Eight-channel IEPE vibration sensor data high speed synchronization network acquisition module WJ288

product description:

WJ288 products are an Internet of Things and Industrial Ethernet Acquisition Modules that realize sensor data acquisition and send to the network. Iepe is an abbreviation of "Integrated Electronics Piezo-Electric", ie integrated circuit type piezoelectric sensor. This piezoelectric sensor with built-in electronic devices has become standards in the industry. The semiconductor circuit converts the high impedance signal of the piezoelectric sensor into a low impedance voltage signal that is easier to transmit. With IEPE, you can achieve power supply and signal transmission with a standard cable for any length, and measurement errors will not be generated due to cable movement.

WJ288 series products include power conditioning, analog synchronous acquisition, constant current source output, and RJ-45 network interface communications. The communication method uses the UDP protocol. The user can set the module IP address, subnet mask, and the like.

The WJ288 series is based on the intelligent monitoring system of the microcontroller, and the user set the module IP address, the subnet mask and other configuration information stored in the non-volatile memory EEPROM.

WJ288 series products are designed, manufactured, and highly reliable, and reliable. Working temperature range - 45 ° C ~ + 85 ° C.
