50 SERIES DATALOGGER SYSTEM The 50 Series combines the features of a traditional datalogger with many measurement functions and datalogging modes. The use of application-specific integrated circuits and surface-mount technology to reduce circuitry size makes the 50 Series a very portable datalogger. Model 52A. Model 52A Datalogger is configurable, half-rack-sized, with 1 to 4 installable measurement modules (Option 50-1 or 50-2), and up to 4 Digital I/O boards (Option 50-14). Each measurement module provides independent A/D (DMM-type) or counter type measurements. The system allows each measurement module to service up to 64 multiplexed inputs, giving a maximum total measurement channel count of 260 (256 multiplexer channels plus 4 front panel channels). Also, with 4 Option 50-13 Digital I/O boards, the 52A may access up to 32 bits of digital inputs, 32 bits of digital outputs, and four 8-bit-resolution analog outputs. The 52A offers stand-alone operation, with the potential to store over 100,000 readings internally. The 52A can also function as a measurement front end for a computer. It is easily connected to any personal computer for data downloading. The 52A may also be controlled remotely (set up, programmed, started, stopped) by a computer or dumb terminal. Multiplexer and Printer. The 52A has two companion products; the Model 53 Multiplexer/Expansion Chassis, and the Model 54 Printer/Plotter, The Model 53 accepts either 53-1 or 53-2 multiplexers. The Model 54 printer has extensive plotting capability.
