AXIS A9910 I/O Relay Expansion Module

Elevate your Axis deployment with the AXIS A9910 I/O Relay Expansion Module, a compact, scalable solution designed to expand digital inputs and relay outputs across enterprise-grade security and automation systems. Built around Axis’ multi-drop technology, the A9910 lets you cascade up to 16 expansion modules to a single AXIS A9210 controller, dramatically increasing your I/O footprint without complicating the network. The result is a high-density, cost-efficient expansion that preserves the integrity and performance of your Axis ecosystem while simplifying installation, maintenance, and future growth. With a total of 128 digital I/Os and 64 relays, this module delivers robust control for doors, sensors, alarms, lighting, actuators, and other I/O devices—all managed through familiar Axis management software and security features. The A9910 is purpose-built for environments ranging from retail to industrial facilities, campuses to warehouses, where dependable, scalable control is essential for automation and safety.

• Scalable, multi-drop I/O expansion: Connect up to 16 AXIS A9910 modules to a single AXIS A9210 controller, achieving a consolidated pool of 128 digital I/Os and 64 relays. This architecture enables rapid growth across large facilities, allowing you to add inputs and outputs as requirements evolve without reconfiguring the core system. The multi-drop design minimizes wiring complexity and cabinet clutter while guaranteeing synchronized operation across all expansion points, delivering predictable performance for security, access control, and automation tasks.
• Power and data over a single PoE cable: The A9910 leverages Power over Ethernet to provide both data connectivity and expansion power via one Ethernet run. This eliminates the need for separate power supplies or additional network drops, simplifying installation and reducing material costs. In practice, you position expansion modules where they’re most effective, confident that a single PoE link keeps them powered and in sync with the AXIS A9210 controller for timely state changes and reliable outputs.
• Cost-effective installation and faster deployment: By removing extra network drops and minimizing wiring, the A9910 enables technicians to deploy I/O expansions quickly. The streamlined topology, coupled with centralized management, means configuration, testing, and commissioning can be completed in a fraction of the time compared with traditional wired expansions. The modular approach also reduces downtime during maintenance or future upgrades, since individual I/O channels or relays can be serviced or replaced without affecting the entire system.
• Seamless Axis ecosystem integration: Designed to work in concert with the AXIS A9210 controller and Axis software, the A9910 supports plug-and-play discovery, straightforward I/O and relay mapping, and synchronized timing across devices. This cohesive integration delivers a unified management experience, enabling real-time monitoring, event-driven automation, and robust interoperability with other Axis devices. You can implement complex automation rules, security workflows, and lighting or environmental controls that respond precisely to sensor inputs and system events.
• Reliable performance for demanding environments: The A9910 is built to deliver consistent, dependable operation in a range of settings, from busy retail floors to manufacturing floors and campus facilities. Its durable design supports long life in mission-critical applications, while Axis’ security framework helps safeguard remote access, data integrity, and system integrity. By centralizing control of numerous I/O points, this expansion module reduces scoping errors, simplifies auditing, and supports scalable, future-proof deployments.
