Process up to 46 analogue input channels at both low and high rates of sampling.
Call for price
Delphin Technology’s Expert Logger is available in four variants, differing in their number of analogue and digital channels. With just one device, you can independently process up to 46 analogue input channels, at both low and high sampling rates. All channels are galvanically isolated from each other. Measured data undergoes precision recording, monitoring and pre-processing and can be stored internally within the device. LAN, USB, WAN or UMTS / LTE are available to transfer measurement data to a PC or server. Integrated interfaces such as PROFIBUS, Modbus and OPC UA enable optimal connectivity to existing infrastructure.
The Expert Logger is a highly flexible data recording system designed to meet your specific measurement requirements. Simple and quick channel configuration enables the Logger to be efficiently adapted to your requirements and it can be up and running in the shortest possible time.
