CTI designs and manufactures advanced control, communications and I/O products for process control. The 2500 ™ Series® PLC system is a compatible replacement for the former Simatic ™ 505 PLC system, and includes state-of-the-art enhancements in functionality and performance. Products in the family include controllers, power supplies, bases, remote base controllers, analog and digital I/O, Ethernet TCP/IP, Modbus, DeviceNet networking modules and specialty I/O modules.
CTI 2500 ™Series® products are installed in the plants of major industrial companies throughout the world. They are continuing a heavy development investment in this system, with plans for enhancements in the instruction set, programming tools, network connectivity, and I/O system. A micro-PLC family based on the same technology, and a line of compatible networked I/O are included in our long-term product road-map. Control Technology Inc.
2500 ™ Series® Programmable Controller - Compact I/O System The 2500 Series ™ Compact I/O System is designed for use in a broad range of applications, including those that require discrete and analog control. It is compatible with the 2500 Series ™ System, but offers a much smaller form factor. Components include the Base, Power Supply, Remote Base Controller (allows connection to any Profibus Master) and I/O modules.
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.
