Product Overview
The NE870 is no ordinary router, it combines the functions of a router and a firewall in one device. It is a DIN-rail mounted device with 11 ports, including 3 10/100/1000 Mbit RJ45 ports and 8 10/100 Mbit RJ45 ports. This configuration provides flexibility in connecting network devices with different speed requirements.
One of its distinctive features is the redundant 24V DC power input. This redundant power design greatly increases the reliability of the router. In industrial environments where continuous operation is critical, the ability to switch to a backup power supply in the event of a primary power failure ensures that the network continues to operate, minimising potential downtime.

Security Partitioning and Network Segmentation
The concept of security partitioning, as described in the IEC 62443 standard, is the foundation of modern industrial network security, and the NE870 plays a key role in implementing this concept. It is able to divide the system into different network areas and security partitions. This partitioning allows different security measures to be applied to different zones depending on their specific risk level and the potential impact of security events.
For example, it can be used to separate the client/server network from the control network. This separation helps to contain potential security threats. If a security breach occurs in the client/server network, it is less likely to propagate to the more critical control network. Similarly, it can be used to isolate different control and security networks, ensuring the integrity of security-related systems. In addition, the NE870 is able to create RNRP tunnel areas between RNRP (Redundant Network Routing Protocol) networks, further enhancing the security and reliability of the network.

Redundant Network Routing Protocol (RNRP) Support
The NE870 revolutionises industrial networks with its support for RNRP, which creates two physically separate networks within an 800xa system. This redundancy is critical to avoid a single point of failure. In a traditional network setup, if a critical network component fails, the entire network can go down. However, with RNRP and the NE870, when one network path fails, data can be automatically re-routed through the redundant network, ensuring the continued flow of data and system uptime.

Product Features and Benefits
1 Redundant Power and Alarm Functions
In addition to redundant power inputs, the NE870 is equipped with alarm functions. This feature immediately notifies the network administrator when power-related problems or other critical failures occur.

With a wide operating voltage range of 16 VDC to 60 VDC, the NE870 is able to adapt to different power conditions in industrial environments. This versatility makes it suitable for a variety of scenarios, whether in a factory with stable power supply or in a remote industrial site where power fluctuations are more frequent.
3 Stable Installation and Monitoring Capability
The back of the NE870 is equipped with a cast DIN clip for stable mounting on DIN rails. This is a standard mounting method for many industrial control panels, ensuring easy and stable installation.
On the monitoring side, the router has digital I/O capability. This feature allows it to interact with other devices in the industrial network to monitor network status, such as network traffic conditions, status of connected devices, and potential network bottlenecks.
4 Easy Management and Configuration
The NE870 is equipped with a console port that supports management through a command line interface (CLI). This gives network administrators granular control over the router’s settings for advanced configuration and troubleshooting. It also features a USB port that simplifies the process of saving and loading system configurations. This is especially useful when deploying multiple NE870 routers in a network, or when changing router configurations during maintenance and system upgrades.
