The 2500S family of Slice I/O modules expands the capability of 2500 Series® Systems to include small drops of I/O connected over Ethernet.  Slice I/O modules communicate to 2500 Series® Processors using CAMP protocol and 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. Note: This unit is designed to work on a battery so +12VDC is operating voltage, not +24VDC. NOTE: THIS PRODUCT IS MATURE AND IS  NO LONGER AVAILABLE.
