WAGO-I/O-SYSTEM 750 Process Image 79750-464 2/4 AI RTD configurableManualVersion 1.0.17.3.7 Ni1000 (acc. DIN 43760)With the setting "Ni1000 (acc. DIN 43760)", the I/O module converts theresistance measured values of Ni1000 sensors (acc. DIN 43760) and outputs themas temperature values.The temperature values are displayed at a resolution of 1 digit per 0.1 °C in oneword (16-bit). Temperature values below 0 °C are represented in two'scomplement binary. As a result, 0 °C corresponds to the numeric value 0x0000and 100 °C to the numeric value 0x03E8 (dec. 1000).The possible numeric range corresponds to the defined temperature range of-60 °C to +300 °C for Ni1000 sensors (acc. DIN 43760).Table 65: Process image for 750-464, Ni1000 setting (acc. DIN 43760)Temperature°CResistanceΩNumeric value 1) Statusbytehex.LEDerrorAI 1, 2Binary Hex.
