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.
