1, 2, or 3 Channels @ 0.5 VA, 1.5 VA or 3.0 VA

Synchros 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 Digital-to-Synchro simulator is used to convert digital angle/velocity commands to corresponding Synchro/Resolver AC signals.

A wide variety of D/S 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. By eliminating the need for external transformers and operating with lower AC reference frequencies, these solid-state designs offer huge space savings.

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.

 

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.
