Wieland SNO 4083KM Safety Relay


SNO 4083KM Safety Relay Function - after the supply voltage is applied to terminals A1/A2 and the safety inputs are closed, the enabling current paths (NO contacts) are closed and the signal current path (NC contact) is opened automatically or by pressing the reset button (manual monitored start). When the safety inputs are opened/de-energized the enabling current paths (NO contacts) are opened immediately and the signal current path (NC contact) is closed.

The SNO 4083KM safety relay requires fewer connection cables, irrespective of whether operation with or without cross monitoring is desired. The two channel control of the SNO 4083KM is carried out by either an NC/NC or an NC/NO combination of the safety sensor. In the case of two channel control of the device, a synchronous time is automatically monitored between the two channels. The SafeStart function is used with a manual start, the reset input is automatically monitored for a rising and falling signal edge. The Monoflop function is integrated into the safety relay and prevents device interlocking under all circumstances. Simple diagnosis is possible thanks to an intelligent display system that shows the user the different operating modes of the safety relay in its different applications.
