The SIPLUS S7-1200 SM 1231 RTD 8AI (model number: 6AG1231-5PF32-2XB0) is an analog input module manufactured by Siemens, designed for the SIMATIC S7-1200 series of programmable logic controllers (PLCs). This module is built upon the base model 6ES7231-5PF32-0XB0 and is protected with a conformal coating for reliable operation in extreme environmental conditions. It can operate stably within a very wide temperature range of -40°C to +70°C (start-up temperature from -25°C). This module provides 8 analog input channels for resistance temperature detectors (RTD), enabling precise temperature measurement in industrial automation systems. The module has a net weight of 0.289 kg and packaging dimensions of 9.00 x 11.00 x 8.50 cm.\n
