Mix and Match up to 10 units different input/output modules	Up to 10 input/output modules of the same kind can be attached to one main unit

Touch panel system Intuitive operation by using touch panel. Also able to operate with cursor keys with the same feeling as the midi LOGGER GL serie.

The detachable display module allows both stand-alone and embedded system configurations
	Measurement settings and signal measurement can both be done without a PC by attaching the display module. The display module can be moved to different locations for remote operation by connecting it to the main module with a LAN cable*, it also can be embedded into the system. The module can stile be operated by the PC even when the display module is connected.

Large easy-to-read 5.7-inch high-definition display Utilizes a bright clear TFT color LCD monitor. Makes it easy to read data in waveform or digital form and to check measurement parameter settings.

The GL7000 is a modular data acquisition instrument that provides an array of configuration options to allow virtually any industrial measurement. Its most basic form consists of the GL7000 processing module and an attached Alarm module (included). The addition of one or more analog and/or discrete modules completes the configuration and allows the GL7000 to acquire data either to its own internal memory or directly to an Ethernet- or USB-connected PC.

When used as a stand-alone instrument the GL7000 can record data to fast, non-volatile RAM (up to 2 Msamples), 4 GB built-in flash memory, SD memory card ( up to 32GB), An optional solid state disk module (SSD) is available that provides up to 128 GB of fast, non-volatile storage space with a maximum file size of 4 GB.

Sample rate and measurement range is defined by the optional analog modules that may be attached to the GL7000 processing unit. Some modules support a sample interval as low as one sample every microsecond and a full scale range of 100V. Others support various special measurement functions like direct-connected Thermocouples and RTDs for temperature measurements. Another module supports discrete and pulsed-discrete inputs allowing state, count, and rotational rate measurements to be acquired along with analog data. As many as ten modules may be connected to a GL7000 processing unit.
A complete list of modules is included in below datasheet.

The optional touch-screen display is detachable and allows local data logger and data acquisition configuration without a PC. The display also provides real time feedback during data recording in the form of a multi-channel, real time graphical display of acquired data, alarm states, and much more. The display may be attached to the GL7000 processor, or tethered up to 10 meters away from the processor using a standard CAT-5 cable.

The GL7000 data acquisition and data logging characteristics may also be configured by a remote PC connected to the instrument's Ethernet port, or locally using its USB port. Software is provided to allow real time data acquisition, stream-to-disk, playback, and export to other applications like Excel.

Like other data logger and data acquisition products in the GL line, the GL7000 provides extreme triggering flexibility that allows it to adapt to virtually any recording application. Of course, data acquisition operations to a connected PC, or data logging operations in a stand-alone mode may be manually started and stopped. When enabled, the triggering features of the GL7000 automate this process and allow recording processes to be initiated and terminated based upon signal level settings, date and time, and external events. 0-100% pre-trigger information may be stored when recording to the instrument's built-in 2,000,000 storage points (per analog module) RAM memory. Trigger level conditions include settings for edge triggering, level-only tests, and dual level settings to allow inside/outside window triggering. Recording can also be initiated and terminated as Boolean functions of multiple input channels using logical AND/OR combinations.

Finally, up to ten alarm outputs are available with the included Alarm Module. Alarms can be initiated based upon any trigger condition previously described, as well as upon TC burnout, and alarm states may be held or automatically reset when the alarm condition no longer exists.

The GL7000 is a total solution instrument that is easily expanded to meet growing measurement requirements for high- and lowspeed applications, and stand-alone or PC-connected implementations.
