Access Unit 2.0 nero 2N

The 2N Access Unit 2.0 Black is a compact access control module designed for integration into building entry systems and electronic door control. It supports Ethernet LAN data rates of 10/100 Mbit/s and operates from a DC supply in the range of 8–12 V, with typical power consumption of 600 mA and a maximum DC current capability of 2 A. The unit's small footprint (107 mm × 28 mm × 130 mm) allows installation in confined spaces while providing network connectivity and reliable power handling for peripheral devices.

Advantages

The 2N Access Unit 2.0 Black combines a compact form factor with standard Ethernet connectivity and stable DC operation, making it suitable for retrofit and new installations. Its moderate power consumption and higher maximum current output enable connection of additional low-voltage peripherals. The device's small dimensions simplify mounting in cabinets, frames, or behind panels without requiring extensive space. Ethernet 10/100 support ensures compatibility with existing network infrastructure and predictable data transfer for access control management.

Suitable for

• Integration with electronic door controllers and intercom units
• Retrofit projects in residential and small commercial buildings
• Installation where limited enclosure space is available
• Systems requiring standard 10/100 Mbit/s Ethernet connectivity

How to use

Mount the Access Unit 2.0 Black in a suitable enclosure or behind the device panel, ensuring adequate ventilation and access to the network cable and DC power source. Connect an Ethernet cable to a 10/100 Mbit/s network port and supply DC power within the specified 8–12 V range, observing polarity. Verify that connected peripherals draw current within the 2 A maximum DC current capability. Configure network and access control settings according to the system controller or management software documentation to enable communication and functionality within the access control system.

Recommendations

Use a regulated DC power supply that provides stable voltage within the 8–12 V range and sufficient current headroom above typical consumption. Place the unit where the Ethernet connection is protected from physical damage and interference. For installations with multiple peripherals, verify cumulative current draw to avoid exceeding the 2 A limit. Follow local installation standards and the system integrator’s guidelines when integrating the unit into access control setups.
