Description

The ERES104 provides a direct interface to two Synchro/Resolver/Inductosyn/LVDT channels on the compact PC/104 form factor. 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 11.8 VRMS or 90 VRMS configurations.

The onboard programmable sine wave oscillator reference outputs a 5 - 7Vrms excitation signal with a programmable frequency range of 400 to 1600Hz.

This compact board is capable if interfacing to LVDT-sensors and Inductosyn scales with dedicated preamplifier and signal conditioning boards. Please contact the factory for more information on dedicated preamplifier and signal conditioning boards for the ERES104.

You may use the ERES104 to interface to geared Synchros or Resolvers; connect the high gear channel to one input and the low gear channel to the other. The code conversion can then be performed using a software routine.

A direct I/O mapped 16-bit wide host interface is used to address the board. Sensor data can be acquired in two ways; either by polling the channels or by an interrupt driven scheme where an interrupt is generated upon an LSB change on either channel. Both of the RD-converters have their own independent jumper selectable host interrupts.
