product description:
WJ30 product implements signal acquisition between sensors and hosts to detect analog signals. WJ30 series products can be applied to the RS-232/485 bus industrial automation control system, 4-20mA / 0-5V signal measurement, monitoring adsorbed clause: control, and industrial field signal isolation and long-term transmission, etc.
Products include power isolation, signal isolation, linearization, A / D conversion, and RS-485 serial communication. Each serial port can be connected up to 25 5 WJ30 series modules, communication mode supports modbus RTU communication protocol, minimum address is 01, Baudi 9600, data format: 10 digits, 1 start position, 8 digits, 1 bit Stop bit, no reset. Also supports the ASCII code communication protocol, baud rate coding settings, can be hung on the same RS-485 bus with other manufacturers, available for computer programming.
WJ30 series products are based on a single-chip intelligent monitoring and control system, all user-set calibration values, address, baud rates, data formats, correction, and status, configuration information, etc., are stored in the insertion memory EEPROM.
Working temperature range - 45 ° C ~ +85 ° C. WJ30 series products are isolated from industrial standards, manufacturing, signal input / output, can withstand 3000VDC isolation voltages, strong anti-interference ability, high reliability.
