I want to control the coil of a relay using 6V input to turn on a relay which will activate a 220V device. Is there a relay that works for this application?
2\$\begingroup\$ There certainly exists 220 V relays with 5 V coils. Check the datasheet for them and find out which would cope with 6 V. \$\endgroup\$– winnyApr 19, 2022 at 6:48
\$\begingroup\$ There are plenty of relays with 6V coils. Why not use one of those? \$\endgroup\$– StarCatApr 19, 2022 at 9:48
\$\begingroup\$ Yes, there are many many such relays. \$\endgroup\$– user253751Apr 19, 2022 at 11:09
Check the data sheets for 5V relays. Many will handle slightly higher voltages on the coil.
5V relays capable of switching 220V are very common.
