Actuator controls, AM (without display)

AMExC

Explosion-proof devices must be used in plants where potentially explosive atmospheres are likely to occur. These devices are designed so that they will not act as an ignition source. They neither generate ignition sparks, nor hot surface temperatures. Certification is performed in close collaboration with national and international certification bodies. For multi-turn actuators SAEx/SAREx 07.2 – SAEx/SAREx 16.2 and part-turn actuators SQEx/SQREx 05.2 – SQEx/SQREx 14.2, AUMA MATIC AMExC 01.1 actuator controls with integral local controls are available.

Explosion-proof, 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)
