Flip-flop - SmartRelay 3 system

The switching time for the relay in the controller can be freely programmed between 0 s and 25 s. If the controller relay needs to be permanently operated, you can activate flip-flop mode.

IMPORTANT

Changing over the relay contact if power fails

The relays in the controller are not bi-stable. Consequently, permanent power is required for switched mode. Relays are no longer supplied with electricity if there is a power outage. In such cases, they switch to a power-off state even without using an identification medium, depending on the original position.

  1. Connect external components in such a way that a power-off state poses no risks.

NOTE

notice

The flip-flop option is not available if the SREL3 ADV system is used with SmartOutput modules.
