I have a door drive 28-year-old. Works with your Empfängerset like new again.
Receiver part was defective, replacement would have cost 102 euros plus 2x remote controls a 48.50 Euro (original manufacturer).
The Raliasausgänge I had to part with 230 V and solder a bridge, my power is 34 volts
But has not been a problem.
For the price, the 10 minutes worth work.
I hope the run continues this product in their range.
