The 2500 Series® Classic Programmable Automation Control System is designed 

for use in a broad range of applications, including those that require both discrete

and analog control.  2500 Series® products can be found worldwide in numerous

industries, including food and beverage, oil and gas, air separation, pulp and paper,

mining and foundry, building products, printing equipment, chemicals, pharmaceuticals,

semiconductor, and wastewater/water treatment. CTI designed the 2500 Series®

with a focus on operational simplicity, ease of use, and compatibility across successive

product generations to deliver unsurpassed reliability and the performance you

need at the lowest total cost.

The most important feature of every product CTI sells is compatibility

— both backward and forward.  We don’t obsolete our products and expect customers

to buy our latest control system.  Instead, our products are conceived to allow customers

to improve systems incrementally — building on previous investments in equipment,

programming and training.  A brand new controller with modern features will work

seamlessly with I/O modules from ten years ago or from ten years hence. 

This allows you to upgrade your control system at your own pace and with

minimal disruption.
