15. Appendix 1. Connecting external controller to smartDEN Opener
relays
Controlling barriers (or other devices with built-in controller) using smartDEN Opener's dry
output contact is easy. Just attach relay to Main Controlled Device and control barriers. An
example of hardware connection is given on
Figure 15.1 and configuration is given on Figure
15.2. In this example is assumed that barrier is opened on short circuit on the dry contact digital
input and closed on open circuit. Controlling is made by OPEN and CLOSE buttons (commands)
and could be controlled by web server, HTTP XML and JSON requests, MQTT commands and RF
Remote Controller.
Figure 15.1. Hardware Connection to smartDEN Opener
In our example Relay1 is controlling the barrier. Relay 1 is attached to Main Controlled Device.
So when click OPEN button (send OPEN command) the barrier will open and when click CLOSE
(send CLOSE command) the barrier will close. Additional features like Attach DI Protection Sensor
or timer "auto close" function could be used too for fully automation (see
10.4. Main Controlled
Device Page ).
