APPLICATION
The VisiPak V508 and V509 digital
process indicators are useful in any
application requiring a digital
readout from a DC input.
DESCRIPTION
Models V508 and V509 DC input
indicators offer selectable 3-1/2 and
4-1/2 digit display, selectable
decimal points and wide-ranging
zero and span display adjustability.
Available options include a transmitter output which provides a 0-1VDC
(Option T) or 4-20mA (Option G)
output corresponding to the input
span. The V508 and V509 operate
directly from 120VAC line power.
INPUT SELECTION
V508 DC, wide-ranging display,
span adjustable from 100
counts to ±1999 counts,
zero adjustable over entire
range, field- selectable
decimal point position and
3-½/4-½ digit display.
V509 Two-wire Loop (4-20mA),
integral 24V two-wire
xmtr. supply, provides
power to, and displays the
output of, a two-wire transmitter; display adjustability
similar to model 508.
See Standard Input Tables for
ranges. Consult Factory for other
ranges.
OPTIONS/ACCESSORIES
T 0-1V Transmitter Output
G 4-20mA transmitter output
U Urethane coating,
(environmental protection).

CALIBRATION
Zero and span adjustments are
located behind the lens. Zero is
adjusted for the desired minimum
display with the input at its minimum. Span is adjusted for the
desired maximum display with the
input at its maximum. Repeat
adjustments as needed.
Units with Option T or G have
separate transmitter zero and span
adjustments through the back of the
case. Transmitter zero and span
adjustment is similar to the display
adjustment.

INSTALLATION
Mechanical: Indicators are installed
from the front of the panel into a
1.65 x 3.60" (42 x 91mm) cutout.
Cam-locks secure the indicator
from behind the panel. To install,
remove the front lens and slide the
indicator into the panel cutout. Turn
the screws on either side of the
display CCW until the cams clear
the panel thickness. Rotate the
screws CW to swing the cam-locks
into position and secure the
indicator.
Electrical: All connections are
made to the rear panel using
standard barrier-terminal strip
connectors.
