Delphin Technology Loggito Series Data Logger

Description

Compact stand-alone data logger from Delphin Technology.

The Loggito Logger is an autonomous data logger with internal measurement data storage capabilities. Integrated software channels enable easy configuration of monitoring and calculation procedures. The device has an extended range of possible applications, including monitoring and alerting.

Loggito Gate version is the ideal solution for logging and recording machine data in measurement networks, as well as for control. With the integrated Ethernet connection and the available OPC UA (server/client) and Modbus TCP standards, it can be used multifunctionally. From a pure Modbus or OPC logger to a transmission solution in a DAQ software, many applications are possible.

The Loggito USB is an entry-level version in Delphin’s measurement technology. Loggito USB can be used either for PC-based measurement or as an extension to the Loggito Logger.
