Monitoring relays help meet safety guidelines

Finder's new 70 Series of modular rail-mounted monitoring relays offer maximum flexibility in monitoring a range of electrical supply parameters, in compact, easy to adjust units.

Machine safety legislation (IEC/EN/BS60204- 1) requires that portable or semiportable motordriven equipment be prevented from starting up in the wrong direction should the local phases be reversed, and a phase reversal monitoring relay can provide for that.

Finder's new relays are suitable for monitoring supplies to machinery, equipment, and installations where failure or variation outside acceptable limits may result in damage to equipment, danger to personnel, or disruption to critical processes or procedures.

Featuring 'positive safety logic,' the 70 Series will ensure that any failure mode results in the output relay assuming its de-energised position.
