Working Principle:​ The board communicates with the EX2100e control system through a high-speed serial link daughterboard, aggregating and conditioning field signals before passing them to the controller. The H2 version uses a dual-control arrangement with M1 and M2 control sections, making it suitable for systems requiring redundant control paths.
Application Scenarios:​ Power plants and substations for excitation control systems, industrial automation production lines for real-time data collection, and water treatment facilities for automated management.
Installation Requirements:​ Before replacement, confirm the EX2100e system architecture, M1/M2 controller arrangement, terminal wiring, analog signal ranges, relay assignments, and high-speed serial interface. Photographing terminal positions before removal is recommended.
Usage Notes:​ This is a system-interface board, not simply a generic analog I/O card. Verify the HSSL interface and M1/M2 configuration first when troubleshooting. The associated high-speed serial interface and control architecture must be checked before substitution.
