2680 Series Data Acquisition Systems Technical Data The Fluke 2680A Data Acquisition System and Fluke 2686A Data Logging System (the 2680 Series) are the newest in a long line of Fluke precision data acquisition products. Both systems feature: • 120-channel capacity chassis designed for small- and largescale precision data acquisition applications. • User-scalability from 20 to 120 universal analog input channels; can include digital input/output and alarm contact outputs in a single chassis. • Ethernet TCP/IP protocol with network interface for 10/100 BaseT. • Powerful HMI development software and OPC server software available. Key system features: • 20 to 120 universal analog inputs per chassis; systems to +2,000 channels • Stand-alone data logger operation with the 2686A • Large scalable LAN systems using the 2680A with 10BaseT/100BaseT • Two types of Universal Input Modules: high-isolation precision modules or fast scan modules, with 16- to 18-bit resolution • Throughput of more than 3,000 channels per-second per chassis with 2680A-FAI modules • Superior thermocouple measurement accuracy (J, K, R, S, T, N, L, U, C, B) • 20 digital I/O and 8 form C, 1 Amp relay output modules for direct control of equipment • Up to 300V input isolation, 1600V transient overvoltage protection (2680A-PAI) • Universal input conditioning for any input, on any channel, in any combination (Vdc, Vac, Ohms, frequency, RTD, thermocouple, thermistor or current) • ATA flash memory card for stand-alone operation—from 16 MB to 1 GB (2686A only) • Multiple power sources: 100 to 240 V and 9 V to 45 V dc • Includes Fluke DAQ Software which: • Controls all 2680 Series functions and data files • Provides real-time and historical trending • Also communicates with and controls Fluke 2640A, 2645A NetDAQ products Fluke 2680 Series: A powerful choice 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 multichannel 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.
