Operation principle

Fast action relay :

* minimum control input time : 30 ms
* minimum recycling time : 800 ms
* permanent eneggization of the coil without consequence on the relay's reliability.

Contacts rating :

* 0,25 A / 125 VDC / L/R 50 ms = 1000 operations
* 0,15 A / 220 VDC / L/R 50 ms = 1000 operations.

FONCTION


Versions

The 2448 relay us a specifically designed "fast action relay", equipped with 4 x 5 A CO contacts. The basic design is made of :

* One 1804 relay of 4 x 5A CO contacts (qualified EDF HN45S25 cl. 2a)

* Electronic components giving fast peak up response <= 5 ms of the 4 NO contacts.
