Applying the supply voltage to the relay coil will close the contact 1 between terminals 8-9 and the contact 2 between terminals 11-12. This state is indicated by a green LED. After a power failure, the both contacts open.
The “LED” version of the relay is equipped with a contact designed to cooperate with receivers with high starting current, such as: LED fluorescent lamps, ESL fluorescent lamps, electronic transformers, discharge lamps, etc.
