The AXIS A9920 is an I/O and relay expansion module for access control and security systems that need to cover more doors, gates, or monitored points than a single controller can handle on its own. It works with the AXIS A9210 and other Axis door controllers, adding 16 supervised inputs and outputs along with 16 Form C relay outputs to the system. Multiple A9920 modules can be connected together, which means a single IP connection is able to manage up to 128 I/Os and 64 relays in total. That scale makes it a good match for facilities with a lot of access points to monitor, such as elevator banks and data centers. Installation stays flexible, and the module is designed to integrate with access control systems built by other manufacturers rather than require a full hardware replacement.
