Finder's new 70 series modular
rail-mounted monitoring relays provide the solution to the increasing health
and safety demands and the need to protect valuable equipment. It offers the
maximum flexibility in 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 distribution 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. With a
selectable fault memory (lock-out), safety is increased by preventing
uncontrolled restarting of equipment.
With a wide range of adjustments to
maximise application flexibility, the monitoring relays features two or three
colour LED indicators for immediate visual indication of supply status. The
functions and values are programmable from the front face, simplifying set-up
and adjustment.
Within the 70 series range are units
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 offer:
- Voltage limits between 170 - 270 for single phase supplies
- Voltage limits between 300 - 480 for three-phase supplies
- Switch off delay time between 0.5 - 60 seconds
- Variation of phase asymmetry between 4% - 25%
- Modules available in 17mm or 35mm - dependant on the type
