News: DC 12V 24V 8-32CH RS485 NTC Temperature Collector PLC Analog Acquisition Board Resistance Meter Passive Switch On/Off Detection NT48C32

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

7:Temperature measurement range (using our NTC sensor): -20 ° C to +125 ° C.

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

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.
