🚀 Product Description

WJ288: Eight-Channel IEPE Vibration Sensor Data High-Speed Synchronous Network Acquisition Module

The WJ288 product is an IoT and industrial Ethernet acquisition module that enables sensor data collection and transmission to the network. IEPE stands for Integrated Electronics Piezo Electronic, which is a piezoelectric sensor with built-in electronic components. This technology converts high impedance signals from piezoelectric sensors into low impedance voltage signals for easier transmission over standard cables without measurement errors caused by cable movement.

Frequently Asked Questions
What type of sensors does the WJ288 support?
The WJ288 is specifically designed for IEPE (Integrated Electronics Piezo Electronic) vibration sensors. It includes a built-in 4mA constant current source to power these sensors directly.
How fast can the module collect data?
The module features a 16-bit AD converter with a synchronous acquisition speed of 20K SPS (Samples Per Second) across all eight channels.
What communication protocols are used for data transmission?
Data is automatically reported through the RJ-45 network interface using UDP or TCP protocols, making it easy to integrate into industrial IoT systems.
Can the module operate in extreme outdoor environments?
Yes, the module is designed for industrial standards with a wide operating temperature range from -45℃ to +80℃. For harsh environments like ports or bridges, an optional metal waterproof casing is available.
Is the module configuration permanent?
Yes, user-set parameters such as IP addresses and subnet masks are stored in non-volatile EEPROM memory, ensuring settings are retained even after power loss.
What are the power requirements?
The module requires a standard 24VDC (±10%) power supply and has an efficient power consumption of less than 3W.
