Product Overview: The WJ168 product realizes signal acquisition between sensors and hosts, used to decode encoder signals. TheWJ168 series products can be applied to industrial automation control systems, automated machine tools, industrial robots, three coordinate positioning systems, displacement measurement, stroke measurement, angle measurement, speedmeasurement, flow measurement, product counting, and more. The product includes signal acquisition, pulse signal capture, signal conversion, and RS-485 serial communication.Each serial port can connect up to 255 WJ168 series modules, and the communication method adopts ASCII codecommunication protocol or MODBUS RTU communication protocol. The baud rate can be set by code and canbehungon the same RS-485 bus as control modules from other manufacturers, making it easy for computer programming.

The WJ168 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 WJ168 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 ℃.

Function Introduction:

The WJ168 remote I/O module can be used to measure 10 encoder signals, and can also be set as a 20 channel independent counter or DI status measurement. 1. Signal input 10 encoder signal inputs or 20 independent counters, can be connected to dry and wet contacts. Please refer tothewiringdiagram for details. 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. No verification. 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
