5.15 DRY CONTACT RELAYS
The RPV311 has 4 electromechanical signaling relays. Each relay has one dry contact, as shown in Figure
134.
The first relay contact is normally closed and it opens when the unit goes into operation and it is not
configurable by the user.
The other three contacts are normally open and can be individually configured using the Web Interface. For
information about relays output configuration, see Chapter 17.
