ABB RTU560 – Modular Grid Automation Remote Terminal Unit
Product Overview
The RTU560 is a high-performance modular remote terminal unit developed by ABB for substation automation, oil & gas pipeline control and distributed utility monitoring. It acts as an on-site data acquisition and logic execution hub, collecting real-time signals from IEDs, sensors and switchgear while transmitting processed data to central SCADA control systems. This unit resolves multi-protocol compatibility and remote site unmanned operation challenges, supporting flexible system expansion and redundant communication architecture for power grids, water plants and railway traction power systems. Its industrial-hardened hardware maintains stable operation in outdoor and high-electromagnetic-interference environments.

ABB RTU560
Key Features and Benefits
- Full Modular Expandability: Supports hot-swappable communication, I/O and power modules, scalable from small pump stations to large primary substations with up to 16 CMU boards for mass data processing.
- Multi-Level Redundancy Options: Configurable redundant power supply, Ethernet links and main control modules to eliminate single-point failure for critical grid infrastructure.
- Wide Protocol Compatibility: Natively connects legacy field devices and modern digital relays, enabling seamless system retrofitting without full infrastructure replacement.
- Local Logic & Data Storage: Embedded real-time operating system executes site control logic; onboard SD card archives time-stamped fault records and load profile data for post-event analysis.
- Industrial Environmental Resilience: Galvanically isolated signal circuits and anti-vibration rack design fit unmanned remote sites, pipelines and outdoor distribution substations.

Installation and Maintenance
The RTU560 uses standard subrack rack installation, requiring certified automation technicians to complete backplane wiring and protocol configuration per ABB official engineering guidelines. Before deployment, inspect module terminals and Ethernet ports for dust or corrosion to avoid signal loss. Routine maintenance includes quarterly dust removal from ventilation slots and backup configuration export to external storage.
All replacement operations require power isolation of the target subrack to prevent bus communication interruption. The hot-swap module design shortens system downtime during component replacement, while built-in self-diagnostic tools speed up fault localization for long-term remote site operation.
