The DM650VI is a battery powered process signal indicator. The instrument accepts a signal within the ranges of +/-50 V or +/-50 mA signal and displays the process value in the appropriate engineering units on a 6-digit LCD display..  As it has a low energy electronic design, 1 alarm relay and 5000 point data logging are built in, along with on screen messaging to alert a user to take action.  Datalogging can be accessed through the built in USB port and free software application.  Visit the software page to download the USB Loglink software.
