I would like to measure the switching times (activating and deactivating times) of a latching relay that i posses.
I have a DPDT single coil latching relay, and i shorted the two NOs to each other, the two COMs to each other, and the two NCs to each other, so i actually have SPDT relay.
The NO pin is connected to the AC-mains (230V, 50Hz), and the COM pin is connected to the load (Up to 16Arms load).
To my knowledge:
1.
When the relay is OFF, then no current is flowing through the contacts, and therefore the contacts dont affect switching the relay ON.
Activating time depends only on coil, and doesnt depend on loads.
2.
When the relay is ON, current is flowing through the contacts, and they create an alternate magnetic field which creates an induced current through the coil.
The size of the induced current depends on the load.
Deactivating time depends on coil and on load.
My questions are:
1. are these two claims are correct?
2. How can i measure the deactivating time if it is different for different loads?
Thanks!
