AXIS A9910 I/O Relay Expansion Module for Door Controllers & Access Control

Product SKU: AXIS A9910

Product Overview

The AXIS A9910 I/O Relay Expansion Module is a flexible access control and security expansion module designed to add more inputs, outputs, relays and sensor connectivity to compatible Axis systems. It features 8 configurable I/O ports with supervised input capability, 4 Form C relays, 4 Modbus sensor ports and multi-drop technology for scalable expansion. Up to 16 AXIS A9910 modules can be connected to one compatible Axis host device, enabling up to 128 I/Os and 64 relays using a single IP connection. It is ideal for door control, alarm integration, lift control, environmental monitoring, access control expansion, secure rooms, plant rooms, warehouses, schools, offices and commercial security systems.

Why Choose the AXIS A9910 I/O Relay Expansion Module

The AXIS A9910 is ideal for organisations that need to expand an Axis access control or I/O system without adding unnecessary network drops. Multi-drop technology allows multiple expansion modules to connect to one compatible Axis host device, helping reduce cabling complexity and installation cost. Its 8 configurable I/Os can support supervised inputs for tamper-aware monitoring, while 4 Form C relays provide flexible control of connected equipment. The Modbus sensor ports also allow integration with environmental sensors such as temperature and humidity sensors, making it useful for access control, automation, monitoring and facility management workflows.

Key Capabilities

Key Features

• 8 Configurable I/O Ports: The AXIS A9910 includes 8 configurable input/output ports that can be used for sensors, contacts, alarm devices, request-to-exit devices, status monitoring or external equipment control. This helps expand system flexibility beyond the built-in I/O of compatible Axis controllers.

• Supervised Input Support: Supervised input capability allows inputs to detect more than a basic open or closed state when wired with the correct end-of-line resistor design. This can help identify tampering, wiring faults or abnormal input conditions in higher-security installations.

• 4 Form C Relays: Four Form C relays provide flexible wet or dry relay control for connected equipment. This is useful for locks, gates, lifts, lights, sirens, alarms, automation systems and other devices that need to be switched or triggered by access control events.

• 4 Modbus Sensor Ports: The module includes 4 Modbus sensor ports for integrating environmental sensors such as temperature and humidity sensors. This is valuable for server rooms, storage rooms, plant areas and other environments where environmental conditions need to be monitored alongside security events.

• Up to 16 Modules Per Host Device: Multi-drop technology allows up to 16 AXIS A9910 modules to connect to one compatible Axis host device. This helps build larger systems with substantial I/O and relay capacity while reducing the need for additional IP connections or extra network cabling.

• Up to 128 I/Os and 64 Relays: When fully expanded, one compatible host device can support up to 128 I/Os and 64 relays using connected AXIS A9910 modules. This makes the module suitable for complex access control, automation, alarm and facility monitoring projects.

• Compatible Axis Host Devices: The AXIS A9910 is designed for use with compatible Axis devices such as AXIS A9210 Network I/O Relay Module and selected Axis door controllers. This makes it a useful accessory for expanding Axis access control and I/O-based security workflows.

• Encrypted Communication Setup: An encryption key is used when adding AXIS A9910 modules to supported Axis devices, helping protect communication between the module and host. This is important in access control and security installations where relay and I/O events must be protected.

• Wall or DIN Rail Mounting: Flexible mounting support allows the module to be installed on a wall or DIN rail depending on the cabinet, enclosure or equipment layout. This makes it practical for structured access control cabinets, electrical rooms and professional security installations.

• Cost-Efficient Expansion: By adding multiple I/O and relay points through one compatible host device, the AXIS A9910 helps reduce network cabling, simplify project design and lower installation effort compared with deploying separate networked modules for every expansion point.

Specifications Summary

Ideal Use Cases

• Access Control Expansion – Suitable for adding more inputs and relays to compatible Axis door controller systems where additional locks, sensors or external devices need to be monitored or controlled.
• Lift and Gate Control – Useful for relay-based control of lifts, gates, barriers and secure entry points where multiple outputs are required as part of the access control workflow.
• Alarm and Sensor Integration – Practical for connecting door contacts, request-to-exit devices, PIR sensors, glass break detectors, alarm contacts and other security inputs into one Axis-managed system.
• Environmental Monitoring – Ideal for integrating Modbus temperature or humidity sensors in server rooms, plant rooms, storage areas, laboratories and facilities where environmental conditions matter.
• Large Commercial Security Systems – Suitable for offices, schools, warehouses, retail stores, healthcare facilities and industrial sites requiring scalable relay and I/O expansion without adding unnecessary network cabling.

Understanding I/O and Relay Expansion

The AXIS A9910 is designed to expand the number of physical inputs, outputs and relays available to a compatible Axis access control or I/O system. Rather than adding a separate network device for every group of inputs or relays, installers can use multi-drop expansion to connect up to 16 AXIS A9910 modules to one compatible host. This provides a scalable way to connect door contacts, request-to-exit devices, alarms, sensors, locks, lights, gates and environmental sensors through one organised system architecture.

Tip:
Use the AXIS A9910 when a compatible Axis access control or I/O system needs more relays, monitored inputs or environmental sensor connections. Confirm the compatible host device, power supply, relay load, input supervision design, Modbus sensor requirements, cabinet space and expansion module count before installation.
