Interface to a gate controller
Posted: Sat Aug 18, 2018 1:35 pm
I have a new gate controller(GiBiDi BA230) and would like to interface it to my home automation system. The challenge of the moment is to detect the gate state. There is a controller output that provides 24vdc according to the following pattern
I have tried using a 1054 but so far without any success. At first it kept measuring 50Hz (I am in France) so I figured that was AC line leakage and I ran the output signal through a diode bridge. That got rid of the 50Hz signal, but did not produce anything useful. My next try will be to use the relay between the controller and the 1054 and switch 5v. Even then, I am concerned about how quickly the 1054 will actually detect changes, and if it will differentiate between steady on and off states.
But, I was wondering if anyone has any other ideas on how to approach this project.
Ideas?
- Gate State - Voltage
Closed - 0vdc
Opening - 24vdc pulsed at 1Hz
Open - 24vdc (steady)
Closing - 24vdc pulsed at 2Hz
