Product Overview:
The WJ31 series realize host RS-485/232 interface signal isolation converted into a standard analog signal, to control
the remote device. WJ31 products can be applied to RS-232/485 bus industrial automation control system,4-20mA /
0-5V/0-10V standard signal output, to control industrial site execution set equipment, control equipment and display
instrument.
Products include power supply isolation, signal isolation, linearization, D/A conversion and RS-485 serial
communication. Each serial interface can connect up to 256 pieces WJ21 Series modules, communication using ASCII
code or MODBUS RTU communication protocol, and its instruction set compatible with the ADAM modules, baud rate
can been set by the code, with other manufacturers control module hang in the same RS-485 bus for easy programming.
