Example Logging and Alarming Schemes
The following are but a few of the unlimited logging and alarming schemes readily implemented with the IntelliLogger IL-Mini™ and HyperWare-II:

  • Sample input frequently but only log when value changes by a user defined amount
  • Alarm/Log only when above/below  a threshold
  • Alarm/Log dependent on another channel(s)  value or state
  • Change sampling rate upon some other channel(s) or calculated value conditions
  • Totalize only when above some level
  • Calculate duty-cycle  on time
  • Calculate  and log values  based on multiple inputs
  • Perform actions based on real date, time calendar
  • Output periodic waveforms
  • And much more

1 Note: To preclude personal harm as well as potential instrument damage, at no time should voltages exceeding 32Vdc ever be applied to any terminals on the IntelliLogger IL-Mini™.

2 Note: For switching of inductive loads (relay coils, solenoids, etc), it is highly recommended that clamping diodes or other suppression devices be installed across the relay output terminals to protect from inductive kick voltages upon load circuit current interruptions.

3 Note: It is highly recommended that the Logic Beach CF-IND-128MB, industrial temperature rated, 0 wait-state, 100% tested Compact Flash card be used with the IntelliLogger product family.
