Product Overview:

WJ32 Function Introduction:

The WJ32 series products achieve the isolation and conversion of host RS-485/232 interface signals into standardanalog signals for controlling remote devices. The WJ32 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 WJ32 series modules, using ASCII code communication protocol and MODBUSRTUcommunication protocol for communication. The communication protocol is automatically recognized and replied to, 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 WJ32 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 WJ32 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 WJ32 signal isolation D/A conversion module can be used to output 4-channel common ground current or voltagesignals.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 selection of the 4-channel outputmust be the same. 2, Communication Protocol
Communication interface: 1 standard RS-485 communication interface or 1 standard RS-232 communication interface, please specify when ordering and selecting. Additionally, there is a WiFi network that supports multiple communication methods such as TCP/UDP/MQTT. 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) can beset;
The communication network can reach a maximum distance of 1200 meters and is connected throughtwistedpair 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.
