505 Modernization & Replacement
Your legacy Siemens/TI 505® or SIMATIC® 505 system doesn't have to be a liability.
The CTI 2500 Series® is a compatible, drop-in replacement: controllers, I/O and communications that fit your existing racks, wiring and programs, so you modernize incrementally instead of ripping everything out.
Keep the investment you've made in equipment, engineering and training while gaining modern speed, memory and connectivity for a fraction of the cost and risk.

CTI 2500® JANUS IEC-61131-3 – PAC
The 2500 Series®has its roots in the “ahead-of-its-time” Texas Instruments/Simatic 505®Series system known for its robust performance, intuitive design, and elegantly simple PID and special function programming.
The 2500 Series®reinvigorates and modernizes this legendary product line with more memory, more speed and many new features while maintaining backwards compatibility. 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.

The new “JANUS” Processor brings completely new capabilities to the CTI 2500 Series® System. Designed to work seamlessly with existing 2500 Series® and Simatic®/TI 505 Systems as well as to look to the future with state-of-the-art programming, protocols and capabilities, including direct access to the Industrial Internet of Things (IIoT) using MQTT.
This Programmable Automation Controller (PAC) is fast, agile and optimized for quick, easy, and cost-effective communications. It features integrated drivers to an industry-leading number of protocols, allowing communications with best-in-class I/O devices, drives, and HMI/SCADA no matter the manufacturer. Programmed with CTI’s user-friendly and budget-friendly new JANUS Workbench Software, which supports all IEC-61131-3 programming languages. Initially available in our Classic size, a fully-featured Compact version will be available .
Product List
CTI 2500® CLASSIC
The 2500 Series® Classic Programmable Controller System is designed for use in a broad range of applications, including those that require discrete and analog control. The system is designed to be a compatible replacement for Texas Instruments and Siemens 505® systems. Components include the CPU and the support devices that provide operator interface, communication, I/O control, and power.

These systems perform the same functions as relays, static control, or card logic control systems. They can detect the change in state of input signals from such devices as pushbuttons, limit switches, and analog sensors. Acting on this information and executing a relay ladder logic (RLL) program stored in memory, the CPU produces output signals to drive motor starters, solenoids, pilot lights, modulating control valves, etc.
These signals are used to regulate the operation of various pieces of equipment. A full line of discrete, analog, word, and intelligent I/O modules are available for handling almost any input or output specification. These I/O modules are rugged, plug-in devices capable of functioning within operating specifications in harsh environments.
