All actuators are manufactured upon orders. Due to the modular design, the customer is able to define the optimum device configuration for the application.

The actuators can be integrated into any conventional DCS. They are available as NORM version, with simple integral controls AM or microcontroller operated AC controls. Actuators with integral controls are ready for operation immediately after connection to the power supply and can be operated via local controls. Depending on the version, commissioning can be performed without tools and without opening the device housing. Commissioning and diagnostics is possible via the AUMA PC ToolSuite, free of charge. Connection between PDA or laptop and the actuator is made on the basis of Bluetooth connection.

Control from the DCS is possible either using the operation commands OPEN-STOP-CLOSE or by defining a position setpoint. Commands or feedback signals are exchanged either via conventional parallel interfaces of via fieldbus interfaces. AUMA devices support the following fieldbus protocols: Profibus (V0, V1 and V2), Modbus RTU, Foundation Fieldbus and DeviceNet.
