It’s written in the relay “4098-12VDC-1C”“28VDC 125VAC 3A”
My 1st question it’s, is the realy sure for 220VAC 1A?
The 2nd one it’s. On the PCB R6 it’s doesn’t, there it’s a wire, and if you look the photo on the web there is a resistance. what are the diferences?
It’s surely NOT safe to use the relay contact for high voltage. The contact burning by switching will destroy the contact with as result burning out of the relay.
My advise dont’ use it for 230 v.
