OT: IP Rated DC Current Switch w/ Dry Contact

Off topic, but you people here usually have pretty good suggestions.

Title kind of says it, anyone know of a DC current switch that has a decent IP rating for outdoors and dry contact output does not require a power supply? Looking to monitor/log when power is lost on a 72VDC power supply.

When you say IP rated what level of protection all will have an IP rating from 0 to IP68 It is unlikely there is such a relay but what is stopping you putting it into an IP68 box ?.
Here is the link to RS types.
