Actuator controls, Simple actuator controls with basic functions

AM

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.

Simple actuator controls with basic functions

Design features

  • Modular interface concept for remote control
  • Local controls with lockable selector switch, push buttons and indication lights
  • Programmable control logic (”push-to-run operation” or “self-retaining”)
  • Programmable type of seating (limit or torque seating)
  • Separate mounting onto wall bracket possible
  • Motor control via reversing contactors or thyristors (option)
  • Phase monitoring with automatic phase correction
  • External 24 VDC supply (option)

Service conditions

  • Wide temperature range
  • Highest enclosure protection
  • High quality corrosion protection

Interface and functional properties

  • Control inputs for different voltages (DC/AC)
  • Potential-free output contacts for status signalling
  • Fieldbus interface
  • Functional safety:
    In selected configurations, safe end position feedback up to SIL 2 is possible

Interfaces

  • Electrical connection via AUMA plug/socket connector (terminals as an option)
  • Cable entries in different versions
