Product Overview:

Function Introduction:

The WJ71 product realizes signal acquisition and control between sensors and hosts, used to detect switchsignalsorcontrol device operation. The WJ71 series products can be applied in industrial automation control systems withRS-232/485 bus, measurement and control of switch signals, measurement and output of high and lowlevel signals, aswell as industrial field signal isolation and long-distance transmission, etc. The product includes power conditioning, switch quantity acquisition, relay output, and RS-485 serial
communication. Each serial port can connect up to 255 WJ71 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 WJ71 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-volatilememory EEPROM. The WJ71 series products are designed and manufactured according to industrial standards, with no isolationbetween signal inputs/outputs, strong anti-interference ability, and high reliability. The working temperature rangeis-45 ℃ to+85 ℃.

The WJ71 remote I/O module can be used to measure four switch signals and has four relay signal outputs. 1, Switching signal input and output
Three channel switch signal input, capable of connecting dry contacts and wet contacts. Please refer to thewiringdiagram for details; Ten relay normally open contact output. 2, Communication Protocol
Communication interface: 1 standard RS-485 communication interface or 1 standard RS-232 communicationinterface, please specify when ordering and selecting. 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, 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 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 and protect the module
