Acceptable design bad design

I am working on a trouble shooting device that will monitor for the absence or presence of voltage in control circuits. The input of the device is a rely that is held in by the circuit under test. That could be 120 volts 24 volts or what ever voltage. You just change the relay to the appropriate voltage. The input relay is a double pole relay one pole will have various voltage and the other pole will 120 volts the operating voltage of the trouble shooting device. The questions is,is it acceptable design to have low and high on opposite POLES of the same ice cube relay.
Thanks LC

I'm hardly a low voltage electrician.

First, where's the road map to go by?

I can only relate to your situation in the simpliest of principles, the A/C.
An A/C will have low voltage on one side, that pull in the contacts to let
240 run across the contacts.

I can't think where x voltage is on one side and 120V is on a second pole sitting
on the same side!

I guess it could happen, but I thought that ice cubes only went up to 48V.

But In fact I'm bumping the keyboard here... :001_huh:
