Details
Communication system via LAN. The connection to the system can be made remotely via 3G modem, 4G, FIBER OPTIC, WiFi.
It is equipped with LCD display (optional) and membrane keyboard for status display and control function.
The software DYMASOFT, integrated with the data processing software VIBROSOFT or SOLWEB, allows the realization of efficient dynamic monitoring networks of structures according to the reference standards, while the version in continuous recording via miniSEED protocol and SEEDlink transmission for seismic and microseismic monitoring networks.
The DYMAS24 MASTER-V is available in a version with terminal block connections (for fixed installations) or in a version with inputs and outputs with MIL IP65 connectors for temporary installations.
