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.

Features at a glance:

  • 20 to 120 universal analog inputs per chassis; systems to +2,000 channels
