            Safety relays with forcibly guided contacts

            Safety relays with forcibly guided contacts

            Energy efficiency and safety for your applications

            In the machine- and plantbuilding sector the safety becomes more and more important. Everywhere, safety modules and also safety control systems are used. Despite the increasing use of semiconductor relays, the electromechanical relays are still an important part. Safety relays, i.e. relays with mechanically forcibly guided contacts per DIN EN 61810-3, are used wherever people, machines and valuable goods must be protected from injury and damage. One such relay comprises at least one NC contact set and one NO contact set and is constructed such that the NC set and the NO set can never be closed at the same time. For example, if a NO contact fails when trying to open, the associated NC contact cannot close when the power supply is switched off.
