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 WV468 has both voltage and current input ranges. Eight AC
voltage input ranges (50mV, 150mV, 500mV, 5V, 20V, 50V, 150V &
250V) are DIP switch selectable. Each of these ranges has at least 95%
zero and span adjustment. Two AC current input ranges (20mA and
100mA) are also available. Outputs include 0-10V, 0-20mA and 420mA. The WV468 also supports reverse output mode.
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.

Enhanced LED Diagnostics
Other than when executing the pushbutton calibration routine,
the LEDs blink under the following conditions:
GREEN:
Flashes at 2Hz when the input is under range.
Flashes at 8Hz when the input is over range.
RED:
Flashes at 2Hz when the output is under range.
Flashes at 8Hz when the output is over range.
An Under Range condition exists when the signal is lower than the
operational low value minus 6.25% of the operational span. An
Over Range condition exists when the signal is higher than the
operational high value plus 6.25% of the operational span.
A voltage output short circuit may cause an under range condition
(RED blinking at 2Hz rate). A current output open circuit may cause
an over range condition (RED blinking at an 8Hz rate).
There could be two or more LEDs blinking at the same time, which
means the module has more than one error condition. Only when
all error conditions have been removed, will the LEDs be back to
normal (Green ON, Red and Yellow Off).

Configuring Modules
Unless otherwise specified, the factory presets the Model WV468
as follows:
Input: mVAC
Range: 0-500mV
Output: DC Current
Range: 4-20mA
Reverse Out: Off
Remote Cal: Off
Calibration
See the calibration flowchart in Figure 3. The complete calibration
procedure is contained in the Installation & Calibration Instructions document, which is available on our website
(www.actionio.com). You can also obtain it by telephoning Action
technical support (
Note that Custom Calibration (option C620) is available from the
factory (settings MUST be within the units specifications). For a
C620, specify the following:
1. For other ranges, refer to the SWITCH SETTINGS table.
Reconfigure switches S1 and S2 for the desired input type and range.
2. Set position 1 of S1 to ON if a WVC16 will be utilized and remote
calibration capability is desired.
3. Set position 2 and 3 of S1 for the desired output type.
4. Set position 4 of S1 to ON for reverse output operation.
5. Set positions 5-8 of S1 and positions 1 & 4 of S2 for the desired
input range.
It is also possible to remotely select the setpoints using an Ethernet
connection and the optional WVC16 WebView Communications
Interface module.
