Product Overview:
WJ169 product realizes signal acquisition between sensor and host to decode encoder signal.WJ169 series productscan be used in RS-232/485 and WiFi 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. The products include signal isolation, pulse signal capture, signal conversion and RS-485 serial communication.Each serial port can connect 255 WJ169 series modules at most. The communication mode adoptsASCII code communication protocol or MODBUS RTU communication protocol. The baud rate can be set bycode, andcan be linked to the same RS-485 bus with the control module of other manufacturers, which is convenient for computerprogramming.
WJ169 series products are intelligent monitoring and control systems based on single chip microcomputer. All userset configuration information such as address, baud rate, IP address and parameter setting are stored in non-volatilememory EEPROM. WJ169 series products are designed and manufactured according to industrial standards, with strong anti-interference ability and high reliability.Operating temperature range -45 ℃~+80 ℃.
Function introduction: WJ169 remote I/O module can be used to measure 8-channel encoder signals, and can also be set as a 16 channel independent counter or DI status measurement. 1. Signal input 8-channel encoder signal input or 16 channel independent counter can be connected to dry contact andwet contact.Please refer to the wiring diagram for details. 2. RS485/232 communication protocol Communication interface: one standard RS-485 communication interface or one standard RS-232 communicationinterface, which shall be noted when ordering and selecting models. Communication protocol: supports two protocols, the character protocol defined by the commandset andtheMODBUS 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-bit start bit, 8-bit data bit, 1-bit stop bit.No calibration. 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, which is connectedbytwisted pair shielded cables. High anti-interference design of communication interface, ± 15KV ESD protection, communication responsetimeless than 100mS. 3. WiFi communication protocol Communication interface: WiFi network interface.It can be connected to WiFi in the LAN and then to Ethernet. Communication protocol: It supports MQTT protocol and can connect to various MQTT servers such as AlibabaCloud, Tencent Cloud, Huawei Cloud, China Mobile IOT OneNET, Private Cloud, etc.MODBUSTCPprotocol can also be used to realize data exchange of industrial Ethernet. It also supports TCP/UDP/WebSocket and other communication protocols. Network cache: 2K Byte (both receiving and sending) Communication response time: less than 10mS.4. Anti interference There are transient suppression diodes inside the module, which can effectively suppress various surge pulses, protect the module, internal digital filtering, and also can well suppress power frequency interference fromthepower grid.The built-in watchdog can effectively prevent module downtime.
