The product includes signal isolation, pulse signal capture, signal conversion, and RS-485 serial communication. Each serial port can connect up to 255 WJ167 series modules,
The communication method adopts ASCII code communication protocol or MODBUS RTU communication protocol, and the baud rate can be set by the code, which can be hung with control modules from other manufacturers
On the same RS-485 bus, it is convenient for computer programming
The WJ167 series products are intelligent monitoring and control systems based on microcontrollers, with all user set addresses, baud rates, data formats, and parity calibration
The verification configuration information is stored in the non-volatile memory EEPROM.
The WJ167 series products are designed and manufactured according to industrial standards, with no isolation between signal inputs/outputs, strong anti-interference ability, and high reliability. Working temperature
Temperature range -45 ℃ to+85 ℃.
Function Introduction:
The WJ167 remote I/O module can be used to measure four encoder signals or can be set as an eight channel independent counter.
1. Signal input
4-channel encoder 5V differential signal input or 8-channel 5V differential signal independent counter.
2. Communication protocol
Communication interface: 1 standard RS-485 communication interface or 1 standard RS-232 communication interface, specified 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,
Can achieve network communication with multiple brands of PLC, RTU or computer monitoring systems.
Data format: 10 digits. 1-bit start bit, 8-bit data bit, 1-bit stop bit. No verification.
The communication address (0-255) and baud rate (2400, 4800, 9600, 19200, 38400, 57600, 115200bps) can be set; communication
The longest distance of the network can reach 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. WiFi communication protocol
Communication interface: WiFi network interface. It can be connected to WiFi in the local area network and then to Ethernet.
Communication protocol: Supports MQTT protocol and can connect to various MQTT platforms such as Alibaba Cloud, Tencent Cloud, Huawei Cloud, China Mobile IoT OneNET, Private Cloud, etc
The server. MODBUS TCP protocol can also be used to achieve industrial Ethernet data exchange.
It also supports communication protocols such as TCP/UDP/WebSocket.
Network cache: 2K Bytes (both receive and send)
Communication response time: less than 10mS. 4. Anti-interference
Checksum can be set as needed. There are transient suppression diodes inside the module, which can effectively suppress various surge pulses and protect the module
Word filtering can also effectively suppress power frequency interference from the power grid.
