6ES7331-7PF11-0AB0 Siemens Analog Input SM 331 SIMATIC S7-300 8 AI Thermocouples
The Siemens 6ES7331-7PF11-0AB0 is a high-performance 8-channel analog input module from the SIMATIC S7-300 programmable logic controller (PLC) family, specifically engineered for precise measurement of thermocouples (TCs) and resistance temperature detectors (RTDs) in industrial process automation, power generation, HVAC, and manufacturing environments. With its galvanic isolation, advanced diagnostics, and support for a wide range of temperature sensor types, this module delivers reliable, accurate, and interference-free temperature data—critical for process control, safety interlocks, and energy optimization.
Designed for seamless integration into the S7-300 platform and compatible with STEP 7 (TIA Portal or Classic) engineering software, the 6ES7331-7PF11-0AB0 enables engineers to monitor up to eight independent temperature points in a single module slot, reducing system footprint and wiring complexity while ensuring compliance with international standards such as IEC 61131-2 and EN 60529.
