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, Profinet, Modbus RTU, Modbus TCP, HART, Foundation Fieldbus, Wireless HART)
• 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)
• Bluetooth interface to notebook and Android tablet
