Product Description

Eight DI and eight DO channels, switch isolation to RS-485/232, data acquisition
remote I/O module WJ65

Product Overview:
The WJ65 product realizes signal acquisition and control between sensors and hosts, used to detect switch signals
or control device operation.
The WJ65 series products can be applied in industrial automation control systems with
RS-232/485 bus, measurement and control of switch signals, measurement and output of high and low level signals, as
well as industrial field signal isolation and long-distance transmission, etc.
The product includes power conditioning, switch quantity acquisition, switch quantity output, and RS-485 serial
communication.
Each serial port can connect up to 255 WJ65 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 WJ65 series products are intelligent monitoring and control systems based on microcontrollers. All user set
configuration information such as address, baud rate, data format, checksum status, etc. are stored in non-volatile
memory EEPROM.
The WJ65 series products are designed and manufactured according to industrial standards, with 3000V triple
isolation between signal input, output, and communication interfaces, strong anti-interference ability, and high reliability.
The working temperature range is -45 ℃ to+85 ℃.

Function Introduction:

WJ65 General Parameters:

The WJ65 remote I/O module can be used to measure eight switch signals and has eight switch outputs.
1. Switching signal input and output
8-channel switch signal input, capable of connecting dry and wet contacts. Please refer to the wiring diagram for
details;
8-channel switch signal output with open collector output, can be commanded to set internal pull-up
output.
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
MODBUS RTU communication 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, 1 stop bit, no checksum.
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
Parity check can be set as needed.
There is a transient suppression diode inside the module, which can effectively
suppress various surge pulses and protect the module.
