32 Channel RS485 Temperature Acquisition Paperless Recorder Modbus RTU Board 10K B3950 NTC Sensor Resistance Measurement (8CH with DIN Case)

NT48A08 NT48B20 NT48C32 is an 8-32 channel Modbus RTU NTC temperature collector developed and produced by eletechsup. In addition to collecting temperature, it can also be used as a multi-channel non-powered resistance value measurement for any component.Features:Standard MODBUS RTU protocolDC 7-25V wide voltage power supplyMultiple baud rates and check bits can be setTemperature measurement range: -20 ° C to +125 ° CMeasuring temperature and resistance at the same timeUp to 32 channels of temperature can be tested simultaneouslyDescription: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 code4: The default baud rate is 9600BPS, the baud rate can be selected by command 2400 4800 19200 38400 57600 115200BPS5 You can choose the parity mode is no parity, even parity and odd parity6:Adapted sensor:10K B3950 1% NTC thermistor, Up to 8/20/32 NTC sensors can be connected at the same time7:Temperature measurement range (using our NTC sensor): -20 ° C to +125 ° C.8:Temperature measurement accuracy (using our NTC sensor): 1%.9 Only Board Size: 8CH 72*55*15MM,20CH 99*72*15MM,156*72*15MM10 With DIN Case Size: 8CH 87*57*34MM,20CH 102*87*34MM,159*87*34MM11 Only Board Weight: 8CH 23g,20CH 38g,32CH 56g12 With DIN Case Weight:8CH 73g,20CH 114g,32CH 171gNT48A08 NT48B20 NT48C32 can be used to measure temperature with NTC, and it can also be used to measure common resistance value.

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.
