Product Overview:

WJ34 Function Introduction:

The WJ34 series products achieve the isolation and conversion of host RS-485/232 interface signals into standardanalog signals for controlling remote devices. The WJ34 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 The product includes power isolation, signal isolation, linearization, D/A conversion, and RS-485 serial communication. Each serial port can connect up to 255 WJ34 series modules, using ASCII code communication protocol and MODBUSRTUcommunication protocol for communication. The communication protocol is automatically recognized and repliedto, andthebaud rate can be set by code. It can be connected to other manufacturers' control modules on the same RS-485 bus for easycomputer programming. The WJ34 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 storedinnon-volatile memory EEPROM. The WJ34 series products are designed and manufactured according to industrial standards, with isolation betweensignaloutput/communication interfaces. They can withstand an isolation voltage of 3000VDC, have strong anti-interferenceability, and high reliability. The working temperature range is -45 ℃ to+80 ℃

The WJ34 signal isolation D/A conversion module can be used to output 12 common ground current or voltage signals. 1, Analog signal output
12 bit output accuracy, all signal output ranges have been calibrated before the product leaves the factory. Duringuse, users can also easily program and calibrate themselves. Please refer to the product selection for the specific current or voltage output range. The 12 output options must bethesame. 2, Communication Protocol
Communication interface: 1 standard RS-485 communication interface and 1 standard RS-232 communicationinterface, which can communicate simultaneously without interfering with each other. Communication Protocol: Supports two protocols, the character protocol defined by the command set and the MODBUSRTU communication protocol. The module automatically recognizes communication protocols andcanachieve network communication with various brands of PLCs, RTUs, or computer monitoring systems. Data format: 10 digits. 1 start bit, 8 data bits, and 1 stop bit. The communication address (0-255) and baud rate (2400, 4800, 9600, 19200, 38400, 57600, 115200bps) canbeset;
The communication network can reach a maximum distance of 1200 meters and is connected throughtwisted pair shielded cables. High anti-interference design of communication interface, ± 15KV ESD protection, communication response timelessthan 100mS.3, anti-interference
Checksums can be set as needed. There is a transient suppression diode inside the module, which can effectivelysuppress various surge pulses, protect the module, and the internal digital filter can also effectively suppress power
frequency interference from the power grid.
