Module Critical Temperature

Allen-Bradley · Compact 5000 Digital I/O Modules

Was bedeutet CriticalTemperature ?

This diagnostic indicates that the module is above its critical temperature limit, representing a more severe thermal condition than 'OverTemperature'. This condition can lead to immediate shutdown, module malfunction, and 'Uncertain' data quality, with a high risk of permanent damage. The tag automatically resets to 0 when the condition is removed.

Häufige Ursachen

  • Extreme ambient temperature conditions, significantly exceeding the module's operating limits
  • Complete failure of the enclosure's cooling system (e.g., fans, air conditioning)
  • Prolonged operation under severe overload conditions, leading to rapid heat buildup
