Tom,
Thanks for the info. We had the 24B modules with the 48VDC setting voltage.

Take a look at document B0193AC- IA Series System Equipment Installation
(Under Version 6 documents) FBM24/25 field connections if you have
access to the CSC website. It looks like there are three versions:
24A is a voltage monitor
24B is a contact sense with internally supplied 48VDC wetting voltage
24C is contact sense with externally supplied wetting voltage
I suspect these are 3 different modules and not just different TCAs, so
you are probably stuck with whatever you have. We do not use any of
these modules so I cannot say for sure.

Foxboro Gurus,
Can an FBM 24 provide wetting voltage for contact sensing without using
an
external power supply? If so what is the wetting voltage. The PSS
sheet is a
little unclear, at least to me.
Thanks,
Cyrus Taft
