8CH Temperature & Resistance Acquisition Board Modbus RTU RS485 NTC Thermocouple Sensors Paperless Paperless Recorder Controller (Only Board+8X 5M NTC)

NT57B08 is a low-cost and cost-effective 8-channel NTC collector designed and produced by eletechsup. It can not only use NTC to measure temperature values, but also directly measure resistance values of 1K-200K ohms. It can be used in IoT, farms and industrial control occasions.​​ 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 8 channels of temperature can be tested simultaneously ​​Description:​1: Operating Voltage : DC 7-25V(DC 9V 12V 15V 24V)​2: Operating Current :10-16MA(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 Parity : NONE/EVEN/ODD​6:Adapted sensor:10K B3950 1% NTC thermistor, Up to 8CH NTC sensors can be connected at the same time​7:Temperature measurement range (using our NTC sensor): -20 ° C to +125 ° C.​8:Temperature measurement accuracy (using our NTC sensor): 1%.​9:NT57B08 can not only use NTC to measure temperature, but also measure resistance values of 1K-200K ohms.​10:Size : 59*50*14(Only Board) ,65*55*26(With DIN Case)​11:Weight: 27g (Only Board) ,52g(With DIN Case)​​NT57B08 can be used to measure temperature with NTC, and it can also be used to measure common resistance value.
