Details
This digital acquirer allows you to acquire up to 36 channels in multiples of 6, placed in a single cabinet with wall or floor mounting.
The communication system via LAN cable allows to cover distances up to 300m; alternatively, the connection to the system from remote can be made via 4G modem, fiber optic, WiFi and more on request.
The configuration is done through a simple WEB interface without the need for dedicated applications.
VIBROSOFT or SOLWEB data processing software, enables efficient dynamic monitoring networks.
