Siemens SIPLUS S7-300 SM 331 Analog Input Module (8AI Thermocouple)
Siemens SIPLUS S7-300 SM 331 module with 8 isolated analog inputs for thermocouples.
The Siemens SIPLUS S7-300 SM 331 analog input module (6AG1331-7PF11-4AB0) is based on the 6ES7331-7PF11-0AB0. This version features conformal coating for enhanced protection against environmental factors and operates reliably in temperatures from 0 to 60°C. It offers 8 isolated analog input channels designed for thermocouples (types B, E, J, K, L, N, R, S, T, TXK/TXK (L) according to GOST). The module provides 16-bit resolution with a conversion time of 50 ms per channel, connected via a 1x 40-pole connector.
This module is essential for temperature measurement and process control applications in harsh industrial environments, such as chemical plants, outdoor installations, and areas with high humidity or corrosive substances. It is a critical component for S7-300 PLC systems requiring accurate temperature data acquisition from various thermocouple types.
