Módulo de expansão de E/S digitais Eaton easyE4 AC, 16 entradas, 4 saídas de relé, 100-240 V AC (197222)

Industrial automation engineers and panel builders use the Eaton easyE4 AC expansion module to add digital I/O capacity to an easyE4 control relay. It mounts on a 35 mm DIN rail and connects to the base unit via the easyE4 expansion bus, providing 16 AC digital inputs and 4 relay outputs for switching loads up to 8 A. The module operates from a 100-240 V AC supply and is suited for machine control, building automation, and small-scale process applications.
