Description
The Ultra SlimPak II is an exciting
new line of isolating signal
conditioners from Action Instruments
with greater accuracy and better
stability than virtually any
other signal conditioners on
the market today. The Ultra
SlimPak II features Smart Power,
which eliminates wasted power
for low loop resistance loads
in the current output mode.
The
WV408 has both voltage and current
input ranges. Four voltage input
ranges ( 150mV, 1.5V, 15V and
150V) are DIP switch selectable.
Each of these ranges has at
least 95% zero and span adjustment,
which, for example, would allow
you to set a 0-20mV user range
on the 150mV full scale range.
Two current input ranges ( 2.5mA
and 25mA) are also DIP switch
selectable. "Sigma-Delta"
conversion produces an effective
resolution of 15 bits. Both
voltage and current have input
accuracies of 0.015% of full
scale. Outputs include 0-10V,
0-20mA and 4-20mA. The WV408
also supports reverse output.
The WV408 is recognized for
use in Class 1, Division 2,
Groups A, B, C, D hazardous
locations.

Smart
Power
The Ultra SlimPak II uses Smart
Power to control its output
supply. Smart Power automatically
adjusts the the voltage to drive
the output loop to the required
current. A low impedance current
loop will subsequently require
less voltage than a loop with
higher impedance. Previous designs
provided only a single supply
at the highest voltage required
to drive the highest impedance
load. Using Smart Power results
in power savings and reduces
the operating temperature of
the signal conditioner.
