- Role
- Control interface
Control & power
- Control type
- OSDP over RS-485
- Power supply
- 12–24 V DC; maximum 240 mA at 12 V or 130 mA at 24 V for the base board
OSDP over RS-485 from an access controller that supports this module and its input/output commands. Relay contacts switch an external circuit; they are not the module control input.
A suitable smart controller can expose supported functions to Matter. The control type alone does not confirm electrical compatibility or actual position feedback.

Selection & installation notes
- Documented as an Azure system expansion; verify controller and software support before using another ecosystem.
- Ethernet and PoE+ depend on the ordered variant; not included in every base unit.
- No native Matter; requires a separate controller integration.
