[button text=”Download PDF” link=”” style=”default” size=”normal” target=”_blank”]

Safety speed monitoring relay for Overspeed and Zero speed control. Safety level up to PL e – SIL 3.

Conforming to:

– 2006/42/EC “Machinery Directive”
– 2004/108/EC “ Electromagnetic Compatibility (EMC)”
– 2006/95/EC “Low Voltage Directive (LVD)”
– EN ISO 13849-1 “Safety of machinery – Safety-related
parts of control systems – Part 1: General principles
for design”
– IEC/EN 62061 “Safety of machinery – Functional safety of
safety-related electrical, electronic and programmable
electronic control systems”
– IEC 61508 “Functional safety of electrical/electronic/
programmable electronic safety-related systems”

Technical Specifications:

– Manual or Automatic restart selectable.
– EDM feedback input for external contactors monitoring.
– Enable inputs used, for instance, when monitoring the same axis, in different working
phases, with more SV MR0 configured with different thresholds.
– Faults are signalled by LED “Fault” and a PNP system status output.
– PNP status output indicating overspeed thresholds crossing.
– 2 inputs for PNP proximities switches.
– 3 front panel selectors allow configuration of the speed threshold.
When the measured speed raises over the threshold, the relays outputs open.
