14 CompactLogix Isolated Analog Input Module
Publication 1769-IN074C-EN-P - March 2011
You can use the bare wire or a spade lug. The terminals will accept a 6.35 mm (0.25 in.)
spade lug.
3. Tighten the terminal screw, making sure the pressure plate secures the wire.
Recommended torque when tightening terminal screws is 0.68 N•m (6 lb•in).
Wire Size and Terminal Screw Torque
Each terminal accepts one or two wires with the following restrictions.
I/O Memory Mapping
Input Data File
For each input module, slot x, words 0-3 in the input data file contain the analog values of the
inputs.
TIP The terminal screws are non-captive. Therefore, it is possible to use a ring lug
[maximum 1/4 inch o.d. with a 0.139 in. minimum i.d. (M3.5)] with the module.
TIP If you need to remove the finger-safe cover, insert a screwdriver into one of the
square wiring holes and gently pry off the cover. If you wire the terminal block
with the finger-safe cover removed, you will not be able to put the cover back
on the terminal block because the wires will obstruct the cover.
