These safety relays and brought to you with a clever design that allows the monitoring of dangerous operations. To initiate a dangerous movement both operators must be activated within an interval of 0.5 seconds which is referred to as synchronous activation. If one of the two pushbuttons are released during a dangerous operation, the control sequence is automatically cancelled. Users can resume the dangerous operation through both pushbuttons returning to their initial position and reactivating them within the required time interval. The XPSUS range of safety modules have been created and designed to monitor:
