Safety relay PL d / SILcl 2

Safety relay 46311.B2

can optionally be expanded with 16 sensors via input expansion for N.O./N.O. combination


Safety relay 46311.B2 is space-saving thanks to the compact and slim 463 design.



Product characteristics:

  • SIL 2 / PL d
  • 2 sensor inputs
  • 1 potentially free relay safety output
  • For sensors with N.O./N.O. combination
  • Installation and maintenance time is reduced as guard door and emergency stop monitoring are combined in one device.
  • LED display for simple diagnosis
  • Up to 16 sensors can be connected via elobau input expansions


Up to 16 sensors can be connected via an interconnection system. With the sensors, we recommend using our 363 V99 / 363.97 interfaces
