solenoid breakout - 2 allowed???

FIRST General Forum

Dear Chief Delphi community,

we are having hard time to understand if we are allowed to use two solenoid breakouts on one Crio Controller.
Does anyone knows if we are allowed to use two solenoid breakouts on our Controller??

Thanks!

You’re allowed 2 solenoid breakouts, but each has to go into it’s own module. On the 4 slot, they’ll go into 3 and 4.

In software, the first one (in slot 3) will be module 1 and the second one (in slot 4) will be module 2. You’ll use:

public Solenoid(int moduleNumber, int channel)

instead of

public Solenoid(int channel)

to instantiate Solenoid objects.

Also note, only one solenoid breakout board can run at 24v. If you need a second one, it must be wired to 12v.

Has anyone discovered a reason that the second breakout card could not be powered by a 12 to 24 converter sourced from a segregated circuit breaker on the PDB? R54 seems to prohibit this, but I would like another opinion.
