Hello,
I need design one circuit to activate one relay that the coil works at 110Vcd.
I have one previous design with one reed relay that yours contacts activate the coil of the relay at 110Vdc.
In some cases, the reed relay is broken (the contact NormalOpen is internaly cortocircuited). Why protection I can put in this reed relay?
Now, I'm thinking if is posible activate the coil of the 110Vdc with one MOSFET like the IRF820 ( www.datasheetcatalog.org/datasheet/fairchild/IRF820.pdf ). Any sugestion to polarise this transistor?
Thanks!
