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.
