Core Specifications
1.Network & Communication Parameters
Protocol Support: Exclusive to PROFIBUS-DP (compliant with EN 50170 standard for industrial fieldbus communication)
Channel Configuration: 1 primary channel (for connecting to the non-redundant PROFIBUS master) with 2 redundant output channels (for the parallel redundant PROFIBUS lines)
Communication Speed: Auto-adaptive to the PROFIBUS-DP network speed (no manual configuration required; synchronizes with the master’s baud rate, supporting common industrial rates from 9.6 kbit/s to 12 Mbit/s)
Redundancy Logic: Automatically manages traffic between the two redundant lines—if one line fails (e.g., cable break, short circuit), communication seamlessly switches to the alternate line without data loss or network interruption
2.Physical & Mechanical Specifications
Product Net Weight: 0.46 kg (lightweight design for easy mounting and integration into control cabinets)
Gross Volume: 0 m³ (dimension data not explicitly provided; form factor optimized for compatibility with standard 19-inch industrial racks and ABB S900 I/O enclosures)
Mounting: DIN rail mounting (compliant with EN 50022 standards) for straightforward installation alongside other PROFIBUS components (e.g., masters, slaves, couplers)
3.Origin & Regulatory Compliance
Country of Origin: Malta (MT)
Customs Tariff Number: 85389091 (classified as "Parts suitable for use solely or principally with the apparatus of heading 85.35, 85.36 or 85.37 - Other" under global customs standards)
System Compatibility: Fully integrated with ABB 800xA (versions 4.1, 5.0, 5.1) and S900 I/O systems; compatible with PROFIBUS-DP masters (e.g., ABB AC 800F controllers) and slaves (e.g., S800/S900 I/O modules, field transmitters)
Key Functional Features
Line Redundancy Conversion: Transforms a single PROFIBUS-DP line into two redundant lines, eliminating single points of failure in the communication network. This is critical for safety-instrumented systems (SIS) and mission-critical processes where network downtime could cause production losses or safety hazards.
Seamless Failover: Detects line faults (e.g., open circuits, short circuits) in real time and switches communication to the healthy line within milliseconds—no manual intervention required, ensuring uninterrupted data transmission between the PROFIBUS master and field devices.
Flexible Deployment: Can be installed at three key points in the network:
Directly after a PROFIBUS master (to redundant-enable the master’s output).
Before a segment of multiple PROFIBUS slaves (to protect a group of devices).
Before an individual slave (for targeted redundancy of critical field devices).
Backward Compatibility: Works with both redundant and non-redundant PROFIBUS slaves—non-redundant slaves can be assigned to either of the two redundant lines, while slaves with redundant interfaces can connect directly to both lines for maximum reliability.
