The turntable motor is controlled by a loc decoder designed for DC motor types. The function outputs, front and back light, are used to activate the turntable. (yellow wires)

Setup

The center contacts of all turntable rail-clips should be electricaly isolated, or as I did removed, and connected to s88 compatible feedback module. (Those modules accepting also the "red-wire" as input signal.) They should be declared in the plan.xml as the posfb's int the turntable tracks.

Those feedbacks are activated by the lips of the turntable bridge center contact rail.

The turntable has 48 steps of 7.5°. The connected tracks are numbered counter-clockwise and track 0 is the 0° of the first quadrant. This is the way the RocGui renders the turntable, and this item can not be rotated.

For DC turntables the position sensors can be made with Reed relais and at one side of the bridge a magnet.
