Data logger module NDAS-8224

A 4-channel seismic data logger module is designed for battery-powered autonomous data acquisition systems including ocean-bottom seismic stations. The module has an extremely low power consumption in the operation mode - less than 300 mW. It is totally optimized for operating with MTSS-2003 three-component seismic sensor and СМЕ4211/4311OBS low power ocean-bottom seismometers.

The data transfer and system configuration can be carried out either via wired USB or wireless Wi-Fi connection while 32 GB of onboard NVRAM allows for a long-term autonomous recording. The data logger is fully operational while powered from a USB port. 

The wireless link makes it possible to set up the system as well as to perform the quality analysis of the data being registered remotely without any interruption to the system. The data logger is able to emit test signals such as various frequency sinus or 1-second length pulse and has an additional ±2.5 V DC power source for powering hydrophones.
