Axis A9910 Λευκό Χρώμα θήκης Λευκό Ονομαστική τάση εισόδου 12 24 V

The AXIS A9910 White is an I/O expansion module designed to increase system flexibility for surveillance and security installations. With a nominal input voltage of 12–24 V and an operational temperature range from -40 to 55 °C, the unit is suitable for a variety of environments. Using multi-drop technology, the module connects to an AXIS A9210 device and allows expansion of inputs, outputs and relays without requiring additional network cabling.

Advantages

The module supports connection of up to 16 expansion units to a single AXIS A9210, enabling up to 128 I/Os and 64 relays over one PoE link. This reduces installation cost and complexity by eliminating the need for extra network cable drops. Built-in Modbus sensor ports allow straightforward integration of environmental sensors such as temperature and humidity sensors. The white housing and robust design provide reliable operation across a wide temperature range.

Suitable for

• Expanding I/O capacity for security and surveillance systems
• Integrating environmental sensors (temperature, humidity) via Modbus
• Installations where cabling minimization and cost-efficiency are required

How to use

Connect the AXIS A9910 White to an AXIS A9210 device using the supported multi-drop PoE connection. Multiple A9910 modules can be daisy-chained—up to 16 units—to increase total I/O and relay capacity while using a single network/PoE feed. Attach required sensors to the Modbus sensor ports for environmental monitoring and wire inputs/outputs and relays according to your system design and local electrical regulations. Ensure the nominal input voltage is within 12–24 V and mount the unit in an environment that falls within the specified temperature range.

Recommendations

For cost-effective installations, plan module placement to minimize cable runs and use the multi-drop capability to reduce the number of network drops. Verify compatibility with the AXIS A9210 and follow AXIS wiring and installation guidelines when connecting Modbus sensors and relay circuits.
