1 Introduction
Product Overview
The ERES35105 provides a direct interface to two Synchro/Resolver/LVDT channels on the compact PC/104 form factor with a stackable PCI
Express bus. Both sensor input channels are independently configurable with jumpers. An onboard solid state Scott-T circuitry provides a
precision conversion from Synchro to Resolver signals. Onboard precision thin-film resistor divider networks for 2.0, 11.8 or 90.0 V
RMS
configurations.
The onboard programmable sine wave oscillator reference outputs a 0 - 7V
RMS
excitation signal with a programmable frequency range of 0 Hz
to 10 kHz.
