Problems with the NI2503

I want to connect 120 Vdc to an open relay in this mux. Normally when the relay is closed, it is just allowed to connect 60 Vdc. Will it be a problem if I connect 120 Vdc to an open relay?

Dear Sir,

Thanks for using the Developer Zone.

I strongly suggest you not to connect any signal having voltage above 60 VDC to the relays even being an opened relay. It has to do with the isolation from the circuitry of the board.
