What is the Difference Between Electrical and Mechanical Relay Life? Hardware: Switches>>General-Purpose>>PXI-2570
Problem: In the specifications for our electromechanical relay switch modules, the Expected Relay Life is described in terms of Mechanical and Electrical. What is the difference between these two different specifications? Solution: Mechanical Relay Life: This is the number of operations which a relay can be expected to perform while maintaining mechanical integrity. Mechanical life is normally tested with no load or voltage applied to the power contacts. Electrical Relay Life: The minimum number of cycles the relay will make, carry, and break the specified load without contact sticking or welding, and without exceeding the electrical specifications of the device.
