PX01 is a 1U rack-type smart earthquake central datalogger featuring dynamic voice alarms, relay control outputs with the ability to connect up to 5 Sanlien seismic sensors. PX01 is equipped with an LCD screen for parameters, system state-of-health, and current activity value display. Moreover, it supports NTP time calibration, acting as both the server and client. The N-of-M voting algorithm is built-in PX01 by that the onsite earthquake early warning system is able to trigger emergency shutdown, voice alarm broadcasting, or text message delivering via SMS or LINE App. The flexible and open Modbus protocol is also provided for users to integrate PX01 into the SCADA, MES, or other management programs easily.

Not only Sanlien seismic sensors are able to feed data into PX01 for real-time seismic monitoring and onsite control outputs, but also 3rd-party accelerographs can be integrated via the SeedLink protocol to achieve this purpose. Event data and logs are stored in PX01 microSD card and feasible to be forwarded on to users cloud by its FTP function. In sum, PX01 is a cost-effective datalogger for regional/onsite earthquake early warning, structural health monitoring, and any vibration applications.
