1552 +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.
1553 +
1554 +To detect a Dry Contact, you can supply a power source to one pin of the Dry Contact. Below is a reference circuit diagram.
