The WJ225 series products can be applied in RS-485 bus industrial automation control systems, temperature signal measurement, monitoring, and control, etc. The product includes power isolation, signal isolation, linearization, A/D conversion, and RS-485 serial communication. Each serial port can connect up to 255 W1J25 series modules, and the communication method adopts ASCII code communication protocol or MODBUS RTU communication protocol. The address and baud rate can be set by code, and can be hung on the same RS-485 bus with control modules from other manufacturers for easy computer The WJ225 series products are intelligent monitoring and control systems based on microcontrollers. All user set calibration values, addresses, baud rates, data formats, parity checks, and other configuration information are stored in non-volatile memory EEPROM. The WJ225 series products are designed and manufactured according to industrial standards, with isolation between signal inputs/outputs, capable of withstanding 1000VDC isolation voltage, strong anti-interference ability, and high reliability. The working temperature range is-45 ℃ to+85 ℃ programming. WJ225 General Parameters: (Typical @+25 ℃, Vs is 24VDC) Input type: Pt100 input/Pt1000 input Measurement temperature range:-200~600 ℃ Accuracy: 0.1% Temperature drift: ± 50 ppm/℃ (± 100 ppm/℃, maximum) Bandwidth:-3 dB 10 Hz Conversion 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. (Channel conversion rate=AD conversion rate/number of open channels) Note: Please recalibrate the module after modifying the conversion rate, otherwise the measured data may have deviations. You can also specify the conversion rate when placing an order, and we will recalibrate the product according to the conversion rate you require when it leaves the factory. Common moderejection (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 protection Communication: Protocol RS-485/RS-232 standard character protocol and MODBUS RTU communication protocol Baud rates (2400, 4800, 9600, 19200, 38400, 57600, 115200bps) can be selected by software The address (0-255) can be selected by software Communication response time: 100 ms maximum Working power supply:+8~32VDC wide power supply range, with internal anti reverse and overvoltage protection circuits Power consumption: less than 1W Working 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 1mA The RS-485 output and power supply are grounded together.
