216EA62 is a high‑performance analog input unit for ABB REG216 digital generator‑transformer protection system. It receives AC voltage and current signals from external signal transformers, performs simultaneous multi‑channel sampling and analog‑to‑digital conversion, then transmits digitized measurement data to the main processing board for protection algorithm calculation.
Simultaneous sampling design ensures phase consistency for voltage and current signals, which is critical for differential protection, over‑current protection and other generator protection functions. The module adopts standard plug‑in Eurocard structure for convenient maintenance and on‑site replacement. Front‑panel LED indicators help engineers check operating status and locate module faults quickly.
Commonly used in thermal power and hydropower plant generator and main transformer protection cabinets. Disconnect rack control power before replacement, verify hardware revision compatibility. Suitable for on‑site fault replacement and long‑term spare stocking for existing REG216 systems.
