NMBA-01 3BHL000510P0003: Product OverviewThe ABB NMBA-01 (3BHL000510P0003) is a network communication module within ABB’s Advant OCS (Advanced Open Control System) series, designed to serve as a fault-tolerant gateway for controller-to-I/O and controller-to-field device communication in distributed control architectures. Its primary role is to ensure deterministic, high-availability data exchange between Advant OCS controllers (e.g., AC410) and distributed I/O modules or third-party devices, mitigating single-point communication failures in continuous process industries.Functionally, the module implements a dual-redundant active/standby architecture with automatic failover (≤50ms), processing cyclic data (real-time I/O updates) and acyclic messages (diagnostic/config commands). It supports Ethernet/IP and Profibus DP protocols, enabling integration with ABB S800 I/O and legacy field devices. As part of the Advant OCS family, the NMBA-01 leverages the platform’s modular scalability, compatibility with ABB’s legacy engineering tools, and seamless integration with asset management systems. Benefits include simplified network expansion, reduced validation effort, and minimized risk of unplanned downtime due to communication faults.
Communication Protocols: Ethernet/IP, Profibus DP (up to 12 Mbps), Modbus TCP (optional)
I/O Device Capacity: Up to 64 devices per segment (Ethernet/IP/Profibus DP)
Data Throughput: Up to 12,000 I/O points per second (cyclic exchange)
Operating Temperature: -40°C to +70°C
Humidity Range: 5% to 95% non-condensing
Power Supply: 24V DC (nominal, 18-32V DC range), redundant inputs supported
Power Consumption: 10W (typical, dual ports active)
Dimensions: 245mm x 135mm x 115mm (width x height x depth, fits Advant OCS rack)
Weight: 1.0kg
Certifications: CE, UL, cULus, SIL 2 (IEC 61508, when integrated with safety logic)
Core Features & Customer ValueThe NMBA-01 3BHL000510P0003 addresses critical communication reliability challenges in industrial automation. Its dual-redundant architecture ensures uninterrupted data flow, with failover times (≤50ms) compliant with SIL 2 requirements for safety-related systems. In a refinery’s catalytic cracker control system, this prevents loss of I/O updates during a module fault, avoiding unplanned shutdowns.Support for Ethernet/IP and Profibus DP enables integration with ABB S800 I/O and legacy devices (e.g., Siemens S7-300 PLCs), eliminating protocol converters. For engineers, this simplifies system expansion—e.g., adding a new I/O rack to an existing Advant OCS network—while preserving prior investments in field wiring.High data throughput (12,000 I/O points/second) efficiently handles dense networks, such as power plant boiler control systems with 5,000+ temperature/pressure signals. Built-in diagnostics (LED indicators, error logs) monitor link status, signal integrity, and redundant path synchronization, reducing troubleshooting time for communication faults from hours to minutes.Hot-swap capability allows replacement without de-energizing the rack, critical for continuous processes like chemical manufacturing. Integration with ABB’s legacy engineering tools streamlines configuration, enabling engineers to reuse communication profiles across projects and cut commissioning time by 15-20%.

Typical ApplicationsThe ABB NMBA-01 3BHL000510P0003 is deployed in Advant OCS environments requiring redundant communication. In a petroleum refinery’s crude distillation unit, it links an AC410 controller to 40 S800 I/O stations (monitoring 8,000+ signals) via Ethernet/IP. Dual-port redundancy ensures continuity if a cable is damaged during maintenance.At a chemical plant’s ethylene cracker, the module connects the safety controller to Profibus DP-linked emergency shutdown (ESD) inputs (flame detectors, pressure switches). Its ≤50ms failover time meets SIL 2 requirements, while Modbus TCP transmits ESD status to the historian.In a municipal water treatment plant, the NMBA-01 interfaces the controller with remote pump stations (via Modbus TCP). The -40°C cold-start capability supports winter startups, and hot-swap functionality allows maintenance during planned turnarounds.
