MicroLogix 1200 RTD/Resistance Input Module 15

Publication 1762-IN014B-EN-P - July 2013

To wire your sensor to the module, follow these steps:

1. At each end of the cable, strip some casing to expose the individual wires.

2. Trim the signal wires to 2-inch lengths. Strip about 3/16 inch (5 mm) of insulation away

to expose the end of the wire.

3. At one end of the cable, twist the drain wire and foil shield together, bend them away

from the cable, and apply shrink wrap. Then earth ground at the preferred location based
on the type of sensor you are using.

4. At the other end of the cable, cut the drain wire and foil shield back to the cable and

apply shrink wrap.

5. Connect the signal wires to the module terminal block and input.

6. Repeat steps 1 through 5 for each channel on the module.
