The TM3AI8G is an 8-channel analog input module in the Modicon TM3 I/O family, handling current (0–20 mA or 4–20 mA) and voltage (0–10 V or ±10 V) with 12-bit resolution, ≥1 MΩ impedance, and 1 ms conversion time per channel. Connection is via a 10-way removable spring terminal block with 3.81 mm pitch, accepting up to 1.5 mm² wire; the module mounts on a DIN rail and occupies 23.6 mm width. Typical current draw is 40 mA from 24 V DC at full load.
