The 2500-RADP is an RBC Adapter that enables the use of CTI 2500 Series® RBCs and Processors, including CTI’s new Janus line of processors, within legacy Texas Instruments Series 500 I/O bases. This adapter offers a seamless upgrade path, allowing you to modernize your Series 500 system without a complete system replacement. You can immediately replace failed Series 500 RBCs and Processors with reliable CTI 2500 Series® equivalents. When budget and/or time permits, you can transition to a full CTI 2500 Series® system without losing your initial investment in the replaced modules.
