Expert Logger 400 – Data acquisition and test stand automation using an OPC UA interface

Delphin Technology AG has extended its Expert Logger range with the new type 400 model equipped with an OPC UA Client/Server interface. This enhancement to the independently functioning data logger system ideally equips it for the universal exchange of measurement data at field level and for the requirements of Industry 4.0. The Expert Logger device is also equipped with ProfiBus, ModBus, CAN-Bus and serial interfaces. PCs are connected via USB, LAN, WLAN and LTE.

The new type 400 is equipped with 16 universally usable, differential analog inputs for measuring mV and mA signals or any type of thermocouple. 24-bit precision and a maximum rate of 1000 measurements per second meets the highest demands required from a data logger. The new Expert Logger also has the option of measuring Pt100(0) sensors using 2, 3 or 4 wire technology or DMS. The device has a total of 24 switchable digital inputs/outputs which can record edge and fault events at microsecond precision as well as output alerts. A total of six analog outputs enable the operation of regulating and control elements.

The Expert Logger series offer a range of model types with 16 to 46 analog inputs which are ideal for independent data acquisition and test stand automation. Monitoring functions can also be performed independently within the device. Measurement data and limit value violations can be immediately transmitted to subsystems via OPC UA. The OPC UA interface also offers data exchange to PLC systems and connecting to PLT systems.

Furthermore, the ProfiSignal Go software – for portraying and analysing measurement data online and offline – remains a fixed element of every Expert Logger device.
