Series ED
Oscillator/Demodulator
The Series ED Oscillator/Demodulator is designed to simplify installation for 35mm DIN Rail and Panel Mount applications. It provides DC-in/DC-out operation for AC LVDTs and is internally regulated for additional stability of the output signal. Optimized for 3 kHz or 7kHz performance. A variety of voltage outputs are available as well as 4-20 mA; all with zero offset and span adjustment.
Key Features
- Works with 5 and 6 wire LVDTs
- Internally Regulated
- DC Voltage Output
- Small Size and Low Cost

* Oscillator output voltage adjusted via span adjustment potentiometer.
* Oscillator output current operates into a 100 ohm load with less than 0.25% Distortion.
** Output voltage and or current determined when using transducer whose sensitivity is 0.500 V/v +/- 10% at both ends of stroke Adjusted via the span control potentiometer.
*** Output temperature coefficient for voltage output din rail series +/- (.01% Of output +/- .00025V/deg.F)
*** Output temperature coefficient for current output din rail series +/- (.008% Of lvdt stroke + .00122Ma)
**** Output polarity, when connected as shown the output voltage will become more positive as the core moves towards the lead end. Polarity may be reversed by interchanging connections to pins # 7 and 9
