Product overview:            
Wj63 product realizes signal acquisition between sensor and host, which is used for pulse signal counting and equipment control. Wj63 series products can be used in RS-232 / 485 bus industrial automation control system, photoelectric switch signal counting measurement, PWM signal output and frequency measurement, etc.            
Products include signal isolation, pulse signal capture, signal conversion and RS-485 serial communication. Each serial port can be connected with 255 wj63 series modules at most. The communication mode adopts ASCII code communication protocol or Modbus RTU communication protocol. The baud rate can be set by code. It can be hung on the same RS-485 bus with the control modules of other manufacturers, which is convenient for computer programming.           
 Wj63 series products are intelligent monitoring and control system based on single chip microcomputer. All configuration information such as address, baud rate, data format, verification and status set by users are stored in non-volatile memory EEPROM.            Wj63 series products are designed and manufactured according to industrial standards, with signal input / output isolated, can withstand 3000vdc isolation voltage, strong anti-interference ability and high reliability. Operating temperature range - 45 ℃ ~ + 85 ℃.            

Function introduction:            
Wj63 remote I / O module can be used to measure eight channel switching signal and has eight channel switching output. It can be used as 8-channel counter or 8-channel frequency measurement,            It can also output 8 PWM signals.            
1. On off signal input and output            8-way switch signal input can be connected to dry contact and wet contact, please refer to the wiring diagram for details; 8-way switch signal output collector open circuit output.            
2. Communication protocol            Communication interface: one standard RS-485 communication interface or one standard RS-232 communication interface, which shall be indicated during ordering and selection.            Communication protocol: support two protocols, character protocol defined by command set and Modbus RTU communication protocol. The module automatically identifies the communication protocol, and can realize network communication with various brands of PLC, RTU or computer monitoring system.            Data format: 10 bits. 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 maximum distance of the communication network can reach 1200 meters, which is connected by twisted shielded cable.            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 are transient suppression diodes in the module, which can effectively suppress various surge pulses, protect the module, internal digital filtering, and also can well suppress the power frequency interference from the power grid.
