ABB RTU560 Advanced Remote Terminal Unit

Description

RTU560

The ABB RTU560 is an advanced remote terminal unit designed to serve as the critical interface between field devices and SCADA systems in distributed automation architectures. As a core component of modern remote monitoring solutions, it combines high-speed data acquisition, powerful control logic execution, and multi-protocol communication capabilities in a single, ruggedized platform. This RTU acts as the “eyes and hands” of the SCADA system, collecting data from sensors, meters, and protection devices while executing control commands from central operators.

RTU560

The ABB RTU560 integrates seamlessly with ABB’s Relion® protection relays—including models like the ABB RET650 and ABB REU615 HBUAEAADANB6ANN1XG—as well as third-party field equipment, creating a unified monitoring ecosystem. Its modular design supports both small-scale installations with basic I/O requirements and large-scale systems requiring hundreds of data points. What makes the ABB RTU560 particularly valuable is its ability to operate autonomously during communication outages, executing pre-programmed control sequences to maintain system stability until connectivity is restored.

Main features and advantages:

The ABB RTU560 delivers exceptional performance through a powerful processing platform that handles up to 2048 I/O points with scan rates as fast as 100ms, ensuring timely data collection and control execution. It features advanced communication capabilities including redundant Ethernet ports, cellular modem support, and satellite communication interfaces, enabling reliable data transmission even in remote locations with limited infrastructure. The RTU’s built-in programmable logic controller (PLC) functionality allows engineers to implement custom control strategies, alarm conditions, and data processing rules without requiring external programming tools.

Hardware design highlights include a rugged aluminum enclosure that withstands extreme temperatures from -40°C to +70°C, vibration, and electromagnetic interference—making it suitable for installation in unconditioned outdoor cabinets and harsh industrial environments. The RTU supports hot-swappable I/O modules, allowing for field upgrades and maintenance without system downtime. Its low-power consumption design enables operation from solar power systems in off-grid locations, while redundant power supplies ensure continuous operation during utility power interruptions.

Application areas:

In distributed power networks, renewable energy installations, and remote substation operations, maintaining visibility and control over geographically dispersed assets is critical for ensuring reliable power delivery and rapid response to system events. These environments present unique challenges, including limited on-site personnel, harsh environmental conditions, and the need to integrate diverse equipment into a cohesive monitoring system. Whether managing rural distribution networks, monitoring wind farm assets, or controlling pipeline pumping stations, operators require robust remote terminal units (RTUs) that can collect critical data, execute control commands, and communicate reliably over long distances.

This is where the ABB RTU560 excels, serving as a high-performance remote terminal unit for supervisory control and data acquisition (SCADA) applications across power and industrial sectors. In utility distribution networks, it connects to protection relays and field devices, providing real-time data on feeder status and enabling remote switching operations. In renewable energy plants, it monitors inverter performance, weather conditions, and energy production, ensuring optimal operation of dispersed assets. Used in remote monitoring for decades, the ABB RTU560 has proven its reliability in applications requiring secure communication, rugged construction, and flexible integration—making it a trusted choice for utilities, renewable energy developers, and industrial operators worldwide.

Installation and maintenance:

Before installing the ABB RTU560, conduct a site survey to determine optimal mounting location, ensuring protection from direct sunlight, excessive moisture, and physical damage. Verify that the power supply can accommodate the RTU’s requirements, including any additional I/O modules, and ensure proper grounding according to IEC 61010 standards using a dedicated 6mm² grounding conductor. Plan cable routing to minimize electromagnetic interference, separating power and communication cables by at least 300mm where possible.

For installation, ensure the mounting surface can support the unit’s weight and provide adequate ventilation—maintaining at least 100mm clearance around the RTU for airflow. After physical installation, verify all wiring connections against the schematic diagrams, paying special attention to signal polarity for analog inputs. Configure communication parameters to match the SCADA system requirements, and perform initial functional tests to confirm data acquisition and control command execution.
