The Graphtec GL260 Compact 10-Channel Voltage and Thermocouple Datalogger can save high-capacity measurement data directly in the internal memory or SD memory card. With a 4.3 inch color display, it features 10 isolated analog input channels, 4 discrete inputs, and 4 discrete outputs with extremely flexible triggering conditions. The discrete inputs can be configured as a group to be either logic inputs or pulse inputs. When configured for pulse, each of the four channels can be configured to measure frequency or to count. The four discrete outputs are alarms that can be triggered by a variety of easily-defined analog and pulse/discrete input channel conditions. The analog input channels may each be configured to measure a direct-connected voltage in the range of 20 mV to 100 V full scale across 12 ranges, or for a direct-connected thermocouple of any type to measure temperature. Each of the GL260’s analog input channels is electrically isolated from other channels and from power ground allowing off-ground measurements using shunts, as well as powered or grounded thermocouples.

The most powerful feature of the GL260 is its triggering flexibility. Data recording can be independently started or stopped as a function of analog and pulse/discrete signal level (single or windowed), alarm, date and time, and day-of-the-week. Configure triggers to operate only once or to automatically repeat. With the ability to adapt to virtually any desired trigger condition, the GL260 can operate unattended for long periods of time.

The GL260 Datalogger operates entirely stand-alone or via connection to a PC. Connect to a PC with a standard USB or optional wireless connection. The PC-side software configures, acquires, displays, and records digitized information for storage directly to the hard disk drive. Retrieve acquired data for review or analysis after recording with the ability to export to Microsoft Excel. The GL260 has 4 GB of non-volatile memory embedded inside the instrument. The instrument supplies an external SD card slot for additional storage if needed.
