Graphtec GL7000 central unit with USB and Ethernet interface

Modular acquisition system for measurement data

The modular data logger consists of a central unit, several input modules and is expandable with a display unit and an additional memory module (SDD). Up to 10 modules can be connected to a central unit.

The GL7000 has RAM memory for 2 million samples and built-in flash memory of 2 GB. Alternatively, the data logger can also store measured values on an external SD card (up to 32 GB) or in the SSD memory module. Automatic data backup possible.

Data recording can be started and stopped manually on the device, via an external trigger or time-controlled. The individually adjustable alarm output can be used to monitor the individual measurement channels and offers in addition to min or max. Configuration and data recording are also possible directly on the PC via a USB interface.

Depending on the structure, the logger has up to 112 input channels.
