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
