Schneider TM3AI8: Modicon TM3 I/O expansion, analog input module, Modicon TM3, 8 inputs, screw, 24V DC.
TM3 modules clip onto the right side of the controller and connect through the bus connector, adding I/O without a separate rack. They are configured in EcoStruxure Machine Expert (Basic for M221).
