Product Overview:
The WJ30 product realizes signal acquisition between sensors and the host to detect analog signals. The WJ30 series products can be applied to the RS-232/485 bus
Industrial automation control system, 4-20mA/0-5V signal measurement, monitoring and control, as well as industrial site signal isolation and long-distance transmission, etc.
The products include power isolation, signal isolation, linearization, A/D conversion, and RS-485 serial communication. Each serial port can connect up to 255 WJ30 series
Column module, communication mode supports MODBUS RTU communication protocol, default address is 01, baud rate is 9600, data format: 10 bits, starting with 1 bit
Bit, 8-bit data bit, 1-bit stop bit, no checksum. It also supports ASCII communication protocol, and the baud rate can be set by the code, which can be controlled by other manufacturers
The modules are mounted on the same RS-485 bus for easy computer programming.
