Axis A9910 is an intelligent I/O relay expansion module designed to scale access control, environmental monitoring, and system responsiveness within larger security ecosystems. With eight supervised I/O ports, four Form C relays, and dedicated Modbus sensor ports, it enables integrators to incorporate external triggers, relays, and sensor data—including temperature and humidity—into a unified IP-based workflow. This device streamlines real-time automation by bridging multiple sensing and switching elements through a single PoE network connection, lowering installation complexity and providing flexibility for facility-wide coverage.

Built on a modular architecture, Axis A9910 supports multi-drop operation, allowing up to 16 modules to be connected to a single Axis A9210 unit. This configuration enables support for up to 128 I/Os and 64 relays from one IP address, minimizing cable runs and reducing system overhead. Its expanded scaling capability ensures reliable performance for large distributed sites such as campuses, logistics centers, and industrial plants while maintaining the efficiency, interoperability, and device visibility expected in enterprise deployments.
