The 2500S family of Slice I/O modules expands the capability of 2500 Series® Systems to include small drops of DIN rail mounted intelligent 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 onboard port on 2500-Cxxx Processors, using a 2572 / 2572-A Ethernet module, or using the 2500P-ECC1 Ethernet Communications Coprocessor.
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.
