Industrial Ethernet
Modbus TCP is a communication protocol for industrial automation technology based on Ethernet. Modbus TCP corresponds to the direct implementation of the established Modbus protocol (RTU) to a TCP/IP based communication. Existing Modbus applications can thereby easily use a connection-based, secure exchange of process data via an existing Ethernet network.
Contrary to other protocols, Modbus can handle delayed messages which occur often e.g. for modem connections or wireless networks.
This way, Modbus enables reliable control, device monitoring and data recording, even from a distance.
AUMA actuators with AC .2 actuator controls support Modbus TCP, allowing easy and flexible integration into virtually any type of network.

The wall bracket (WH) and the cable set for wall bracket (LSW) allow mounting the actuator controls separately from the actuator.
Retrofitting is always possible and is particularly appropriate if actuators are difficult to access, subject to strong vibration or high ambient temperatures at valve level, for example.
The maximum permissible distance is 100 metres.

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.

Part-turn actuators
With the FQM fail safe unit, AUMA offers innovative and safe actuator solutions for automatic operation of valves in case of emergencies making use of stored mechanical energy.
Constant torque characteristics across the overall torque range.
The spring is not operated during standard operation. As a consequence, actuator sizing can be relatively small.
The end position switches are automatically set during the setting procedure of end positions OPEN and CLOSED and do not require separate adjustment.

AM (without display)
AM actuator controls with their straightforward design are the perfect choice when using parallel signal transmission while a relatively low number of feedback signals is required. Few parameters need to be defined via sliding switches during commissioning, e.g. type of seating in end positions. Control is made via operation commands OPEN, STOP, CLOSE. Reaching an end position and collective fault signals are reported back to the DCS as feedback signals. These signals are visually displayed at the local controls via the indication lights. As an option, the valve position can be transmitted as 0/4 – 20 mA signal to the DCS.
