The Define Instruments Zen data logger is ideal for connecting to a mixture of analog and digital sensors. The inputs are all individually isolated and EMC hardened, making it fit for the most demanding industrial environments. It can be set up as an analog multiplexer, utilizing the on-board dual analog outputs, or as an alarm and control station, using the 16 built-in setpoints. These setpoints can trigger up to 16 relay contacts if connected to the optional ZEN-RIO I/O expansion (sold separately).

A free download of the WorkBench software is available; use it in conjunction with the Zen data logger to plot graphs and visualize your data for a better understanding of your results. You can also export your data to CSV format for further analysis using Excel.
