NT48A08 NT48B20 NT48C32 is the new version of RS485 NTC temperature collector from eletechsup. It has 8/20/32 channel versions to choose from. It can simultaneously measure the temperature of up to 32 channels or the resistance value of conventional resistors.
Features:
Standard MODBUS RTU protocol
DC 7-25V wide voltage power supply
Multiple baud rates and check bits can be set
Temperature measurement range: -20 ° C to +125 ° C
Measuring temperature and resistance at the same time
Up to 32 channels of temperature can be tested simultaneously
Description:
1: Operating Voltage : DC 7-25V(DC 9V 12V 15V 24V)
2: Operating Current :10-30MA(depending on the number of external NTCs)
3: MODBUS RTU Command support 03 04 06 16 function code
4: The default baud rate is 9600BPS, the baud rate can be selected by command 2400 4800 19200 38400 57600 115200BPS
5 You can choose the parity mode is no parity, even parity and odd parity
6:Adapted sensor:10K B3950 1% NTC thermistor, Up to 8/20/32 NTC sensors can be connected at the same time

NTC sensor specifications:
Product Name: 5*25mm NTC Waterproof Probe
Total length : 50CM
Resistance value: 10K
Resistance accuracy: ±1%
Resistance B value: 3950 ± 1%
Temperature range: -20 ° C -125 ° C
Wire size: 2651 26# parallel line temperature 105 °C
Plug model: XH2.54-2P
Note:
This module does not have an NTC sensor. The NTC sensor needs to be purchased separately (10K B3950 1%);The module's measured resistance value is 1%, and the theoretical temperature range is -273s~200°C. The final temperature measurement accuracy and temperature range are determined by NTC thermistor.
