Product Spotlight – Vital Safety Relay

A simple way to reach the highest level of safety

When several safety devices should control the same output, it is quite common to connect them in series. But to reach PL e, serial connection is not possible and each device should have its own safety relay. Vital offers the capability to exclusively control smaller machine safety systems that would otherwise have required a programmable controller or multiple safety relays. With the Vital safety controller, up to 30 safety devices can be connected in series to one Vital and still reach PL e.

Main benefits

  • One Vital instead of several safety relays
  • Easy to reach Cat 4
  • Easier troubleshooting
  • Easier connection

Main features

  • Used with specific devices or traditional devices with Tina adpaters
  • Models with one dynamic loop, two dynamic loops and logic, one dynamic loop and one 2 channel loop and logic
  • LED indication for status of the device and the loop
  • Info signal
  • Devices with M12 connectors
