PRO-WEI100
Weighing Controller
This intelligent weighing controller ac-
cepts input directly from a 4-wire or a
6-wire strain gauge.
The PRO-WEI100 has a number of ad-
vanced functions designed specifically
for the weighing industry, and is simple
to set up and operate. It also features
output and input isolation, eliminating
the need for any special consideration
when interfacing to analog/serial in-
puts, or PCs/PLCs/HMIs.
