PL e - SIL 3 safety speed monitoring interface
Safety speed monitoring interfaces. Safety level up to PL e - SIL 3
SV MR0 - Safety speed monitoring relay for Overspeed and Zero speed control
SV MR0 U - Safety speed monitoring relay for Underspeed control
Both modules integrate:
Guided-contact safety relay
Selectable manual orAutomatic restart
EDM feedback input for external contactors monitoring
Enable inputs used, for instance, when monitoring the same axis, in different working phases, with more modules configured with different thresholds
Faults are signalled by LED Fault and a PNP system status output. PNP status output indicating overspeed or underspeed thresholds crossing
SV MR0 and SV MR0 U integrates:
2 inputs for PNP proximities switches
3 front panel selectors allow configuration of the speed threshold
