Specifications  
Description  
Power Supply Input Voltage: 12/24V (8-32VDC min. & max. voltage).  
CAUTION: These instruments are designed to be used ONLY  
with the MurphyLinkTM PowerView module or other approved  
Power Supply Operating Current: (@ 14 VDC) =  
PVA20, PVA35: 28 mA minimum; 52 mA maximum.  
PVAA20: 19 mA minimum; 46 mA maximum.  
MurphyLinkTMPowerView products.  
Backlight Maximum Current (not applicable to PVAA20): 24 mA.  
Input: RS485 MODBUS® RTU data.  
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.  
Output: Analog Readout.  
Relay Rated Load (PVAA20): 0.5 A, 125 VAC; 1 A, 24 VDC.  
Relay Maximum Switching Capacity (PVAA20): 62.5 VA, 30W.  
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.  
External Audible Alarm Output (PVAA20): 28 VDC, 30 mA max. (cur-  
rent sink).  
Temporary Silence Button (PVAA20): Charge transfer technology.  
Operating Temperature: -40° to 185°F (-40° to 85°C).  
The PowerView Audible Alarm (PVAA) alerts operators to fault conditions Storage Temperature: -76° to 185°F (-60° to 85°C).  
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.  
Dial: White numerals over black background.  
Indicating Pointer: Stepper motor operation with 270° sweep.  
Gage Accuracy: PVA20: Better than ±1.0% of scale.  
All PowerView Gages can be powered by 12 or 24 VDC systems.  
PVA35: Better than ±2% of scale.

WARNING: Disconnect battery negative cable before wiring or service. Devices containing solid state components can be damaged or caused to  
malfunction when used in systems which incorporate inductive loads (e.g. relays, solenoids, etc.) that can generate voltage spikes. To reduce the  
potential for this type of damage, install a fly back or clamping diode across all inductive loads. Use Murphy diode package 65-00-0343 or equivalent.  
A typical diode is 1N4005 and is readily available from commercial sources. Failures of this type are not covered by our Limited Warranty.
