TM3DI8A

The Schneider Electric TM3DI8A is an 8-channel, standard 24 V DC digital (discrete) input module belonging to the Modicon TM3 modular I/O system. It acts as a fundamental building block for machine automation, providing a reliable and compact interface to connect switches, sensors (e.g., proximity sensors, photoelectric sensors), pushbuttons, and other 24 V DC field devices to a TM3-compatible programmable logic controller (PLC), such as the Modicon M221, M241, or M251 series.
