Hello new to the forum here but I think I am in the right place due to my searches
I need some help, I am currently trying to figure out how I can use a solid state relay in an automotive aplication to switch polarity...
I have a data logger hooked up to my vehicle and am trying to log the injecter pulsewidth. However my injectors are fired by ground... as in the injector is fed a 120v constant, and the pcm tells which injector to be fired by the proper ground being activated low....
my problem is that My logger only has an input to read High side inputs..... I can use a Electromagnetic relay but I don't think they will respond quick enough for accurate measurement... in come solid state.. I am trying to record down to 1.5ms aprox, so I need something fast to be up to the task....
But here is my question is this possible? If so how would you guys go about wiring said SSR to accomplish the task of showing a 12v reference being activated by the low side of the injector?
any help would be appreciated.... Thanks
