AXIS A9920 I/O-rele-laajennusmoduuli – 8 konfiguroitavaa porttia, RS485, DIN-kiskoasennus

In a busy industrial facility, a security team needs to connect multiple door locks, alarm sensors, and warning lights to their central Axis video management system. The AXIS A9920 I/O Relay Expansion Module provides eight configurable I/O ports that bridge the gap, enabling reliable control and monitoring from one platform. Communicating over RS485 and mounting on a DIN rail or wall, this compact module integrates seamlessly into both new and existing installations.

• Relay type: Form C (NO/NC) with max switching 24 V DC/AC, 1 A
• Digital input voltage range: 0–30 V DC
• Power input: 12–24 V DC, max consumption 10 W
• Communication interface: RS485
• Mounting: DIN rail or wall mount
• Operating temperature: -40°C to 70°C (-40°F to 158°F)
• Operating humidity: 10–100% RH (non-condensing)
• Enclosure rating: IP20, material PC/ABS
• LED indicators: Power, Status, I/O status
• Certifications: CE, FCC, RCM, RoHS, REACH

Why choose it

The A9920 is engineered for flexibility and resilience. Its eight ports can be individually configured as inputs or outputs, adapting to diverse devices such as motion sensors, relays, or dry contacts. With a wide operating temperature range and robust PC/ABS housing, it performs reliably in demanding environments, from cold storage to outdoor enclosures (when properly protected).

Ideal use cases

• Access control: trigger door strikes or monitor door position sensors.
• Industrial monitoring: connect PLC dry contacts, alarm panels, or warning lights.
• Environmental sensing: integrate temperature, humidity, or motion detectors into your Axis system.

Good to know

The A9920 is compatible with Axis network products such as the A1601 Network Door Controller and various Axis cameras. It is designed for indoor use or within protected enclosures. The module includes a DIN rail clip and wall-mount brackets for easy installation. A power supply is not included; use a regulated 12–24 V DC source.
