20mA  advanced industrial ethernet interfaces for  suitable and provide unprecedented connectivity.
