The 2280 Series family of data loggers combines high measurement accuracy, exceptional configuration flexibility, and computer-like power without requiring the user to write software. This family, composed of the 2285B Data Logger and the more powerful 2286A Data Logging System, offers solutions for demanding data acquisition and reporting problems. The 2286A Data Logging System features an MS-DOS compatible microfloppy drive for data and program storage. The disk can be taken from the 2286A, inserted directly into a PC, and the data files (stored in DIF format) imported into Lotus 1-2-3™, Excel, or other spreadsheets. The 2286A is expandable from a simple 20-channel data logger to a distributed 1500-point data acquisition system. For applications that do not require all the power or expansion capabilities of the 2286A Data Logging System, the 2285B Data Logger is a more economical solution. Expandable up to 100 channels, the 2285B accepts most 228X I/O options. The 2280 Series displays collected data, the results of calculations, or outputs can be viewed on its bright, 40-character display, or logged on the wide format 40-column internal printer. Adding further recording flexibility are two communication ports which can be configured with optional RS-232C or IEEE-488 interfaces. For Demanding Environments Applications that require more input or output points than can be housed in the mainframe are satisfied by using the 2281A Extender Chassis. Any input or output options housed in an extender chassis have an operating range of -20°C to +70°C. Another standard feature is full operation from 12V dc power, making the 2280 Series a natural for mobile data acquisition.
