DZM  Digital Set Motion Failure Detector

View Datasheet      

  • Detect failure of rotating or reciprocating machines
  • Proximity sensor or switch input
  • 3 Decade digital setting accuracy
  • Wide selection of time ranges, 0.01 sec - 100 hours
  • 48 x 48 mm DIN panel mounting or plug in case  
  • 8 Amp single pole relay output
  • Voltages from 12-35  VDC & 115 and 240 VAC
  • 12VDC output for powering sensors
  • Standard 11 pin plug in base

Mode of Operation:     The DZM controller is designed to monitor rotating machinery and to give an alarm output (relay changing state) when the speed of the machine drops below the set value. When powered up the internal relay energises and the time period starts. An input signal, usually from a proximity sensor, is generated as the machine rotates. If the time interval between pulses exceeds the time set on the ZM3 then the relay will de-energise.

The use of a three decade digital push-push switch enables accurate and repeatable setting of the desired time.

Any  subsequent input pulses will reset the DZM and restart the time period. If the automatic resetting of the DZM is unwanted then a latching version is available that will only be reset by removing the power supply.
