Using TReX with vintage Selyns?

Hello, Has anybody interfaced a TReX to vintage selsyn (aka synchro) error signals?
We are restoring the remotely controlled gun turret on a WWII bomber.

Since we don’t have all the obsolete electronics, we are wanting to interface a vintage, classical 57.5 VAC selsyn error signal to the analog input of a TReX motor controller. The error mag and phase signal (wrt the 115 VAC, 400 Hz supply) is. VError = 57.5 cos( Theta_error -90deg) VAC

Any body seen circuit for this already designed?

Hello.

We do not know of anyone who has done that or any conversion circuit to recommend, and high voltage AC signals will definitely not interface directly with the TReX.
