Siemens 6ES7231-5PF32-0XB0 Input Module 6ES72315PF320XB0

SIMATIC S7-1200, Analog input, SM 1231 RTD, 8xAI RTD module

The SM 1231 RTD analog signal module measures the value of resistance connected to the module inputs. This value can be either temperature or resistance.
● If resistance, the nominal range full scale value will be decimal 27648.
● If temperature, the value will be reported in degrees multiplied by ten (for example, 25.3 degrees will be reported as
decimal 253).
The SM 1231 RTD module supports measurements with 2 wire, 3 wire and 4 wire connections to the sensor resistor.
