product description:

WJ126 product implements multiple signal acquisitions between sensors and hosts to detect temperature signals. WJ126 series products can be applied to RS-485 bus industrial automation control systems, temperature signal measurement, monitoring and control, etc.

Products include power isolation, signal isolation, linearization, A / D conversion, and RS-485 serial communication. Each serial port can be connected up to 255 WJ126 series modules, communication mode uses ASCII code communication protocol or Modbus RTU communication protocol, address and baud rate can be set by code settings, can hang on the same RS-485 bus with other manufacturers' control modules, It is easy to program.

WJ126 series products are based on a single-chip intelligent monitoring and control system, all user setting calibration values, address, baud rates, data formats, checksum, and other configuration information stored in non-volatile memory EEPROM.

WJ126 series products are isolated between industrial standards, manufacturing, signal input / output, can withstand 1000VDC isolation voltages, strong anti-interference ability, high reliability. Working temperature range - 45 ° C ~ + 85 ° C.
