Description
The GE IS230TAISH2C TMR DIN Rail Analog I/O Module is engineered for high-integrity analog signal acquisition and output in Mark VIe safety control systems. It consists of the IS220YAICS1A I/O pack and a DIN-rail mounted analog terminal board, supporting Triple Modular Redundancy (TMR) and Simplex configurations. In TMR mode, the controller selects the median input value to reject outliers, while a patented output circuit ensures faulty I/O packs are excluded from signal generation.
