WAGO-I/O-SYSTEM 750 Process Image 87750-464 2/4 AI RTD configurableManualVersion 1.0.17.4.4 Pt1000 (acc. IEC 751)With the setting "Pt1000 (acc. IEC 751)" and activated Siemens format, the I/Omodule converts the resistance measured values of Pt1000 sensors (acc. IEC 751)and outputs them as temperature values.The temperature values are displayed at a resolution of 1 digit per 0.5 °C.The status information is depicted in bit 0 to bit 2 and the digitalized measuredvalue in bit 3 to bit 15.Table 73: Process image for 750-464, Pt1000 setting (acc.
