Front panel digital instruments

Front-panel digital instruments
The wide range of front-panel digital instruments starts with single-phase mono-function
measurement devices for measuring voltage and current.
The range is composed by a voltmeter for a.c./d.c. voltage monitoring, and one ammeter
for a.c. Ammeters measure in indirect insertion thanks to measuring
accessories, like current transformer for a.c.
VLMD P The full-scale value is programmable by the user, according to the current flow on the
primary windings.

Front-panel digital instruments with alarm relay
The range is widened by one additional devices with extended features: one ammeters that
trip the internal relay to signal an alarm condition if the measured parameter exceeds or falls
AMTD-_ P below a programmable threshold. The measured maximum and minimum peak values are
stored in the non-volatile instrument’s memory.
The contact type is NO, so that the contact is open when the instrument is powered off,
but it is possible to obtain positive safety operation setting, directly on the instrument,
the NC relay contact type.
The instrument with relay can be used to signal the exceeding or the fall below a certain
threshold, but not for both functions simultaneously.
