Introduction

The Veeder-Root brand Series 7990 is the best value in a low cost, versatile indicator
for industrial applications.  Highly flexible, it can be programmed at installation to
operate as a totalizer, rate indicator  (Model 799008-201 only), or elapsed time meter.
With this unique functionality, it can be used to totalize parts production, keep track
of machine hours, indicate process times, or show production rate.  Input scaling
accommodates a variety of signal sources with the ability to readout in meaningful
engineering units.  Use two or three of them and have matching control panel
instrumentation for count, speed, and time.  Standardize them throughout your
plant, and reduce inventory by stocking just one indicator instead of several.

Many convenience features are included, such as adhesive labels preprinted with
popular engineering unit identifiers, security locks for reset and programming, and
accessory snap-on adaptor modules.  The adaptor modules allow screw-terminal wire
connection and/or accommodation of high-voltage input signals for timing or
counting applications.  Accessory
panel adapters, available with or
without a locking key reset, allow
easy mounting and retrofit to
older and larger mechanical,
electrical or electronic products.
