The SIPLUS S7-1200 SM 1231 RTD (model number: 6AG1231-5PF32-4XB0) 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 temperature range of -20°C to +60°C. The module features 8 analog input channels, primarily intended for directly receiving and converting signals from RTD (Resistance Temperature Detector) sensors into digital values. This makes it highly suitable for industrial applications requiring high-precision temperature measurement, especially in harsh environments. The module has a net weight of 0.286 kg and packaging dimensions of 8.30 x 10.50 x 8.80 cm.\n
