Monitoring Relays from Finder

Finder’s new 70 series modular-rail mounted monitoring relays provide a solution to increasing health and safety demands and the need to protect valuable equipment. The 70 series offers maximum flexibility when monitoring a range of electrical supply parameters in compact easy to adjust units.

Finder’s new relays are ideal 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.

The positive safety logic feature ensures that any failure mode results in the output relay assuming its de-energised position. With a selectable fault memory (lock-out), safety is increased by preventing the uncontrolled restarting of equipment.

The units are designed to monitor single and 3-phase supplies for under-voltage, over-voltage, voltage within set limits, and for neutral loss, phase loss, phase rotation and asymmetry.

The four monitoring relays in the 70 series range (three of which are multi-functional) offer:

• A selection of voltage limits between 170 – 270 for single phase
• Voltage limits between 300 – 480 for three-phase supplies
• Switch off delay time between 0.5 and 60 seconds,
• 4 – 25% variation of phase asymmetry
• Available in 17mm or 35mm
