Linear actuators
Electric linear actuators performing a linear movement for automating globe valves, for example, can be combinations of SA multi-turn actuators and LE linear thrust units. If a lever arrangement has to be operated, the LE linear trust unit can also be mounted onto a base.

Multi-turn gearboxes
GP multi-turn gearboxes in combination with SA multi-turn actuators act as multi-turn actuators with higher output torques.
They are typically used with stem gate and wedge gate valves. Due to their compact design, these gearboxes can also be used in confined spaces.

Multi-turn gearboxes
If the drive shaft is to be positioned at a certain angle to the output drive shaft, combinations of the SA multi-turn actuators with GST spur gearboxes are used.
The output torque can be considerably multiplied.

Part-turn gearboxes
In spite of the high degrees of automation, there are still valves requiring manual operation. This is in particular the case if the respective valves are only rarely operated for opening or closing.
The GHE type range with the housing made of bronze is suitable for operating part-turn valves (butterfly valves and ball valves), as predominantly deployed in shipbuilding.

Industrial Ethernet
HART makes use of the known 4 – 20 mA standard signal for analogue data transmission. HART communication is modulated as additional signal to the analogue signal. Advantages: The digital HART signal can be transmitted simultaneously to the digital signal. The existing 4 – 20 mA infrastructure is thus also available for digital communication. Consequently, this allows for reading additional parameters and diagnostic data from field devices.
HART is based on the host-field device principle. The optional multidrop HART topology essentially complies with the line structures of fieldbus systems. In most cases, the conventional 4 – 20 mA point-to-point communication is used.

Communication systems
Many different fieldbus systems are available on the market. Certain preferences have evolved on a regional level or specifically to certain plant applications. Since AUMA actuators are implemented in all types of technical process plants around the globe, they are available with interfaces for the different established fieldbus systems within the process automation industry.
Overall, AUMA devices are available with digital and analogue inputs to connect additional sensors to the fieldbus.

AC (with display)
AC actuator controls are your perfect solution if the application requires self-adapting control functions, data logging, a configurable interface or if valve and actuator are to be integrated into a Plant Asset Management System due to advanced diagnostic functions.
AC actuator controls are equipped with a parallel interface for free configuration and/or interfaces to fieldbus systems as used within process automation.
The diagnostic functions comprise a time-stamped event report, torque characteristics logging, continuous recording of temperatures and vibration within the actuator and, furthermore, counting the number of starts and motor running times.
Further to the basic functions, AC actuator controls offer a number of options to meet special demands. These include torque bypass to unseat valves if tightly seated or functions for extending operating times to avoid water hammer within pipelines.
With the development of the AC 01.2, particular emphasis was laid on user-friendliness and the ease of integration of actuators into the DCS. The large graphic display is used to perform menu-controlled programming of the actuator controls, optionally using AUMA CDT via wireless Bluetooth connection. For fieldbus connections, AC programming can be performed from the control room.

AC (with display)
AUMA offers sophisticated control for premium safety requirements with AC 01.2-SIL or ACExC 01.2-SIL actuators controls. SA .2 and SQ .2 actuators combined with these actuator controls can be deployed in safety-related system systems up to SIL 3. AC 01.2 actuator controls in SIL version are equipped with an additional SIL module designed for the execution of safety functions. In case of an emergency at the plant and when requesting a safety function, the standard logic of AC is bypassed and the safety function is performed via the safe SIL module. Consequently, the safety function always overrules standard operation. SA .2 and SQ .2 actuators equipped with these actuator controls have been certified by TÜV Nord. They are suitable for the following safety functions:
