The iMATIC is an electric actuator series of EMG (Germany). This article is an in-depth board-and-circuit annotated atlas — two long charts: part 1 covers main-board wiring (10 plugs), the detailed wiring diagram, the front view of the main control board and its chips; part 2 covers the solid-state relay, display board, the combined sensor/travel+torque acquisition unit, the nameplate and the complete unit. Original Chinese annotations are preserved (compiled by "执行器技术"), handy for board and terminal reference during maintenance.
