Safety Controllers
ABB offers safety relays for all kinds of safety devices. Their safety relays have great flexibility and a wide range of input options. The relays are small and compact with an excellent reliability and safety level.
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.
