Product Overview:

Function Introduction:

The WJ123 product implements signal acquisition between sensors and hosts for detecting analog signals. TheWJ123 series products can be applied in RS-485 bus industrial automation control systems, various potentiometer
resistance signal measurement, monitoring, industrial field signal isolation, and long-distance transmission, etc. The product includes power isolation, signal isolation, linearization, A/D conversion, and RS-485 serial
communication. Each serial port can connect up to 255 WJ123 series modules, and the communication methodadoptsASCII code communication protocol or MODBUS RTU communication protocol. The baud rate can be set bycodeandcan be hung on the same RS-485 bus as control modules from other manufacturers, making it easy for computer
programming

The WJ123 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 informationarestoredin non-volatile memory EEPROM. The WJ123 series products are designed and manufactured according to industrial standards, with isolationbetweensignal inputs/outputs. They can withstand 1000VDC isolation voltage, have strong anti-interference ability, andhighreliability. The working temperature range is -40 ℃ to+85 ℃

The WJ123 signal isolation acquisition module can be used to measure the resistance signal of a three wire
potentiometer. 1, Potentiometer signal input
12 bit acquisition accuracy, potentiometer resistance signal input. The product has been fully calibratedbeforeleaving the factory. Users do not need to calibrate. 2, Communication Protocol
Communication interface: 1 standard RS-485 communication interface. Communication Protocol: Supports two protocols, the character protocol defined by the command set andtheMODBUS RTU communication protocol. The module automatically recognizes communicationprotocols and can achieve network communication with various brands of PLCs, RTUs, or computermonitoring systems. Data format: 10 digits. 1 start bit, 8 data bits, 1 stop bit, no checksum. 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 connectedthroughtwisted pair shielded cables. High anti-interference design of communication interface, ± 15KV ESD protection, communication responsetimeless than 100mS. 3, anti-interference
Checksums can be set as needed. There is a transient suppression diode inside the module, which caneffectivelysuppress various surge pulses, protect the module, and the internal digital filter can also effectively suppresspowerfrequency interference from the power grid.
