Three relay modes

1. Normal Each of the four relays can be independently switched on and off.

2. Pulse (Pulse) The relay automatically switches off after a set time (e.g. 1 second), which is ideal for controlling entrance or garage doors.

3. Interlock (Interlock) Only one of the four relays can be switched on at a time. Activating one automatically deactivates the others, which is ideal for controlling motors or roller shutters (prevents simultaneous 'up' and 'down' signals).

The configuration of the relay operation mode is carried out from the eWeLink application.
