powering BCS with 5Vdc

[cbenn22]

I know the BCS controllers are supposed to be powered with 6Vdc-10Vdc... I purchased a 120VAC to 5Vdc transformer to power a relay module and was wondering if anybody had success powering their BCS with only 5V?

Wrong. The BCS runs on 120v, and then converts it to a 5vdc signal for the outputs. You need 120v to power the BCS... If you want to run your devices without your BCS, then your 5vdc converter will be perfect to act as that auxiliary for your SSR switching the BCS normally operates.

Do you own a bcs? Obviously not!

The BCS uses a standard wall wart transformer. It comes with a 6vdc 1 amp transformer. I measure 4.2vdc on the outputs with a 6vdc input. So a 5vdc input might drop the output voltage even more. My relays have a low end control voltage of 4vdc so I am right at the threshhold. Still works fine though.

There is definitely loss within the bcs. I have a 462 fwiw.
