Switching 125VDC 0.5amps

We have the need to switch 125VDC 0.5amps worst case. Most likely we will only switch when the power supply is off, but as a precaution we should probably account for the scenario (software bug) where we would switch while this DC voltage and current are present.
Do any of your RS232 products have specs that this could work? I saw the relay data sheets but most specify max switching voltage in AC not DC.

Our 10 amp relays here have a maximum switching DC voltage of 125VDC:

Any of these relay controllers can be purchased with these 10 amp relays installed and an RS232 interface:

If you have any other questions please let us know.

Thank you,
