Fluke 2680 Series Data Acquisition Systems

Brand: Fluke Corporation

Standalone or networked precision multi-channel DAQ

The Fluke 2680 Series data acquisition systems combine the best of lab precision with the rugged flexibility required in rapidly changing industrial applications. 

Whether you choose the 2680A Data Acquisition System with high-speed 10/100BastT Ethernet network support or the 2686A Data Logging System, you can seamlessly expand your system any time from 20 to more than 2,000 channels, just by adding modules and chassis.

Both models feature six slots in each chassis that you can fill with modules as needed to meet your application requirements. 

Five slots in each chassis are available for any combination of 2680 Series 20-channel analog input modules. The sixth slot is reserved for a 2680 Series digital I/O relay module to add control capabilities to your system. 

If you don't need the sixth slot for control, you can plug in an additional analog input module, increasing your channel count to 120 in a single chassis.

You can also link multiple 120-channel systems together seamlessly for the widest possible view of your data. And with TCP/IP connectivity you can connect to existing LANs to distribute information wherever it needs to go. 

Whether you need speed and throughput, isolated precision, or digital I/O and relays, the Fluke 2680 Series can scale up to thousands of channels to meet your needs.

The Fluke 2680 Series offers the choice of networked data acquisition, stand-alone data logging, or a combination of both. Choose from two basic chassis models:

2680A Data Acquisition System chassis

The Fluke 2680A Data Acquisition System is the choice for multi-channel applications requiring reliable Ethernet communications. It features a front-end style data acquisition system that communicates and distributes data anywhere you need it to go. The 10BaseT and 100BaseT communications interface makes it compatible with both older and newer network installations.

2686A Data Logging System chassis

The Fluke 2686A Data Logging System writes data to a memory card for easy retrieval and storage, making it ideal for remote locations and mobile or non-computer assisted data logging applications.

The system comes with a 16 MB ATA memory card and supports ATA flash memory cards of up to 1 GB to provide the memory capacity you need. 

The 2686A is easily configured for stand-alone data logging operations by simply selecting a preset configuration from the memory card. 

It can also be used in networks in tandem with the 2680A to provide the extra data security of a memory card.

Scale your system to meet your needs

With the Fluke 2680A and the 2686A, you can seamlessly expand your system from 20 to more than 2,000 channels just by adding modules and chassis.

Both models feature six slots in each chassis that you can fill with modules as needed to meet your application requirements. Five slots in each chassis are available for any combination of 20-channel analog input modules. 

The sixth slot is also available for a digital I/O relay module to add control capabilities to your system. 

If you don't need the sixth slot for control, you can plug in an additional analog input module, increasing your input channel count to 120 in one chassis.

You can also link multiple 120-channel systems together seamlessly for the widest possible view of your data. And, with TCP/IP connectivity, you can connect to existing LANs to distribute information wherever it needs to go.

Whether you need speed and throughput, isolated precision, or digital I/O and relays, the Fluke 2680 Series can scale up to thousands of channels to meet your needs. 

Buy just the modules you need in the combinations you need and expand your system as your requirements grow.
