………………………………………………………………… ENGLISH ………………………………………………………………… Thank you for choosing Delta DVP series PLC. DVP08NTC-S is able to receive 8 points of RTDs, such as RTD, NTC Series and PTC(NXP-KTY81) sensors, and convert them into 16-bit digital signals. Through FROM/TO instructions in DVP Slim series MPU program, the data can be read and written.

Note2: DVP08NTC-S only supports 2-wire RTD sensor, which has no mechanism to compensate. Note3: If there is noise, please connect the shielded cables to the system earth point, and then ground the system earth point or connect it to the distribution box.

Example: Use Pt1000(H00) to set CH1, NTC 30K(H06) for CH2; and the setting value would be H0600 written into CR#1. Use Self-defined temperature/resistance table 8(H19) and disable channel for CH6 (HFF); the setting value would be HEF19 written into CR#3. ...

Self-defined Temperature/Resistance Table A total of 8 templates are provided with DVP08NTC-S. When there’s no built-in sensors inside the module, you can use the sensor after inputting values into the template provided by the manufacturer. In addition, self-defined temperature/resistance table is also possible. You can only use “NTC wizard”...

Introduction to NTC and Sensitivity The NTC sensitivity about temperature changes also represents resistance’s rate of changes, which can be seen from the slope of the line in the chart below. The greater the slope the higher the sensitivity; therefore, the sensitivity of line A would be higher than line B as a result of a greater slope.

NTC敏感度常数介绍 敏感度常数表示热敏电阻对温度变化的敏感度(代表电阻的变化率) ,变化率可以由直线的斜率表示,斜率 越大灵敏度越大,如下图所示直线 A 斜率大于直线 B 斜率,这代表着直线 A 敏感度大于直线 B 敏感度。 Low Sensitivity High Sensitivity Temperature (T) 敏感度常数的方程式可由两个温度之间的电阻变化率决定,其方程式如下所示。 ln − ln Sensitivity = − 2.3026(log − log − Sensitivity () = ...
