WJ34 Series Product Realization Host RS-485/232 Interface Signals Convert to standard analog signals to control remote devices. WJ34 series products can be applied to RS-232 / RS-485 bus industrial automation control systems, 4-20mA, 0-5V, 0-10V and other standard signal output, used to control industrial site executive equipment, control equipment, and display instruments, etc. Wait.Products include power isolation, signal isolation, linearization, D / A conversion, and RS-485 serial communication. Each serial port can be connected up to 255 WJ34 series modules, communication mode uses the ASCII code communication protocol and the Modbus RTU communication protocol, automatically identify communication protocols and reply, the baud rate can be set by the code, can hang the same RS with other manufacturers The -485 bus is easy to program.

WJ34 series products are based on a single-chip intelligent monitoring and control system, all user set calibration values, address, baud rates, data formats, checksum, and other configuration information stored in non-volatile memory EEPROM.

WJ34 series products are isolated from industrial standards, manufacturing, signal output / communication interfaces, can withstand 3000VDC isolation voltages, strong anti-interference ability, high reliability. Working temperature range - 45 ° C ~ + 80 ° C.
