Over/Under Protection

The CB100L/900L provide you the over/under temperature protection for your equipment or products in process. When the temperature goes above or below the set value (high limit or low limit), the CB100L/900L will interrupt or remove the power from the process. This output can be used for alarm or interrupting power to the heater circuit.  For safety reason, the output will be retained until reset operation is executed even when the measured value goes back to the normal range. Reset operation can be executed by front key operation, communication, or digital input.
The CB100L/900L limit actions can also be configured :
  • Limit output at power-up : ON/OFF
  • Alarm output : Energized/de-energized
  • Limit type : High-limit for over-temperature / Low-limit for under-temperature
  • The CB100L/900L measures the time while the measured value goes above/below the set value, and it retains the peak value.
