product description:

WJ33 Series Product Realization Host RS-485/232 Interface Signals Convert to standard analog signals to control remote devices. WJ33 series can be applied to standard signal outputs such as RS-232 / RS-485 bus industrial automation control system, 4-20mA, 0-5V, 0-10V, to control the implementation equipment, control equipment and display instrumentation of industrial scenes, 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 WJ33 series modules, the communication mode uses the ASCII code communication protocol and the Modbus RTU communication protocol, automatically identifies the communication protocol and reply, the baud rate can be set by the code setting, can hang the same RS with other manufacturers' control modules The -485 bus is easy to program.

The WJ33 series is based on a single-chip intelligent monitoring and control system, all user setting calibration values, information, baud rates, data formats, checkiga, and other configuration information stored in non-volatile memory EEPROM.

WJ33 series products are isolated from industrial standards, manufacturing, signal output / communication interface, can withstand 3000VDC isolation voltages, strong anti-interference ability, high reliability. Working temperature range - 45 ° C ~ + 80 ° C.
