Controller Expansion Modules
An access control expansion board adds inputs and outputs to an existing controller, letting one panel handle extra alarm points, relays or doors without replacing it. The Armatura AHEB-0808 suits integrators growing an existing installation.

How to choose an expansion module
Expansion boards are tied to a controller platform, so compatibility comes before anything else.
- Host panel: confirm on the datasheet that your controller model and firmware support the board.
- Input and output count: list every sensor, alarm contact and relay you need now, then leave headroom for later.
- Communication bus: check how the board connects to the panel and the maximum cable distance allowed.
- Relay rating: make sure relay contacts suit the voltage and current of the devices they will switch.
- Power: include the board's own consumption when sizing the power supply.
Compare host options under controllers and panels. For a sized proposal on a larger site, use the request a quote form with your door and point count.
