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
WV428 supports B, C, E, J, K,
N, R, S & T thermocouples
that are DIP switch selectable.
The WV428 also supports a millivolt
range of -20 to +80mVDC. The
input accuracy of the WV428
is 0.05% with a CJC error of
£ 1 C. Both voltage and
current have an input accuracy
of 0.015% of full scale. Outputs
include 0-10V, 0-20mA and 4-20mA.
The WV428 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.
