It supports nine thermocouple types: J (–200 to 1000°C), K (–200 to 1300°C), R (0 to 1760°C), S (0 to 1760°C), B (300 to 1820°C), T (–200 to 400°C), N (–200 to 1300°C), E (–200 to 800°C), and C (0 to 2315°C). Conversion time for a single channel is 100 ms, plus 100 ms per active channel, plus one controller cycle—sufficient for ramp/soak profiles in glass melting or heat treating. ## Mounting and environmental considerations Mounts on TH35-15 or TH35-7.5 DIN rail per IEC 60715, or on a plate with the fixing kit. Width is 23.6 mm. The removable spring terminal block accepts 1.5 mm² wire, pitch 3.81 mm. Input circuits require twisted shielded pair cable under 30 m. Input impedance is ≥1 MΩ. Conversion time includes the controller cycle, so factor that into the task scan. Rated for horizontal operation from –10 to 55°C, or vertical (derated to 35°C). IP20, pollution degree 2, operates at altitudes up to 2000 m. Vibration resistance on DIN rail: 3.5 mm at 5–8.4 Hz, 3 gn at 8.4–150 Hz. Shock: 15 gn for 11 ms. Power draw is 45 mA at 5 V DC and 35 mA at 24 V DC from the backplane. A green PWR LED indicates module supply is present.","metaTitle":"Schneider TM3TI4DG Analog Input Module, 4-channel Thermocoup","metaDescription":"Schneider Electric Modicon TM3 analog input module, 4 thermocouple inputs, 16-bit resolution, LSB 0.1°C, supports J/K/R/S/B/T/N/E/C types.
