CTI 2500-IADP I/O Adapter for Series 500

2500-IADP I/O Adapter for Series 500

The 2500-IADP is an I/O Adapter that enables the use of CTI 2500 Series® I/O modules within legacy Texas Instruments Series 500 I/O bases.

This adapter offers a seamless upgrade path, allowing you to modernize your Series 500 system without a complete system replacement. You can immediately replace failed Series 500 I/O modules with reliable CTI 2500 Series® modules.

When budget and/or time permits, you can then transition to a full CTI 2500 Series® system without losing your initial investment in the replaced I/O modules.

Product Bulletin

The 2500-IADP is an I/O Adapter which allows

the use of CTI 2500 Series I/O modules in Texas

Instruments Series 500 I/O bases. It provides a

transparent path for upgrading old Series 500

systems without the requirement to completely

replace the system.

Failed 500 Series I/O modules can be replaced

by plugging CTI 2500 Series™modules into the

2500-IADP. Then, when your budget allows, you

can plan a complete upgrade of your 500

system with CTI 2500 Series™- without losing

your investment in the replaced I/O modules!

2500-IADP I/O Adapter for Series 500

Using the 2500-IADP

The 2500-IADP provides electrical and me- chanical adaptation of a CTI 2500 Series I/O module to the Series 500 I/O

slot. However, because the Series 500 system employed field wiring that was terminated at the I/O base, conversion

using the 2500-IADP will often involve re-routing of the I/O wiring to the front of the new module.

Here are the basic steps involved:

1. Compare the Series 500 module you plan to replace with the new CTI 2500 series module. As an aid in select

ing a replace- ment, the chart on page 2 shows CTI replacements for the most commonly used Series 500 I/O

modules.

A. Do they have the same number of points / channels? If not, you may need to make addressing changes

in your program.

B. Do the new modules use the same PLC login? Are overflow / underflow and other error and status bits

reported in the same manner? For alog modules, are the inputs scaled to the same range? If not, you

will need to make addressing and logic changes in your program.

C. How does the field wiring for the new module differ from the old one?

2. Develop a re-wiring plan for replacement of your old module. There are two basic approaches:

A. Run jumper wires from the I/O termina- tions on your Series 500 base up to the I/O connector for the new

CTI 2500 Series module.

B. Remove the I/O terminations on the Series 500 base and run new wires from your panel termination up

to the new CTI 2500 Series module.

3. Implement your re-wiring plan and verify that your rewiring has been completed accurately.

4. Make any necessary changes to the I/O

5. Install the 2500-IADP and your new CTI 2500 Series module.
