The 2500 Series® Programmable Controller System is designed for use in a broad range of applications, including those that require discrete and analog control. 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.

The 2500 Series® Compact Programmable Controller System is designed for use in a broad range of applications, including those that require discrete and analog control. It is compatible the the 2500 Series® System, but offers a much smaller form factor.

The 2500 Series® Slice I/O System is designed for use in a broad range of applications, including those that require discrete and analog control. It is compatible the the 2500 Series® System, and offers modularity down to a single module, without the need for an I/O base and RBC. Slice I/O modules operate from 24VDC power and communicate with a remote 2500 Series® CPU using Ethernet to read/write directly to the PLC memory or I/O image table. This allows transparent integration into the 2500 Series® system without the requirement for any complicated configuration step. Ethernet connection to the CPU can be accomplished using the on-board port on 2500-Cxxx Processors, or using a 2572 / 2572-A Ethernet module. Note that when using 2572 or 2572-A modules, Slice I/O can be connected even to legacy Siemens® and Texas Instruments PLCs.

Several models of Slice I/O are available with different mixes of I/O and with additional communications options including RS232/485 and 900MHz radio. Slice I/O modules feature Universal Analog Inputs which allow connection of 0-5V, 0-20mA, thermocouple, and RTD sensors. All Slice I/O modules can also be configured to communicate over Ethernet using Modbus-TCP.
