I have the 1769 I/O modules listed below but I have lookec in the manuals for each model and can't seem to find what I need to size a breaker for each one.

I have 1769-IA16, 1769-OA16, 1769-IQ16, 1769-OB16.

They each go to an IFM module but I wanted a breaker to protect each module and I also have to find fuse sizes for the fusible IFM's for the 2 output modules.

I assume .5 amp per point will be good for for the output fuses but how do I size a breaker for the load of each module? I see nothing that gives me that info.
