product description:
WJ69 product realizes the signal acquisition between the sensor and the host to decode the encoder signal. WJ69 series products can be used in RS-232/485 bus 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, etc.
Products include signal isolation, pulse signal capture, signal conversion and RS-485 serial communication. Each serial port can connect up to 255 WJ69 series modules. The communication method adopts ASCII code communication protocol or MODBUS RTU communication protocol. The baud rate can be set by code. It can be connected to the same RS-485 bus with other manufacturers' control modules, which is convenient for computers. Programming.

       WJ69 series products are intelligent monitoring and control systems based on single-chip microcomputers. All user-set address, baud rate, data format, checksum status and other configuration information are stored in non-volatile memory EEPROM.
WJ69 series products are designed and manufactured in accordance with industrial standards. There is no isolation between signal input and output, with strong anti-interference ability and high reliability. Operating temperature range-45℃~+85℃.



Function introduction:
The WJ69 remote I/O module can be used to measure eight-channel encoder signals, and it can also be set as a 16-channel independent counter or DI state measurement.
1. Signal input
8 encoder signal inputs or 16 independent counters can be connected to dry contacts 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 MODBUS RTU communication protocol. The module automatically recognizes the communication protocol and can realize network communication with various brands of PLC, RTU or computer monitoring systems.
Data format: 10 bits. 1 start bit, 8 data bits, 1 stop bit. No verification.
The communication address (0~255) and baud rate (2400, 4800, 9600, 19200, 38400, 57600, 115200bps) can be set; the longest distance of the communication network can reach 1200 meters, and it is connected by twisted-pair shielded cable.
The communication interface is designed with high anti-interference, ±15KV ESD protection, and the communication response time is less than 100mS.
3. Anti-interference
The checksum can be set as required. There are transient suppression diodes inside the module, which can effectively suppress various surge pulses, protect the module, and the internal digital filter can also suppress the power frequency interference from the power grid.
