Type 2 control unit with Muting for Ilion and Ulisse photocells

AU SXM control unit, with integrated Muting functions, for safety photocells Ilion and Ulisse, which can be combined to form a Type 2 safety system. Up to 4 photocells may be connected.

The AU SXM interface works with 2 Muting sensors with contemporary logic and is equipped with:

  • Muting Time-out selectable
  • Integrated Override with 2 operating modes selectable
  • Muting Enable input (enable muting)
  • Status signalling system and all the features necessary for the realization of a Muting protection complies with regulatory requirements up-to-date.

Other integratet functions

  • Guided-contact safey relay
  • Start/Restart interlock
  • EDM Feedback input for extra external contactors monitoring
  • Self test every 5 seconds
