The easySafety control relay for safety-related applications monitors all commonly used safety devices and also takes over the required control tasks for the machine. Packed with a host of conventional safety relays in the form of safety function blocks, easySafety not only features integrated safety functions but also standard functions in a single device—all in one. In addition to the safety circuit diagram containing the safety configuration, the safety control relay also contains a standard circuit diagram. This circuit diagram can be used for standard tasks, such as the processing of diagnostics signals or general control tasks of a machine.

Application Description

Because of the large number of safety function blocks, the user can tackle a large number of application options with only one device. The user can also respond directly to future and changing application requirements. This saves financial resources and offers future investment security. Last but not least, it reduces the stock-keeping required for special safety relays. The easySafety meets the requirements of Category 4 to EN 954?1, PL e to EN ISO 13849?1, SILCL 3 to EN IEC 62061 and SIL 3 to EN IEC 61508. With easySafety, it is possible to implement applications meeting the most stringent safety requirements.

Safety function blocks:

  • Emergency stop
  • Guard door monitoring with and without interlock/guard locking
  • Two-hand control (EN 574)
  • Electro-sensitive protective devices (light curtains)
  • Light curtain muting
  • Enable switch
  • Start device
  • Operating mode selector
  • Safety timing relay
  • Overspeed monitoring
  • Feedback loop monitoring (EDM)
  • Zero speed monitoring
