ABB RER103 Bus Connection Module – Fiber-Optic to RS-485 Communication Converter
The ABB RER103 Bus Connection Module is an advanced communication interface engineered for seamless integration of protection relays into fiber-optic substation automation networks. Designed specifically for ABB RE500 series protection devices, this module converts optical signals from fiber-optic communication buses into reliable electrical RS-485 signals, ensuring robust data transmission in mission-critical power distribution environments.
Key Technical Specifications
- Model Number: RER103
- Manufacturer: ABB
- Interface Type: Fiber-optic input to RS-485 electrical output
- Protocol Support: SPA (Station Protection Automation), LON®, IEC 60870-5-103
- Power Supply: 24 V DC nominal (system-powered)
- Operating Temperature: -25°C to +55°C
- Dimensions: 35 mm × 73 mm × 20 mm (compact DIN-rail mountable)
- Weight: 0.7 kg
- Mounting Options: DIN rail or panel mount in control cabinets
- Protection Features: Galvanic isolation, high EMI/RFI resistance
- Compliance: IEC 60870-5-103, CE marked, UL listed
Application Scenarios & Solutions
Substation Automation Integration: The RER103 serves as a critical bridge in modern digital substations, enabling legacy RS-485-based protection relays to communicate over high-speed fiber-optic networks. This allows utilities to modernize communication infrastructure without replacing existing protection equipment, significantly reducing capital expenditure.
Multi-Protocol Environments: In substations where multiple communication protocols coexist—such as SPA for ABB devices, LON for building automation integration, and IEC 60870-5-103 for SCADA connectivity—the RER103 provides flexible protocol conversion, ensuring interoperability across diverse automation platforms.
Harsh Industrial Conditions: With an extended operating temperature range and robust galvanic isolation, the module excels in outdoor switchyards, underground vaults, and high-EMI environments where signal integrity is paramount. Its compact form factor allows installation in space-constrained control panels.
Innovative Features & Benefits
Optical-to-Electrical Signal Conversion: Unlike standard communication modules, the RER103 employs advanced optical transceivers that maintain signal fidelity over long fiber runs (up to several kilometers), eliminating ground loop issues and electromagnetic interference common in copper-based systems.
Hot-Swappable Design: The module supports field replacement without system shutdown, minimizing downtime during maintenance operations—a critical advantage in 24/7 power distribution networks.
Diagnostic LED Indicators: Real-time status LEDs provide instant visual feedback on power, communication activity, and fault conditions, accelerating troubleshooting and reducing mean time to repair (MTTR).
