Safety relay 462121H..

can optionally be expanded with 32 sensors via input expansion for N.O./N.C. combination.


Safety relay 462121H.. has a space-saving, slim 462 design.



Product characteristics:

  • SIL 3 / PL e
  • 4 sensor inputs
  • 1 potentially free relay safety output
  • For sensors with N.O./N.C. combination
  • Space saving due to low installation height
  • Easy installation with screwless terminals
  • LED and control output for simple diagnosis
  • Up to 32 sensors can be connected via elobau input expansions
  • Optionally without operating time for, e.g., slowly closing guard doors (operating time = simultaneity monitoring of the two sensor contacts)
  • EMD input for guard door monitoring


A maximum of 32 sensors via an interconnection system. With the sensors, we recommend using our interfaces 363 098.
