1.Adaptive Sensor: B3950 10K 1% NTC Thermistor, can connect up to 7 NTC sensors simultaneously.
2.1% Accuracy: The accuracy of the module resistance value is 1%, the theoretical temperature measurement range is -273 ~ 200 ℃, the final temperature measurement accuracy and temperature measurement range is determined by the NTC thermistor.
3. Working current: RTU command supports 03 06 function code, 8 ~ 15 MA working current, 6 ~ 24 V supply voltage.
4. Max 247 modules: Can be used cascading up to 247 modules by changing 485 addresses(if more than 16 modules, please use R485 repeater).
5. PCB Material: NT18B07 module is made of PCB material, no deformation after long time use, long-term stability guaranteed.
