Product Overview:
The WJ99 product realizes signal acquisition between sensors and the host, used to decode grating ruler magnetic grating ruler encoder signals. The WJ99 series products can be applied in
Ethernet bus industrial automation control system, automated machine tools, industrial robots, three coordinate positioning system, displacement measurement, stroke measurement, angle measurement,
Speed measurement, flow measurement, product counting, and so on.
The product includes signal isolation, pulse signal capture, signal conversion, and Ethernet communication. The communication method adopts ASCII code communication protocol or MODBUS TCP
The communication protocol, TCP, is a transport layer based protocol that is widely used, connection oriented, and reliable. Users can directly set the module IP address on the webpage
Address, subnet mask, etc
The WJ99 series products are intelligent monitoring and control systems based on microcontrollers, where user configured module IP addresses, subnet masks, and other configuration information are stored
In the non-volatile memory EEPROM.
The WJ99 series products are designed and manufactured according to industrial standards, with isolation between signal input/communication, strong anti-interference ability, and high reliability. Working temperature range
Surrounding -40 ℃ to+85 ℃.
Function Introduction:
The WJ99 remote I/O module can be used to measure eight encoder signals, or can be set as a 16 channel independent counter or DI state measurement.
1. Signal input
8-channel encoder signal input or 16 channel DI independent counter, can be connected to dry and wet contacts, please refer to the wiring diagram for details.
Note: When used as an independent counter input for DI, channels A0~A7 are high-speed channels, and the frequency can reach 5MHz; Channels B0 to B7 are low-speed passes
Dao, with a maximum frequency of 20KHz. 2. Communication protocol
Communication interface: RJ-45 network interface. The two indicator lights at the network port position, after the network cable is plugged in, the Link light (green light) will remain on and the Data light (yellow light) will remain on
It will flicker irregularly.
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. 3. 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.
