Safety relay 470221E1U


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

 

Safety relay 470221E1U is space saving thanks to the compact and slim 462 design.

 

 

Product characteristics:

  • SIL 2 / PL d
  • 2 sensor inputs
  • 2 potentially free relay safety outputs
  • For sensors with N.O. / N.O and N.O. / N.C combination
  • Installation and maintenance time is reduced as guard door and emergency stop monitoring are combined in one device.
  • Slim, space-saving design
  • Easy installation with screwless terminals
  • Up to 8 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 8 sensors and 8 E-stop buttons can be connected via an interconnection system. With the sensors, we recommend using our interfaces 363 098.
