Step 4. Typical Load Cell/Point Input/Output
Measurements (EXC & SIG Outputs)
a. The Weigh Module is designed to sup-
ply 5 VDC excitation to as many as
eight 350 Ohm load cells/points.
b. The expected output from each load
cell/point depends on the mV/V rating
of the load cell/point and the weight.
For example, a 2mV/V load cell/point
will respond with a maximum of 10
mVDC at full system weight capacity,
which includes the weight of the vessel
and the weight of the product as mea
-
sured by the load cell/point. If the load
cell/point weight capacity is rated at
1000 pounds, the load cell/point will be
10 mVDC at 1000 pounds, 7.5 mVDC
at 750 pounds, 5 mVDC at 500 pounds.
