Frequently Asked Questions
What is the maximum signal frequency the WJ97 can handle?
The module supports high-speed counting with a frequency range of up to 5MHz for all channels simultaneously.
Can the module power the connected grating rulers?
Yes, the WJ97 module can output a 5V power supply specifically to power the grating rulers.
Does the device lose its count data during a power failure?
No, the encoder count value supports automatic power-off saving, ensuring data integrity when power is restored.
Which communication protocols are supported?
The module supports Modbus TCP, MQTT (for cloud services like Alibaba/Tencent/Huawei Cloud), and TCP/UDP/WebSocket protocols.
Is special software required to view the data?
No special software is required. Users can view all data and set module parameters directly through a web browser.
What is the installation method?
The WJ97 is designed for standard DIN35 rail installation, making it very convenient for centralized wiring in industrial cabinets.
