SLC analog input resolution

i've dealt mostly with the PLC5 in the past,

but i'm getting ready to do some work with a SLC. what is the
input resolution of the i/o modules? I remember watching someone
scale an input on one once, and seemed to have a max of 32767.
this is 15 bit, correct?

Depends on which analog module you are using and what range the channel is configured for. There are at least the following modules to choose from:

1. 1746-NI4
2. 1746-NI8
3. 1746-NI16V or I
4. 1746-FIO4V or I
