FONCTION

Versions

The 1848 relay is a specially designed fast action relay equipped with 4 x 5 A CO contacts. The basic design is made of :

- One 1804 relay with 4 x 5A CO contacts (qualified EDF HS45S25 cl. 2a)

- Electronic components giving fast peak up response of 5 ms or less of the 4 NO contacts.

Contacts rating  :

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