Safety relay 46311.B1

can optionally be expanded with 8 sensors via input expansion for N.O./N.O. combination


Safety relay 46311.B1 is space-saving thanks to the compact and slim 463 design.



Product characteristics:

  • SIL 2 / PL d
  • 1 sensor input
  • 2 potentially free relay safety outputs
  • 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 8 sensors can be connected via an elobau input expansion unit


A maximum of 8 sensors via an interconnection system. With the sensors, we recommend using our 363 V99 / 363.97 interfaces
