How to get the relay time parameter

How to get the relay time parameter

Answer:

The literature refers to a relay time parameter computer detection method, which uses self-developed acquisition board, which is mainly composed of single-chip and its peripheral circuit
Therefore, when the contact circuit is connected to the AC circuit, the contact instantaneous value between the contacts to determine the size of the contact closed and off the state, the error will be great, so no accurate value.
However, in this way, when the relay is connected to the DC load, the instantaneous value of the single-chip port voltage may be small or close to zero when the AC voltage is alternating due to the alternating current load.
