[Boatanchors] Determining Rated Voltages on DowKey Relays

Tue, 2 Dec 2003 22:52:35 -0600

Bill,

The Dow Key relays were typically stamped with the voltage rating on the
coil cover. If there is no marking there, you will probably need to test it
at low voltages first. There might be measurable differences in the
resistances of the coil windings for 110VAC vs the 12 or 24 Vdc coils, but I
have never compared them.

Good luck & 73,
