Synchro / Resolver Simulation (D/S) (D/R)

 

Modules D/S and D/R

Modules D/S and D/R are NAI’s latest generation Synchro/Resolver Simulation Modules. These programmable, isolated output modules used on our multifunction embedded boards and SBCs are unique, solid-state designs that operate down to 47 Hz.

Synchros and Resolvers are transformer-type voltage/current transducers that convert a shaft or other rotating device's angular position and/or velocity to a multi-wire AC electrical signal. Both deliver signals proportional to the Sine and/or Cosine of the shaft angle. A Resolver-to-Digital or a Synchro-to-Digital simulator is used to convert digital angle/velocity commands to corresponding Synchro/Resolver AC signals.

A wide variety of D/S and D/R modules are available to cover the range of excitation voltages/frequency, include extensive field-parameter programmability, and provide a full operating envelope choice for simulating virtually any type Synchro or Resolver. By eliminating the need for external transformers and operating with lower AC reference frequencies, these solid-state designs offer huge space savings.

There are three types of D/S and D/R modules:

  • 3-Channel Modules:

These high-density modules have a lower power output drive (0.5 VA per channel, max.). The lower power output drive is ideal for driving solid-state input instruments, gauges, and Synchro Booster Amplifiers (SBAs).

  • 2-Channel Modules:

The 2-channel modules have a standard (1.5 VA per channel, max.).

  • Single-Channel Modules:

The single-channel modules have a high-power output drive capability (3 VA per channel, max.).

All D/S modules feature a wrap-around self-test capability and most platforms support an optional, programmable AC excitation supply. In addition to state-of-the-art technologies and design algorithms, the modules include many other useful application features such as reference voltage and frequency measurement, reference loss detection, and paired channel, two-speed operation.
