About this item
PL e - SIL 3 safety speed monitoring interfaceSafety speed monitoring interfaces. Safety level up to PL e - SIL 3
SV MR0 - Safety speed monitoring relay for Overspeed and Zero speed controlSV MR0 U - Safety speed monitoring relay for Underspeed controlBoth modules integrate:
Guided-contact safety relaySelectable manual orAutomatic restartEDM feedback input for external contactors monitoringEnable 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 switches3 front panel selectors allow configuration of the speed threshold
