Hi Skip,

Most folks use the 115V relays since the other voltages are DC and obviously 
would take an additional source of power from somewhere.  The contacts in the 
HT-32 and 37 are relay closures so any of the above voltages may be used.

SAFETY FIRST: Put a generous dab of RTV or similar sealant on the relay coil 
terminals, especially if you are using 115V.  I also put a 1 amp fuse in 
series with my relays for additional insurance since I pick up my line voltage from 
a separate source.

73,

John,  W4AWM
