I cannot find anything anything in the manual for a load resistor, does this PLC not have any built in? Is it a dipswitch setting?
Load Resistors on a Micrologix 1100 & 1746-IF4?

No. The IF4 has an input impedance of 220K ohms on the voltage terminals, 250 ohms on the current terminals.

ML1100 expansion module or embedded analog input?
If expansion module, is it a 1762-IF4? If so see specs below
voltage 200K ohms
current 275 ohms
Embedded analog on a ML1100 is voltage only at 210K ohms
There is a dip switch on the 1762-IF4 to select the type of input current/voltage.
