Product Description
µp-based signal conditioner,
for current, voltage, temper-
ature, resistance, rate, fre-
quency, speed and period
measurements. Measuring
ranges and functions easily
programmable from the PC
by means of optional Usc-
Soft software available on
request. UscSoft includes
programming, display and
min-max functions. Condi-
tioner housing for DIN-rail
mounting with front protec-
tion degree: IP 20. All dis-
playing and programming
data are referred to UscSoft.
