Hi there,
I install CCTV systems and have had a request to install a NVR recorder, with the ability to open/close an electronic gate. Close to the NVR, there is a switch that the operator presses when on site, one button to open, one to close and an emergency stop. I have linked to a diagram showing all of this below.
I believe that the gate relay uses a 24v circuit. There are 4 outputs on the NVR that I can switch off and on, they are labelled 1, G, 2, G, 3, G, 4, G I understand that they are volt free, dry relays.
The button uses an NO circuit to open, another to close the gate, plus a NC as the emergency stop.
I am unsure if I need some other type of relay to go inbetween the NVR and the switch to achieve the above, perhaps someone could recommend something? It would be really appreciated!
