Frequently asked questions
How do I drive this relay from a microcontroller?
A microcontroller pin cannot supply the 12 V coil directly. Switch the coil through a transistor or MOSFET powered from 12 V, and place a flyback diode across the coil.
What loads can it switch?
The contact is rated for 5 A, with a maximum switching voltage of 30 VDC or 277 VAC according to the listing. Keep loads within these ratings.
