It was originally planned for the garage door but it has many more applications. The system was to control two relays to change, supports limit switches and be compatible with radioline (optional).
The system has:
  • two outputs (left, right)
  • three inputs (left, right, stop) controlled by buttons or radioline
  • two inputs for limit switches NO (left, right)
  • two inputs for limit switches NC (left, right)
  • stabilized voltage outputs: 24v, 12v, 5v
  • three info diodes (left, right, stop)
The radioline doesn't need to have three channels, two channels are enough, because the STOP function is supported by activation of two inputs (left, right) at once.
The system works with 24W (24V – 1A) transformer. It's closed in box in the garage.
