cRIO-9805

Земля NI cRIO-9805 является 4-port Ethernet switch expansion module designed for CompactRIO and industrial embedded systems that require additional Ethernet ports and 802.1AS time synchronization. It expands the networking capability of CompactRIO controllers by adding internally switched Ethernet ports with deterministic synchronization support.

Unlike the cRIO-9803, which is used for SSD storage expansion, the cRIO-9805 is focused on industrial Ethernet networking, TSN synchronization, and distributed CompactRIO system integration.

Типичные применения включают:

• TSN-enabled CompactRIO networks
• Distributed measurement systems
• Industrial Ethernet expansion
• Multi-controller synchronization
• Smart manufacturing networks
• Machine monitoring systems
• Remote data acquisition
• Промышленные испытательные системы

Ethernet and TSN Architecture

The cRIO-9805 provides:

• 4 Ethernet ports
• Internally switched architecture
• 10 / 100 / 1000 Mbps auto-negotiated communication
• 1000BASE-TX full-duplex support
• Maximum cable distance of 100 м на сегмент
• До 15 hops per line topology

The module supports IEEE 802.1AS synchronization over 1000BASE-TX full-duplex Ethernet. Standard synchronization accuracy is listed as less than 1 μs, and optimized configuration can reach less than 100 ns.

This makes the cRIO-9805 useful when engineers need multiple CompactRIO or Ethernet-based devices to share a synchronized network timing reference.

Network Protocol and Configuration Support

The cRIO-9805 supports common industrial network configurations, including:

• TCP/IP
• UDP
• DHCP
• DHCP + link-local
• Static IP
• Link-local IP configuration

This flexibility allows engineers to use the module in both factory networks and isolated test systems. For distributed CompactRIO deployments, the internally switched architecture helps reduce the need for additional external Ethernet switches.

Прочный промышленный дизайн

The cRIO-9805 is built for industrial environments and distributed embedded systems. Its rugged specifications include:

• Случайная вибрация: 5 g RMS, 10 Hz to 500 Hz
• Sinusoidal vibration: 5 g, 10 Hz to 500 Hz
• Operating shock: 30 g, 11 ms half sine
• Operating shock: 50 g, 3 ms half sine
• 18 shocks at 6 orientations

NI’s getting-started documentation also notes mounting guidance for high shock and vibration environments, including direct mounting to a flat rigid surface.

Прикладные варианты использования

Distributed CompactRIO Networks

The cRIO-9805 is useful when multiple CompactRIO controllers, industrial controllers, or synchronized measurement nodes need to communicate over a deterministic Ethernet network.

TSN-Based Synchronization

For applications requiring 802.1AS time-based synchronization, NI recommends the cRIO-9805 Ethernet Switch Expansion Module.

Machine Monitoring Systems

In machine condition monitoring, the module can help connect synchronized acquisition nodes across different parts of a machine or production line.

Industrial Test Systems

The module is suitable for test benches where multiple Ethernet-connected controllers or acquisition devices must operate with shared timing coordination.
