Description
CAUTION: These instruments are designed to be used ONLY
with the MurphyLink
TM
†
MurphyLink TM PowerView products.
The PowerView Analog Gages (PVA) are a series of intelligent gages
designed to display easy-to-read information transmitted by the PowerView.
The PVA gages communicate with the PowerView via a single RS485 twist-
®†
ed pair MODBUS RTU serial link. The gages can be daisy-chained using
quick-connect harnesses with watertight connectors.
The PVA gages also include features such as a smooth stepper motor opera-
tion for the 270° sweep pointer, an environmentally sealed case with two
Deutsch DT style connectors molded into the casing, and green LED back
lighting. They are available for standard 2-1/16 in. (52 mm) and 3-3/8 in. (86
mm) diameter hole sizes. In addition their plastic cases incorporate a "D"
shape allowing panel cutouts that eliminate gage rotation during installation.
The PowerView Audible Alarm (PVAA) alerts operators to fault conditions
via piezoelectric alarm and relay contacts. It also has a temporary silencer
button that silences the audible tone for 2 minutes on alarms and 30 seconds
on shutdown conditions.
All PowerView Gages can be powered by 12 or 24 VDC systems.
