Definition of Repeat Accuracy

Time Delay Relays


What does “repeat accuracy” mean in the Application Data section of your time delay relays?


Repeat accuracy is the percent variance of time within consecutive timing cycles once a time delay relay is set to the required time delay. For example, our TR-6 Series programmable & TR-5 Series non-programmable units have a repeat accuracy of +0.1%. If you set this unit for a 15 second delay, you will always see a delay between 14.985 and 15.015 seconds each time under normal operating conditions (constant voltage & temperature).

See the article on Linear Dial Settings for a discussion on the linear setting of adjustment potentiometers.
