 Product Overview:

 Function Introduction:

 The WJ168 product realizes signal acquisition between sensors and hosts, used to decode encoder signals. The
 WJ168 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, speed
 measurement, 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 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 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-volatile
 memory EEPROM.
 The WJ168 series products are designed and manufactured according to industrial standards, with no isolation
 between signal inputs/outputs, strong anti-interference ability, and high reliability. The working temperature range is-45 ℃to+85 ℃.

 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 to the wiring
 diagram for details.
 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. No verification.
 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.
