Additional functions include a selective automatic or manual monitored restart of the safety function, synchronous time monitoring of 0.5 or 1.5 seconds for all two-channel applications, or the integrated Monoflop function for higher device availability.
The SNO 4083KM safety relays are suitable for conventional safety tasks in mechanical and system engineering, as well as applications in lift engineering (according to EN 81-1), and in controls for industrial combustion plants (according to EN 50156-1).
For increased safety, all of these applications are easily implemented without the user having to press a control button or connect additional configuration terminals. Wieland’s SNO 4083KM relays can be used in safety-oriented applications up to PLe /Category 4 according to EN ISO 13849-1 or SIL 3 according to EN 62061.
