The Schneider Electric TMC4AQ2 is an analogue output cartridge designed to expand the output capabilities of a Modicon M241 PLC (Programmable Logic Controller). It provides two configurable analogue outputs that can be used to control external analog devices such as drives, valves, actuators, or other field equipment requiring 0–10 V or 4–20 mA signals. The module has high resolution (16‑bit) for accurate signal generation and integrates into the modular M241 system via a removable spring terminal block
