Odd Q: Can two controllers share one water temp and one fan RPM wire?

[ZeroOne]

The short version of this is: can two controllers share the same fan's RPM wire, and/or temp probe? Will this cause any electrical issue?

Long version: Have a Lamptron FC10 display. Not a huge fan of the controller portion but love the nixie tubes. Wanting to team this up with an Aquaero 5 LT to automate thing with the Lamptron just displaying temps and RPM. It would be nice to be able to just splice the RPM wire to make it go to two controllers, assuming it's just a pulse that is read. Might not be so simple for the water temp sensor though.

Worst case, can use one fan from each radiator for each controller, and use a 2nd water temp sensor.

Yes for the rpm wire, I do it all the time in testing. It is just pulses being fed out.

Not sure but guessing no on the temp probe, thought many analog probes are resistance based so splitting would screw that up.

Thanks for the reply... Rpm was the most important. Can have a second temp easily enough.
