Product Overview:
The WJ203 series products implement remote devices such as host RS-485/232 interface signal isolation control solenoid valves, proportional valves, LED lights, DC motors, etc. The WJ203 series products can be applied to RS-485 bus industrial automation control systems, with 0~± 23V or 0~± 250mA outputs, used to control execution equipment in industrial sites,
Control equipment and lighting, etc.
The product includes power isolation, signal isolation, D/A conversion, and RS-485 serial communication. Each serial port can connect up to 255 WJ203 series modules, communication method
Using ASCII code communication protocol and MODBUS RTU communication protocol, the communication protocol is automatically recognized and replied to. The baud rate can be set by code and can be compatible with other manufacturers
The control module is mounted on the same RS-485 bus for easy computer programming
