Product Overview:
Function Introduction:
WJ128
The WJ128 product implements signal acquisition between sensors and hosts for detecting analog signals. The
WJ128 series products can be applied to industrial automation control systems with RS-232/485 bus, 4-20mA/0-5V
signal measurement and monitoring, as well as 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 WJ128 series modules, and the communication method adopts
ASCII code communication protocol or MODBUS RTU communication protocol. The baud rate can be set by code and
can be hung on the same RS-485 bus as control modules from other manufacturers, making it easy for computer
programming The WJ128 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 WJ128 series products are designed and manufactured according to industrial standards, with isolation between
signal inputs/outputs, capable of withstanding 1000VDC isolation voltage, strong anti-interference ability, and high
reliability. The working temperature range is-45 ℃ to+85 ℃.
The WJ128 signal isolation acquisition module can be used to measure eight voltage or current signals.
1,Analog signal input
12 bit acquisition accuracy, 8 analog signal inputs. All signal input ranges have been calibrated before the product
leaves the factory. During use, users can also easily program and calibrate themselves. Please refer to the product
selection for specific current or voltage input range.
2,Communication Protocol
Communication interface: 1 standard RS-485 communication interface or 1 standard RS-232 communication
interface, please specify when ordering and selecting.
Communication Protocol: Supports two protocols, the character protocol defined by the command set and the
MODBUSRTUcommunication protocol. The module automatically recognizes communication
protocols and can achieve 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 be set;
The communication network can reach a maximum distance of 1200 meters and is connected through
twisted pair shielded cables.
High anti-interference design of communication interface, ± 15KV ESD protection, communication response time
less than 100mS.
3,anti-interference
Checksums can be set as needed. There is a transient suppression diode inside the module, which can effectively
suppress various surge pulses, protect the module, and the internal digital filter can also effectively suppress power
frequency interference from the power grid
