Description
The V565 is a loop-powered digital
process indicator which derives
its power entirely from the
4-20mA or 10-50mA signal being
measured. No local power is
required at the point of measurement.
The
3-1/2 digit, 0.8” high
Liquid Crystal Display (LCD)
provides clear visibility up
to a distance of 30 feet, and
can be easily calibrated to
the required range. Zero and
fullscale can be set anywhere
between -1999 and 1999. Span
can be from 0 to 3998 counts
(100 count minimum span).
The
V565 provides linear and square
root operation, permitting direct
flow readings from differential
pressure origins (e.g., orifice
plates). The V565 is also equipped
with selectable direct/reverse
display gain. Reverse operation
provides a decreasing count
with an increasing input. A
trailing, dummy, zero allows
display readings to ±19990.
The decimal point position is
switch selectable and can be
independently set to any of
four positions (1.9.9.9.).

Application
The V565 is useful in any application
requiring a wide-ranging 3?
digit display from a 4-20mA
or 10-50mA current source. The
V565's standard NEMA 4X housing
enables indoor or outdoor installation
with protection from sleet,
corrosion, moisture, chemicals,
and even hose directed water
or severe condensation. The
V565 is ideal for displaying
process variables in local and
remote areas where line power
is not available or impractical.
The
V565 is entity approved by FM
for intrinsically safe operation
in Class I, II, and III, Division
1 & 2 hazardous locations
when installed per manufacturer's
drawing 790-0029-00.
The
V565 is also intrinsically safe
per CSA for operation with the
following housings when installed
per manufacturers drawing 790-0025-00:
panel housing: Class I, Groups
A, B, C and D; conduit housing:
(Opt C) Class I, Groups A, B,
C and D. Class II, Groups E,
F and G. Class III; EP housing:
Class I, Groups C and D. Class
II, Groups E, F and G.t.
