Functions & Features
Flexible Bus Extension & Seamless Integration
Designed specifically for the ABB Symphony Plus control system, it can transparently extend the HN800 IO bus and also expand to the CW800 bus to achieve point-to-point communication between SD series and HPC800 series controllers. It integrates quickly into the system without complex protocol conversion.
Supporting multiple mainstream industrial bus protocols, it remotely extends the bus interface of the control master, breaking the physical distance limit of traditional bus transmission. It also expands multiple bus nodes to connect a large number of I/O modules, sensors, actuators, and other intelligent devices, effectively solving the problem of insufficient nodes on a single bus and improving system scalability and deployment flexibility[2].
High-Speed Stable Transmission & Strong Anti-Interference
Equipped with a high-speed data processing chip, it supports stable 4 Mbps transmission and Ethernet 10/100 Mbps auto-negotiation, with data rate consistent with the master bus to ensure delay-free interaction between control commands and field feedback signals, meeting the strict real-time requirements of industrial automation systems.
It features excellent anti-electromagnetic interference performance compliant with IEC 61000 series EMC standards, effectively suppressing interference from inverters, motors, and other equipment. Combined with the anti-interference advantage of optical fiber transmission, it avoids data congestion and packet loss, ensuring the integrity and stability of signal transmission.
Redundancy & Fault Tolerance & Convenient O&M
The module provides complete redundant configuration for bus redundancy extension, ensuring high availability and reliability. Data transmission remains uninterrupted even in extreme fault scenarios, reducing downtime losses.
Modular design enables easy installation and removal; faulty parts can be replaced individually without full disassembly, greatly improving maintenance efficiency. It supports plug-and-play with no complex configuration and features intuitive fault diagnosis to monitor bus communication and device status in real time, issuing alarms for abnormalities to help O&M personnel quickly locate and resolve issues[2].
Industrial-Grade Reliability & Wide Compatibility
Constructed with high-quality industrial-grade components and a metal casing, it has passed rigorous high/low-temperature, EMC, and vibration tests. It offers excellent dust and moisture protection with an IP65 rating, suitable for harsh industrial environments.
Its wide operating temperature range (-20 °C ~ +60 °C) requires no additional temperature control equipment and adapts to extreme conditions. As part of the ABB automation ecosystem, it connects seamlessly with mainstream control equipment such as ABB AC500 series PLC and 800xA DCS systems. Its open interface design also ensures compatibility with other brands of industrial control equipment, providing broad applicability.

FAQs & Solutions
How to achieve seamless integration with the Symphony Plus control system?
The extender is specially designed for the Symphony Plus control system and supports transparent extension of the HN800 IO bus. It is plug-and-play with no complex protocol debugging or parameter configuration. Simply connect the extender to the control master and remote devices via optical fiber or shielded twisted pair without modifying the existing system architecture to achieve seamless integration. It is compatible with the current bus protocol to ensure high-speed and stable data transmission.
How to troubleshoot communication interruptions during operation?
First, verify that the power supply to the extender is normal (stable 24 VDC, no fluctuation or reverse polarity). Next, check that the transmission medium (optical fiber or twisted pair) is correctly and securely connected, and inspect for damage or breaks. Then, confirm that the number of bus nodes does not exceed the maximum supported limit and that redundant configurations are functioning properly. Finally, check the device fault alarm signals to identify the cause. If the extender itself is faulty, use the modular design for quick replacement to restore system operation, and contact ABB after-sales service for repair.
How to select the appropriate transmission medium and ensure stable long-distance transmission?
For long-distance industrial scenarios, 62.5/125 μm multi-mode optical fiber cable is preferred, enabling stable transmission up to 3 km. For short distances, shielded twisted pair can be used to reduce electromagnetic interference.
During use, ensure the transmission medium meets industrial standards and avoid close proximity to strong electromagnetic interference sources. Regularly inspect the connectors, clean dust and oxidation, and ensure secure connections. Enable redundant configuration to further improve the stability and reliability of long-distance transmission.
