Relay can send metering data to and receive information from select Inter Plug-in Communication (“IPC”) compatible iZotope plug-ins, including: Insight 2, Tonal Balance Control, Neutron, Neutron EQ plug-in, and Neutron Visual Mixer and Nectar.

It is automatically included for free when you install Nectar 3. You update it directly in the Splice application, just like all other plugins on the Rent to Own program.
