There has been some confusion regarding this series of relay and what the input voltage selection should be.

Looking at socket 2966032 as an example you have may notice the input voltage rating is 110VDC/120VAC.

This might drive someone to select the 110/120V input voltage and then never look back. Some folks however have continued on reading and have noticed that on the relay itself there may be a different rating.

This 60V rating on the relay gets most people worried as they do not want to damage it. You do not have to worry. Inside of this base you will find a bridge rectifier and a voltage divider. This delivers the appropriate 60V to the relay sitting within it.
