GL820 Data Logger

Product Highlights

  • View the Multimedia Demonstration videos for an in-depth look at some of the many great features in the GL820.
  • Built-in 5.7" TFT LCD Color Display
  • Stand-alone or PC-connected operation
  • 20 Analog Channels Standard, Expandable to 200
  • Input-to-output and channel-to-channel Isolation
  • USB and Ethernet PC Interfaces

With its color monitor and internal memory the GL820 is a compact, lightweight, multi-channel data logger that provides 20 standard analog measurement channels, expandable to 200. The GL820 is equipped with a large 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 or the integral Ethernet port may be connected to a PC to allow data upload in real time or from memory, as well as local or remote configuration and real time data acquisition. The Ethernet feature includes WEB and FTP server functions, which allows monitoring from a remote location as well as data transfer.

Wide Voltage Measurement Range

Each GL820 analog channel can measure from 20 mV to 50 VFS across eleven programmable measurement ranges.

Full Electrical Isolation Per Channel

Each analog GL820 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.

Voltage, Current, and Temperature Measurement Functions

Use the GL820 to measure voltages, currents, 4-20 mA process currents, as well as thermocouple- and RTD-based temperatures.

Four Unique "Pulse" Inputs for Discrete Measurements

The GL820 provides discrete input channels that can be used for counting and rotational speed measurement applications. Or program the discrete inputs as simple logic level input channels.

Four Alarm Outputs

Program the GL820 to trigger its open-collector outputs as a function of analog input signal level judgment, pulse judgment, or logic pattern.

Wide Sample Interval Selections

Sample intervals can be programmed to be one of sixteen values ranging from 10 ms to one hour.

Bright TFT LCD Color Display

The focal point of the GL820 is its built-in 5.7-inch color display that allows real time trending, data review, and complete instrument configuration.

Engineering Units Scaling

Each GL820 channel allows up to four break points to be programmed for accurate scaling into meaningful units like psi, grams, newtons, gallons per minute, etc.

Flexible Triggering Options

The GL820 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.

Real Time and Post-recorded Calculations

The GL820 may be programmed to calculate average value, peak value, minimum value, rms, and arithmetic operations (+,-,×,/) between channels.

Flexible Power Requirements

Power the GL820 from its provided international AC adaptor, from an optional built-in battery pack, or from any 9 to 24 VDC source using an optional cable.

PC Connectivity via USB or Ethernet

Allows data transfer to the PC either in real time or from the GL820's memory. Also allows complete configuration of the GL820.

PC Software Bundle Included

The GL820 includes a Windows application for direct capture, measurement, and monitoring of GL820 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.
