Hey All,

I am working on controlling a entry gate to our facility and its in a kind of unorthadox way. I have a WiFi gate controller from a company called DoorKing. The way that their controller works is, when you toggle open or closed on the app (or the schedule programmed by the user commands open or closed), it just connects the two output leads via dry contacts. So no voltage output, just contacts connecting momentarly. The Gate opener control board knows the gate position and via board relays N.O. or N.C. and will control the signal.

In order for the gate to open and stay open during business hours (which is the end goal) I need constant 24v to the open control on the gate opener control board. I got a Latching relay to allow me to continuously supply the voltage that is needed. The problem is, that I need to be able to change the polarity on the WiFi controller contacts so that it will reset the latching relay and release the Voltage to allow the gate to revert back to its normal operation.

Does anyone have any idea how to reverse the polarity on a control like this?

 

Is there just one set of contacts on the output of the WiFi controller or is there two sets of contacts. one set for open and one set for close ? Is the latching relay a single coil version that requires one plarity to latch it on and the reverse polarity to latch it off ?
Could you not use a two coil latching relay where pulsing one coil latches it on and pulsing the other latches it off ?
Posting the manuals on the WiFi controller, the gate controller and the latching relay would be helpful.

One set of contacts.

I have attached the Wiring Diagram for the WiFi Module, the Circuit Board of the Opener, and the Relay Diagram
