Product DescriptionNTC to RS-485, Thermistor Temperature Modbus Data AcquisitionModuleWJ126Product Overview:The WJ126 product implements multi-channel signal acquisition between sensors and hosts to detect temperaturesignals. The WJ126 series products can be applied in RS-485 bus industrial automation control systems, temperaturesignal measurement, monitoring, and control, etc. The product includes power isolation, signal isolation, linearization, A/D conversion, and RS-485 serialcommunication. Each serial port can connect up to 255 WJ126 series modules, and the communication methodadoptsASCII code communication protocol or MODBUS RTU communication protocol. The address and baud rate canbesetby code, and can be hung on the same RS-485 bus with control modules from other manufacturers for easy computerprogramm The WJ126 series products are intelligent monitoring and control systems based on microcontrollers. All user setcalibration values, addresses, baud rates, data formats, checksum statuses, and other configuration informationarestoredin non-volatile memory EEPROM. The WJ126 series products are designed and manufactured according to industrial standards, with isolationbetweensignal inputs/outputs. They can withstand 1000VDC isolation voltage, have strong anti-interference ability, andhighreliability. The working temperature range is -45 ℃ to+85 ℃Product selectionWJ126 - Z - T - 485Input type: NTCTemperaturerange: Tcommunication interfaceT1: -20-100℃ T2: 0-100℃T3: 0-150℃T4: 0-200℃T5: 0-400℃Tu: User defined NTC485: Output as RS-485 interfaceCompany ProfileShenzhen Weijunrui Technology Co., LtdSince: 2011Specialty: The company's main products include analog acquisition modules, signal isolators/conversion modules, and signal transmittersCapacity: Produce 10000 per monthAdvanced Features:Switching to TCP/network/remote IO module, Modbus RTU to TCP, RS232/485 to Ethernet, analog signal (current/voltage/thermistor/frequency/displacement/speed/pulse) isolation transmitter, mV differential signal amplifier, isolation amplifier, micro power DC-DC module power supply, etcFunction Introduction:WJ126 General Parameters:The WJ126 signal isolation acquisition module can be used to measure one temperature signal. 1, Temperature signal input12 bit acquisition accuracy, 1 temperature signal input. All signal input ranges have been calibrated beforetheproduct leaves the factory. During use, users can also easily program and calibrate themselves. 2, Communication ProtocolCommunication interface: 1 standard RS-485 communication interface. Communication Protocol: Supports two protocols, the character protocol defined by the command set andtheMODBUS RTU communication protocol. The module automatically recognizes communicationprotocols and can achieve network communication with various brands of PLCs, RTUs, or computermonitoring systems. Data format: 10 digits. 1 start bit, 8 data bits, and 1 stop bit. The communication address (0-255) and baud rate (2400, 4800, 9600, 19200, 38400, 57600, 115200bps) canbeset;The communication network can reach a maximum distance of 1200 meters and is connectedthroughtwisted pair shielded cables. High anti-interference design of communication interface, ± 15KV ESD protection, communication responsetimeless than 100mS. 3, anti-interferenceChecksums can be set as needed. There is a transient suppression diode inside the module, which caneffectivelysuppress various surge pulses, protect the module, and the internal digital filter can also effectively suppresspowerfrequency interference from the power grid.(Typical @+25 ℃, Vs is 24VDC)Input type: NTC resistor inputAccuracy: 0.1%Temperature drift: ± 50 ppm/℃ (± 100 ppm/℃, maximum)Bandwidth: -3 dB 10 HzConversion rate: 10 Sps (factory default value, users can modify the conversion rate by issuing commands.)You can set the AD conversion rate to 2.5 SPS, 5 SPS, 10 SPS, and 20 SPS by sending commands. (Channelconversion rate=AD conversion rate/number of open channels)Note: Please recalibrate the module after modifying the conversion rate, otherwise the measured data mayhavedeviations. You can also specify the conversion rate when placing an order, and we willrecalibrate the product according to the conversion rate you require when it leaves the factory. Common mode rejection (CMR): 120 dB (1k Ω Source Imbalance @ 50/60 Hz)Normal mode suppression (NMR): 60 dB (1k Ω Source Imbalance @ 50/60 Hz)Input protection: overvoltage protection, overcurrent protectionCommunication: RS-485 standard character protocol and MODBUS RTU communication protocolBaud rates (2400, 4800, 9600, 19200, 38400, 57600, 115200bps) can be selected by softwareThe address (0-255) can be selected by softwareCommunication response time: 100 ms maximumWorking power supply:+8~32VDC wide power supply range, with internal anti reverse and overvoltage protectioncircuitsPower consumption: less than 1WWorking temperature: -45~+80 ℃Working humidity: 10~90% (no condensation)Storage temperature: -45~+80 ℃Storage humidity: 10~95% (no condensation)Isolation withstand voltage: 1KVDC between input/output, 1 minute, leakage current 1mAThe RS-485 output and power supply are grounded together.
