Description
ABB NE870 3BSE080239R1
Product Introduction
The ABB NE870 3BSE080239R1 is an industrial Ethernet router and firewall designed for ABB control-system network architectures, particularly System 800xA environments. Unlike a conventional unmanaged Ethernet switch, the NE870 provides Layer 3 routing, integrated firewall functions, and ABB’s Redundant Network Routing Protocol (RNRP). ABB specifies the unit for separating client/server networks from control networks, separating control and safety networks, and establishing RNRP network areas.
The ABB NE870 3BSE080239R1 provides 11 copper Ethernet interfaces: eight 10/100 Mbps RJ-45 ports and three 10/100/1000 Mbps RJ-45 ports. There are no SFP interfaces on this model. The router supports RNRP, allowing physically separate network paths to be incorporated into an ABB control-system architecture. ABB also provides integrated firewall functionality for traffic filtering between network areas.
The ABB NE870 3BSE080239R1 is designed for DIN-rail installation and accepts 16–60 VDC. ABB specifies redundant power capability, digital I/O for monitoring, a USB Micro-B console/management interface, and status LEDs. The unit is rated IP40 and operates from −40 to +70°C, with storage from −50 to +85°C. Its compact 134 × 100 × 122 mm housing is intended for installation inside industrial control cabinets rather than exposed outdoor installation.

Main Features and Engineering Considerations
1. Layer 3 Industrial Routing
The ABB 3BSE080239R1 is a router rather than a simple Ethernet switch. Its Layer 3 routing capability allows different IP network areas to be separated and interconnected under controlled routing rules. This is particularly relevant to DCS architectures where control, server, safety, and service networks should not all exist as one flat Ethernet segment.
2. Integrated Firewall
The combines routing with firewall functionality. ABB describes its use for security zoning and separation of different control-system network areas. The actual firewall configuration remains a site-engineering issue: replacement hardware does not automatically reproduce the existing routing rules, access policies, network addresses, or security configuration.
3. RNRP Network Redundancy
RNRP is one of the defining functions of the . ABB describes RNRP as enabling two physically separate networks within 800xA architectures, allowing communication to continue through the alternate network path when a network disturbance occurs.
This means that replacing an is not simply a matter of connecting Ethernet cables to an equivalent router. The RNRP topology, port assignments, IP configuration, routing behavior, and paired network architecture should all be documented before replacement.
4. Mixed-Speed Copper Ethernet
The router provides eight 10/100 Mbps ports and three 10/100/1000 Mbps ports. This mixed-port arrangement should be considered when reproducing an existing cabinet network. A cable that physically fits an RJ-45 port does not mean every port has identical bandwidth or intended network function.
5. Redundant DC Power
ABB specifies a 16–60 VDC operating range and redundant power supply capability. The wide input range makes the suitable for common industrial DC control supplies, but the actual cabinet power architecture should still be checked before replacement.
6. DIN-Rail Installation
The rear of the unit incorporates a DIN-rail mounting arrangement. The specified dimensions are 134 × 100 × 122 mm, with a published weight of approximately 1.5 kg. Cabinet clearance should be checked around the Ethernet connectors and power terminals, not only against the housing dimensions.
7. Environmental Range
ABB specifies −40 to +70°C operation and −50 to +85°C storage. The IP40 enclosure is appropriate for protected control-cabinet installation but should not be interpreted as an outdoor or washdown rating.
Application Scenarios
ABB System 800xA Networks
The is designed for ABB control-system network architectures and is documented within the System 800xA network product family.
Control and Server Network Separation
The router can be used to separate client/server networks from control networks while maintaining controlled communication between network areas.
Control and Safety Network Segmentation
ABB specifically identifies network separation between different control and safety networks as an application for the .
RNRP Redundant Networks
The can form part of an RNRP architecture using two physically separate network paths.
Industrial Security Zoning
The integrated firewall and routing functions support network segmentation consistent with industrial security-zone architectures.
Legacy and Existing ABB Network Maintenance
The exact 3BSE080239R1 article number is important when maintaining an existing ABB network because the related NE871 uses article number 3BSE080240R1 and has a different port configuration.
Engineer’s Guide: Field Pitfalls
Do not substitute NE871 automatically. NE871 has only three 10/100/1000 Mbps copper ports, whereas has eight 10/100 Mbps ports plus three gigabit ports.
Back up the network configuration. IP addresses, routing rules, firewall rules, RNRP configuration, and management settings are more important than the physical router itself.
Record every Ethernet connection. The 11 ports are not simply interchangeable from a system-engineering perspective.
Verify RNRP topology. A network may contain physically separate redundant paths whose operation depends on the router configuration.
Check the power architecture. The accepts 16–60 VDC, but the existing installation may use dual independent DC feeds.
Do not treat IP40 as field-exposed protection. The unit is intended for protected industrial installation.
Check firmware/configuration compatibility. ABB’s current network selector reports NEOS version information separately from the hardware article number. The installed system’s approved software baseline should be checked before changing a network device.
Do not assume an ordinary industrial router is a functional replacement. RNRP and ABB-specific 800xA network integration are key parts of the ‘s role.
Verify the USB/console access method. The USB Micro-B interface is documented as the console interface and may be required during commissioning or recovery.
Check the firewall policy before putting the replacement online. A factory-default router connected to a live DCS network should not be treated as an already-configured replacement.

It is designed for DIN-rail mounting.
Does have SFP fiber ports?
No. The ABB specification lists no Ethernet SFP ports for . Its Ethernet interfaces are copper RJ-45 connections.
What is the difference between and NE871?
Both are ABB industrial routers with RNRP and firewall functions, but their Ethernet-port configurations differ. provides eight 10/100 Mbps ports plus three 10/100/1000 Mbps ports, while NE871 provides three 10/100/1000 Mbps ports. Their ABB article numbers are also different.
Procurement Note
For an ABB 3BSE080239R1 replacement, specify the complete article number, not simply “.”
Before purchasing, verify:
- Exact article number: 3BSE080239R1.
- Eight 10/100 Mbps Ethernet ports.
- Three 10/100/1000 Mbps Ethernet ports.
- Absence or presence of SFP requirements.
- RNRP network topology.
- Firewall and routing configuration backup.
- Current IP addressing.
- Dual DC power arrangement.
- ABB 800xA network architecture.
- Firmware/NEOS baseline.
- DIN-rail cabinet clearance.
- Existing network-security configuration.
The key procurement risk is configuration loss rather than simple hardware mismatch. The is a managed router/firewall with RNRP functionality, so a replacement that powers up successfully can still fail to restore the control network if its routing, firewall, redundancy, and port configuration are not reproduced correctly.
ABB currently identifies 3BSE080239R1 as the article number and continues to document the model within its network hardware selector.
