Siemens SIPLUS S7-300 SM 331 Analog Input Module

The Siemens SIPLUS S7-300 SM 331 (6AG1331-1KF02-7AB0) is an analog input module based on the 6ES7331-1KF02-0AB0. It features conformal coating for enhanced protection in harsh environments and operates in a temperature range of -25°C to +70°C. This module provides 8 isolated analog inputs with a resolution of 13 bits, supporting voltage, current, resistance, and various temperature sensor types (Pt100, Ni100, Ni1000, etc.). The conversion time is 66 ms, and it uses a 1x 40-pole connector.

This module is designed for demanding industrial applications where precise analog signal acquisition is critical, such as in process control, chemical plants, or outdoor installations. The conformal coating makes it suitable for environments with high humidity, corrosive substances, or significant temperature fluctuations, ensuring reliable operation of S7-300 automation systems.
