That module is made for 24V logic. So yes, you can just hook up your voltage straight to the inputs. It was provide a 30kOhm resistance to ground (input impedence in the spec). It is generally not a good idea to count on a digital input to complete a circuit. The digital input should be more of a sense.

Thank you for your quick reply, as you said the 9425 will be used as a sense input and will not be used to complete the circuit.
