Description
CAUTION: These instruments are designed to be used ONLY with the MurphyLinkTM† PowerView module or other approved MurphyLinkTM† PowerView products.
The PowerView Analog Gages (PVA) are a series of intelligent gages designed to display
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
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.
