I am using axuillary relays to supply voltage to my 12Vdc power relays. The spec for the auxillary relay is 5Vdc, 170mW 130ohm. If I am not mistaken, this means the relay current is just under 40mA. As the relays are non-latching they will be on for long periods of time. I am thinlking of using 2 ou…
