Powerful Monitoring
The GL500-2-1 can monitor two 4-20 mA sensors (0-5 volt inputs are available as a factory option) and features a scalable digital input that accepts switch closure signals and pulses from various external devices. The logger provides switched power to the sensors based on the programmable sample interval and sensor warm up time settings.
Two- and three wire sensors can be quickly connected to the datalogger’s internal terminal strip and calibrated via the included Global Logger II software. The GL500S-2-1 can be accessed through dial-out to an optional remote modem (GL500-Mod) attached to the serial communication port.
Smart Software
The GL500-2-1 includes Global Logger II Windowsâ„¢ and Windowsâ„¢-CE PDA software, which allow for easy setup, calibration, upload, and transfer to a spreadsheet program.
