The Schneider Electric TM3DI16 is a 16-channel, 24V DC digital input module from the Modicon TM3 distributed I/O system. This cost-effective module expands the input capacity of compatible Modicon PLCs (such as M221, M241, M251) by connecting discrete field devices like push buttons, sensors, and limit switches. It features sink/source (PNP/NPN) compatibility for wiring flexibility and basic status indication.
