Select car relay time parameters

- Nov 03, 2017-

The following parameters should be taken into consideration when selecting the time parameters of the relay: Aging time Release time Ammonia back-off time Release back-off time Relay time parameters are defined as follows:

The typical waveform on the oscilloscope during the time test

① normally open contact

② normally closed contact

③ break contacts after contact O b s Note: action time back-off time bridging time

④ first contact after the break contact r t c release time conversion time of stable closing time

1) When using a car relay, it is generally not concerned with the time parameter.

2) Pay attention to the combined car relay time, such as flash frequency.
