Description

Product Overview

NE870 3BSE080239R1 is an 11‑port DIN‑rail mount industrial Layer3 router with integrated firewall, developed for ABB Ability™ System 800xA DCS platforms. Optimised for RNRP (Redundant Network Routing Protocol), it undertakes network segmentation, security isolation and redundant routing duties for process‑control systems. It separates office IT networks, client‑server zones and real‑time control networks in compliance with IEC 62443 industrial cybersecurity requirements, preventing cross‑zone security threats from affecting critical DCS control traffic.

Modern power‑plant and process‑plant DCS deployments require physical dual‑network redundancy plus zone‑based access control. Conventional commercial routers lack support for the proprietary RNRP redundancy protocol used by 800xA, risking single‑points‑of‑failure during network faults. NE870 3BSE080239R1 resolves this challenge: dual independent power inputs eliminate power‑related outages, built‑in firewall filters unauthorised traffic, and native RNRP support enables seamless switch‑over between two physically isolated control networks without human intervention. USB and CLI console ports simplify configuration backup, restore and on‑site commissioning diagnostics for plant maintenance teams.

Key Features and Advantages

native RNRP redundant routing: NE870 3BSE080239R1 is purpose‑built for System 800xA. RNRP delivers automatic fail‑over across two separate physical control networks, removing single‑points‑of‑failure for DCS communication links.

integrated industrial firewall: Enables security‑zone partitioning between corporate IT, HMI client network and real‑time DCS control domain. Filters illegal cross‑zone access and mitigates cybersecurity risks for critical process control infrastructure.

redundant wide‑range DC power: Dual power inputs accept 16‑60 V DC. If one power feed fails, the second input sustains continuous router operation, critical for non‑stop running of power‑generation and chemical‑plant DCS systems.

NE870 3BSE080239R1

multiple diagnostic options: Front‑panel status LEDs, alarm digital‑output terminals, CLI console and USB configuration port. Operators can export configuration files for backup and rapid spare‑unit restoration during outage maintenance.

DIN‑rail compact aluminium housing: Rugged enclosure fits standard control cabinet DIN‑rails. Designed for harsh plant‑side cabinet environments with temperature fluctuation, electromagnetic interference and vibration typical of power and process sites.

seamless 800xA ecosystem integration: Pre‑validated for System 800xA; no custom firmware modification required. It works together with 800xA controllers, workstations and other NE‑series network hardware to build complete redundant control‑system networks.

Application Fields

NE870 3BSE080239R1 is deployed inside DCS control cabinets of thermal‑power plants, combined‑cycle power stations, petrochemical refineries, pulp‑and‑paper mills and large water‑treatment facilities running ABB System 800xA.

In power‑generation sites, it performs network isolation between plant office LAN, HMI client/server segment and controller real‑time control network. It implements RNRP dual‑network routing to guarantee uninterrupted communication between AC 800M controllers and operator workstations during single‑network failure events.

For petrochemical and chemical process units, NE870 3BSE080239R1 divides DCS into multiple security zones as per IEC 62443 standards. It restricts unauthorised cross‑zone data flow, protects critical safety‑related control domains, and sends hardware‑fault alarm signals to plant monitoring systems via digital alarm I/O terminals.

It is widely used in DCS modernisation and spare‑part replacement projects. Existing 800xA installations adopt this router to upgrade network security and redundancy without replacing core controllers, extending asset service life.

Installation and Maintenance

pre‑installation preparation: Before powering NE870 3BSE080239R1, mount the unit securely onto DIN‑rail. Wire up two independent redundant DC power feeds within 16‑60 V DC range. Separate control‑network Ethernet cables from high‑power cables and apply proper shielding. Complete RNRP, firewall policy and routing configuration via CLI console; save configuration to USB storage before putting online. Verify port assignment matches 800xA network design documentation.

maintenance recommendations: Check LED status and cabinet ventilation during routine inspections. Keep USB‑saved configuration backup file for fast spare‑unit replacement. Monitor alarm‑output signals connected to plant alarm‑system. Do not open the aluminium housing on‑site. If persistent routing or firewall anomalies occur, cross‑check network topology and configuration before replacing hardware. NE870 3BSE080239R1 contains no field‑serviceable internal assemblies; return defective units to ABB‑authorised service centres.

Product Warranty & Support

Each NE870 3BSE080239R1 passes factory port testing, RNRP redundancy verification and firewall function validation before shipment. Standard equivalent warranty covers manufacturing defects for 12 months from delivery date. Spare‑part sourcing, remote technical guidance and SAT‑support services are available for network‑design review, commissioning and fault‑shooting. Application engineers provide support for RNRP setup, firewall‑policy configuration and DCS network‑segmentation implementation. Long‑term spare‑parts inventory mitigates obsolescence risk for installed System 800xA automation assets.
