GL 220 data-logger with colour monitor
March 2015
Data Acquisition & Telemetry
With its colour monitor and internal memory the GL220 is a compact, lightweight, multi-channel data-logger that provides 10 analog measurement channels, in addition to four channels each of discrete logic and pulse inputs. The GL220 also supports one external trigger input and four alarm outputs. It is equipped with a 2 GB internal Flash memory to allow the direct capture of acquired data, and its built-in USB port may be used to connect any standard USB Flash drive for incremental capacity. 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. Other features and benefits include:
* Wide voltage measurement range: Each GL220 analog channel can measure from 20 mV to 50 VFS across eleven programmable measurement ranges.
* Full electrical isolation per channel: Each analog GL220 channel is electrically isolated from all others and from instrument ground to allow accurate and safe measurements in industrial applications where ground potential differences are common.
* Humidity measurements: Use the GL220 to measure humidity with an optional sensor.
* Voltage, current and temperature measurements: Use the GL220 to measure voltages, currents, 4-20 mA process currents, as well as thermocouple-based temperatures.
* Four pulse inputs for speed and counting measurements: The GL220 provides four discrete input channels that can be used for counting and rotational speed measurement applications.
* Real time and post-recorded calculations: The GL220 may be programmed to calculate average value, peak value, minimum value, RMS and arithmetic operations.
* Four alarm outputs: Program the GL220 to trigger its alarm outputs as a function of analog input signal level judgment, pulse judgment, or logic pattern.
* Bright TFT LCD colour display: The focal point of the GL220 is its 4,3” built-in WQVGA colour display that allows real-time trending, data review, and complete instrument configuration.
* Flexible triggering options: The GL220 allows data capture to be started or stopped based upon signal level, an external event, date/time, alarm, duration, or Boolean channel combinations. Analog signal triggers can be programmed based upon level and window tests: above threshold, below threshold, inside window, or outside window.
* PC connectivity and memory expansion via USB interface: Allows data transfer to the PC either in real time or from the GL220’s memory. Also allows complete configuration of the GL220. Connect any standard USB Flash Drive to the USB port for external memory expansion.
* PC software bundle included: The GL220 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.
