Hardy has always prided itself with the idea
of taking a good product design and
making it better. We believe that it is easier
for the user to learn the new items/features,
than to learn a whole new product. The HI
2151/30WC Weight Controller follows that
line of thinking, just as it has in previous
versions since 1982. We've taken all the
great aspects of the HI 2151/20WC Weight
Controller and added features and improved
functionality to make installation, setup, and
system diagnostics easier than ever before.

PRODUCT DESIGN
The basic design of the HI 2151/30 has
remained the same on all our multipurpose
weight controllers to provide an easy upgrade
path. Hardy understands the difficulties in
replacing a unit and the space limitations on
control panels. That's why we design our
products so you can replace an old unit with a
new one using the same enclosure cutout.

for ease of use in reading weight values as well
as reading menus. A 30 segment bar graph is
standard and can be programmed for various
modes and uses.
FRONT PANEL
The front panel keypad and menus follow the
same pattern. The current menus and features
have been enhanced, but the front panel keys
have remained the same. There is no need to
relearn features and functions of an instrument
when a new one is installed.

SETPOINT CONTROL
The HI 2151/30WC can independently control as
many as eight relays based on either net, gross,
rate-of-change, peak hold or totalized weight
values. Each relay has its own individual preact to
compensate for in-flight material, and deadband
to compensate for relay chatter.
ONE MILLION COUNTS OF RESOLUTION
The HI 2151/30WC has 1,000,000 counts of
resolution yielding better control, accuracy and
recording in weighing applications. This is
25-50 times more than the typical weight
controller resolution. You can tolerate large
dead loads, over sizing of load cells, and still
have an bundance of resolution to work with.
C2® ELECTRONIC CALIBRATION
C2 enables electronic calibration of the weigh
system without test weights. This saves system
start-up costs and aggravation.
WAVERSAVER®
WAVERSAVER eliminates the effects of unwanted
plant vibration on or around the scale by
permitting the weigh module to “see” through
the unwanted vibration signals - as low as
0.25Hz - while yielding a stable actual reading.
SECURE MEMORY MODULEThe rear panel
accessible Secure Memory Module (SMM)
automatically protects and stores critical data. It
allows this data to be physically
transferred from one indicator to another. If a
problem occurs, simply remove the current SMM
and plug it into a new indicator, and your system
will be up in running in minutes.
