Safety relay 470121H1.

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


Safety relay 470121H1. is space-saving thanks to the compact and slim 470 design.



Product characteristics:

  • SIL 3 / PL e
  • 2 sensor inputs
  • 2 potentially free relay safety outputs
  • For sensors with N.O./N.C. combination
  • Slim, space-saving design
  • Easy installation with plug-in, screwless terminals
  • Up to 16 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)


Up to 16 sensors can be connected via an interconnection system. With the sensors, we recommend using our interfaces 363 098.
