There are also less expensive (and UL listed, to boot) protection units
available these days. With the increased prevalence of remote
control/monitoring, ethernet, etc. the commercial market has lots of
transient protection devices out there. I haven't looked in a few
months, but the last time I checked, an 8 line protector for 24VDC
control signals was in the $50 range.. nice weathertight box with cable
gland entries, etc.
