Connecting Sensors and Activators Using an IA Relay Board
If you want to connect additional dry sensors and/or one activator to the CVG, you can do so by connecting an
Intelligent Appliance IA 3126-2 relay board to the unit. Up to 16 additional dry sensors and 16 additional activators
can then be connected to the unit through the relay board. Sensor and activator events from devices connected to an
IA relay board can be seen in SerVision client applications and activators can be turned on and off via these
applications. However, the sensors and activators cannot be configured using the CVG’s configuration utility.
NOTE: Alternatively, you can connect additional sensors using an ADAM module, as explained under
Connecting Sensors Using an ADAM Module, page 12. Sensors that are connected through an ADAM
module can be configured using the CVG’s configuration utility.

For information about connecting sensors and activators to the IA 3126-2 relay board, and about connecting the
relay board to a power source, please consult the relay-board’s documentation.
