Product Overview:
The WJ126 product realizes multi-channel signal acquisition between the sensor and the host, which is used to detect temperature signals The WJ126 series products can be applied to RS-485 bus industrial automation control systems, temperature signal measurement, monitoring, and control, etc.
The includes power isolation, signal isolation, linearization, A/D conversion, and RS-485 serial communication. Each serial port can connect up to 255 W126 series modules, and the communication method uses the ASCII code communication protocol or MODBUS RTU communication protocol. The address and baud rate can be set by. It can be connected to other manufacturers' control modules on the same RS-485 bus, which is convenient for computer programming.WJ126 series products are intelligent monitoring and control systems based on microcontrollers, all user-set calibration values, addresses, baud rates, formats, checksums, and status, etc., are stored in non-volatile memory EEPROM. WJ126 series products are designed and manufactured according to standards, with signal input / output isolation, can withstand 1000VDC isolation voltage, strong anti-interference ability, and high reliability. Operating temperature range45℃ to 85℃.
