® ULTRA SLIMPAK II WV438 DC Powered Potentiometer Input Isolating Signal Conditioner High Accuracy Signal Conditioner with an Isolated DC Voltage or Current Output WV438-2000 � Lower Power Requirements with SmartPower � RoHS Compliant � Improved Accuracy � Touch Cal for Best Stability and Accuracy � Bussed Power with Plug-in Power Clips � DIP Switch Configuration � Removable Terminals for Easy Service � Optional E-mail Notification of Alarms Description Enhanced LED Diagnostics The Ultra SlimPak II is an exciting new line of isolating signal Other than when executing the pushbutton calibration routine, conditioners from Action Instruments with greater accuracy and the LEDs blink under the following conditions: better stability than virtually any other signal conditioners on the market today. The Ultra SlimPak II features Smart Power, which GREEN: eliminates wasted power for low loop resistance loads in the Flashes at 2Hz when the input is under range. current output mode.

The WV438 is a potentiometer input signal conditioner supporting RED: 3-wire potentiometers and slidewire devices from 100 ohms to Flashes at 2Hz when the output is under range. 100k ohms. The switch selectable output ranges are 0-10VDC,0- Flashes at 8Hz when the output is over range. 20mA and 4-20mA. All of the output ranges are fully adjustable via pushbutton calibration. The input default range is 0 to 100% An Under Range condition exists when the signal is lower than the of the potentiometer range, but can be adjusted via pushbutton operational low value minus 6.25% of the operational span.

Smart Power A voltage output short circuit may cause an under range condition The Ultra SlimPak II uses Smart Power to control its output supply. (RED blinking at 2Hz rate). A current output open circuit may cause Smart Power automatically adjusts the the voltage to drive the an over range condition (RED blinking at an 8Hz rate). output loop to the required current. A low impedance current loop will subsequently require less voltage than a loop with higher There could be two or more LEDs blinking at the same time, which impedance. Previous designs provided only a single supply at the means the module has more than one error condition. Only when highest voltage required to drive the highest impedance load. all error conditions have been removed, will the LEDs be back to Using Smart Power results in power savings and reduces the normal (Green ON, Red and Yellow Off). operating temperature of the signal conditioner. Configuring Modules Calibration Unless otherwise specified, the factory presets the Model WV438 See the calibration flowchart in Figure 3. The complete calibration as follows: procedure is contained in the Installation & Calibration Instruc- tions document, which is available on our website Input: Potentiometer (www.actionio.com). You can also obtain it by telephoning Action Range: 100 ohms to 100k ohms technical support (703-669-1318). Output: Current Range: 4-20mA Note that Custom Calibration (option C620) is available from the Reverse Out: Off factory (settings MUST be within the units specifications). For a Remote Cal: Off C620, specify the following: 1. Set position 1 of S1 to ON if a WVC16 will be utilized and remote a) Potentiometer Input Range, in percent calibration capability is desired. (for example: Input = 25 to 75% of pot rotation). 2. Set position 2 and 3 of S1 for the desired output type. b) Output Type & Range (for example: 4-20mA). 3. Set position 4 of S1 to ON for reverse output operation. c) Reverse Output Function (ON/OFF). It is also possible to remotely select the setpoints using an Ethernet connection and the optional WVC16 Communications Interface module.
