--From above DI ports circuit, we can see that active the photocoupler will need to have a voltage difference between DI+ and DI- port. While the Dry Contact sensor is a passive component which can't provide this voltage difference.
++From DI port circuit above, you can see that activating the photocoupler requires a voltage difference between the DI+ and DI- ports. However, the Dry Contact sensor is a passive component and cannot provide this voltage difference.
--To detect a Dry Contact, we can provide a power source to one pin of the Dry Contact. Below is a reference connection.
