AUMATIC AC

With the AUMATIC controls with micro-controller, AUMA offers the 4^th generation of integral actuator controls. The design concept: A modular system consisting of functions, communication interfaces and equipment elements, enables the ideal combination for every valve automation problem to be found.

Vital information to the operation, e.g. number of starts or running time, is recorded by the integral data logger. Thereby settings can be checked and -  if required - optimised. Extensive diagnostic functions allow quick corrective actions in the event of a fault.

The AUMATIC AC controls can be combined with the  multi-turn actuators SA,  multi-turn actuators SAR,  and the  part-turn actuators SG.

Design features:

• Modular interface concept for remote control
• Local controls with lockable selector switch, push-buttons and indication lights 
• LCD display for status indication and programming support
• Non-intrusive actuator setting and control programming
  (in connection with magnetic limit and torque transmitter MWG)
• Separate mounting on wall bracket possible
• Motor control via reversing contactors or thyristors
• Automatic phase correction
• External 24 VDC supply (option)

Ambient conditions:

• High enclosure protection
• High quality corrosion protection
• Wide ambient temperature ranges

Interfaces and features:

• Control inputs with different voltages (DC/AC)
• Potential-free signal relays for status indication
• Analogue control (0/4-20 mA)
• Programmable stepping mode (for running time extension) 
• Freely definable intermediate positions
• Process controller (PID)
• Fieldbus control (Profibus DP/DPV1, Modbus RTU, Foundation Fieldbus, DeviceNet)
• Fieldbus interface also available as component redundancy
• Behaviour in emergency situations and during loss of communication (programmable)
• Limit and torque as analogue signal
  (in connection with magnetic limit and torque transmitter MWG)
• Logging of operating data
• Bluetooth interface to Laptop or PDA (option

Interfaces:

• Electrical connection via AUMA plug/ socket connector (optionally terminals)
• Cable entries in different versions
• FO connection for fieldbus interfaces
