What is the purpose of the expansion ports on the Alarm Panel Pro?

Understanding the Expansion Ports on the Konnected Pro Board.

The Konnected's Interface Module is used only when connecting in parallel to a traditional alarm panel. The interface module bypasses the zone terminals on the Pro. It adds additional circuitry to tap into a legacy alarm panel zone (instead of a bare open/closed sensor). The Interface Module is not useful in the case of retrofitting or converting sensors to work directly with Home Assistant.
