Q6: What does contact hysteresis mean?

 

 

Answer: Hysteresis is also known as “deadband”.

This is the difference between the contact setpoint and the contact reset point.

 

For example, if a contact is configured to trip when the measured input increases above 7.5 volts, and the hysteresis is configured as 2 volts, then the contact will reset when the temperature decreases below 5.5 volts.
