 Product Overview:
 The WJ33 series products achieve the isolation and conversion of host RS-485/232 interface signals into standard
 analog signals for controlling remote devices. The WJ33 series products can be applied in industrial automation control
 systems based on RS-232/RS-485 bus, with standard signal outputs such as 4-20mA, 0-5V, 0-10V, etc., used to control
 execution equipment, control equipment, display instruments, etc. in industrial sites.
 The product includes power isolation, signal isolation, linearization, D/A conversion, and RS-485 serial communication.
 Each serial port can connect up to 255 WJ33 series modules, using ASCII code communication protocol and MODBUS RTU  communication protocol for communication. The communication protocol is automatically recognized and replied to, and the
 baud rate can be set by code. It can be connected to other manufacturers' control modules on the same RS-485 bus for easy
 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, checksum statuses, and other configuration information are stored in
 non-volatile memory EEPROM.
 The WJ33 series products are designed and manufactured according to industrial standards, with isolation between signal
 output/communication interfaces. They can withstand an isolation voltage of 3000VDC, have strong anti-interference ability,
 and high reliability. The working temperature range is-45 ℃ to+80 ℃
