For voltage signals it handles -1 V to +1 V, -5 V to +5 V, and 1 V to 5 V ranges; current inputs cover 0 to 20 mA. Resistance and direct voltage/current measurement modes are also available, giving flexibility for a range of transmitters and sensors. The module carries CE mark, UL approval under File E239877, and KC approval, covering European, North American, and South Korean regulatory markets. The EN 50155 certification is the key differentiator — it confirms the module meets the railway application standard for temperature, shock, vibration, and power supply variations.","metaTitle":"Siemens 6AG1331-7KF02-2AB0 Analog Input Module, -40 to 70°C","metaDescription":"Siemens 6AG1331-7KF02-2AB0 analog input module.
