Tachometer input voltages (Read 154 times)

I am installing an electronic ignition module from Rotec. I have not been able to get a response from them to my quesitons. The ICU that they use appears to be similar to a BOSCH unit with a hall sensor trigger. It has a tach output, but no indication if this is sending the hall triggering voltage as a pulse or something higher.  If you have dealt with this type of ICU tacho output in the past can you tell me if it connects to the high voltage or low voltage EMS input. Right now, I have it connected to the high voltage input. Thanks for any help you can render.

Can someone please help me with this question? I am at a loss and need to hook this up.  Don't want to get it wrong and burn out my EMS or not register any RPM. Thanks.

This is a forum for Dynon Engine Monitoring Systems.
Nothing to do with Rotec Electronic Ignition.

Maybe here?

I know this is a Dynon forum. I am installing a Dynon EMS and Skyview system. The EMS has tachometer inputs for either high or low voltage. I am asking here to see of others have connected a similar electronic ignitiion with tach output to a Dynon system. I am hoping that there is some shared experience. Have you installed an electronic ignition with a tach output to your dynon system? If so, any help would be appreciated.

I haven't dealt with a hall type sensor but I have a P-Mag (electronic ignition) that sends voltage directly to the Dynon EMS. The P-Mag documentation provides the output information necessary to determine the correct input to the Dynon EMS.

You will likely need to contact the MFG of the sensor to know which input to use since no one else here seems to have used the same setup.

Thanks Ray. I actually came here second after not getting any response from the Rotec forum. I keep trying there but crickets. I guess I will have to spend the dime to call Australia, but I was trying to avoid that.
