Let's talk relays

I used the original housings and ‘filled’ it with electronics.
For the horn and other stuff a single PROFET will do the job.

Smart relay in LUCAS housing

Hi Jagies, I was thinking of a “smart” relay to drive my cooling fans and started designing such to fit in the original Lucas relay housings. The idea was to PWM control the fans and to run them for a while after the engine was shut down. In my prototype design an external (DSB18B20) and internal temperature sensor (NTC) is available and it could also be used to control lights of course. ! Does such device already exist, is anyone of you interested or have you got more ideas ? Best Regards, T…
