78 Process Image WAGO-I/O-SYSTEM 750750-464 2/4 AI RTD configurableManualVersion 1.0.17.3.6 Ni120 (Minco)With the setting "Ni120 (Minco)", the I/O module converts the resistancemeasured values of Ni120 sensors (Minco) and outputs them as temperaturevalues.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-80 °C to +260 °C for Ni120 sensors (Minco).Table 64: Process image for 750-464, Ni120 setting (Minco)Temperature°CResistanceΩNumeric value 1) Statusbytehex.LEDerrorAI 1, 2Binary Hex.
