Product overview:
WJ33 series products realize the isolation conversion of the host RS-485/232 interface signal into a standard analog signal, which is used to control remote. The WJ33 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 outputs, which are used to control industrial field actuators, control devices and display instruments, etc.The product includes power isolation, signal isolation, linearization, D/A conversion and RS-485 serial communication. Each serial port can connect up to 255J33 series modules, and the communication mode uses the ASCII code communication protocol and MODBUS RTU communication protocol. It automatically identifies the communication protocol and responds. Theaud rate can be set by the code, and can be hung on the same RS-485 bus with other manufacturers' control modules, which is convenient for computer programming.The WJ33 series products are intelligent monitoring and control systems based on microcontrollers. All user-set calibration values, addresses, baud rates, data formats, checks, and status, etc., are stored in non-volatile memory EEPROM.
The WJ33 series products are designed and manufactured according to industrial standards. signal output / communication interface is isolated and can withstand 3000VDC of isolation voltage. It has strong anti-interference ability and high reliability. The operating temperature is -45℃ to 80℃.
