The GL 220 Midi-Logger

March 2013 Industrial Computer Hardware

With its colour monitor and internal memory, the GL220 is a compact, lightweight, multi-channel data-logger. It provides 10 analog measurement channels, in addition to four logic and pulse inputs. The GL220 also supports one external trigger input and four alarm outputs and is equipped with a 2 GB internal flash memory to allow the direct capture of acquired data via the built-in USB port. Alternatively, the USB interface may be connected to a PC to allow data upload in real-time or from memory, as well as remote configuration and real-time data acquisition.

Each GL220 analogue channel can measure from 20 mV to 50 V across 11 programmable measurement ranges, with each channel electrically isolated from the others and from instrument ground to allow accurate and safe measurements in industrial applications where ground potential differences are common.

The four discrete input channels can be used for counting and rotational speed measurement applications and the alarm outputs can be programmed to trigger as a function of analogue input signal level, pulse judgment or a logic pattern. Sample intervals can be programmed to be one of 16 values ranging from 10 ms to one hour.

The focal point of the GL220 is its built-in colour display that allows real-time trending, data review and complete instrument configuration. The package includes a Windows application for direct capture, measurement and monitoring of GL220 data. In addition to waveform and data value capture and display, the application can export data to an Excel file for further analysis and report creation. The software includes built-in help for quick reference.
