You would NOT connect a 72xx (Analogue control box) directly to a k83 (Digital Control Box)


The 763xx Yes - BLUE = actually 4 "equavalent" blue wires for up to 4 signal aspects
The 764xx No.


The 76xxx has its own decoder and does not need a 6083(0) k83

No, Not connected together


You may use some additional controller device that causes the Signal to do something at the same time as it changes the Turnout .


Analogue
Assuming your 76xxx means a 763xx generation signal, then it could be used in analogue mode and you could have a wire from a 727x control box to switch both it and the turnout.

Digital
For digital control of your 24611, you will need a decoder - here a k83 could be used as the go-between
The 76xxx is quite capable, as it has an internal decoder as standard.

A digital controller would then be able to send commands to each device . In most cases these days a single route can be configured to do the two operations with the single press of a button.



If it is automation you are after then
Analogue
The 727x analogue control switch can be replaced (augmented) with switch of a circuit/contact track from the layout

Digital
A similar Circuit/Contact track, as above, could send its trigger to the controller who in turn would activate the route(s).
This does require an additional - S88/6088(x) - interface box for the controller to receive the trigger through.
