ABB RMU610 2VAA008425R1 Rack Mounting Unit
Modular Mounting Frame for Symphony Plus HN800 I/O System Modules
1. Core Product Overview
The ABB RMU610 (2VAA008425R1) is a dedicated rack mounting unit engineered for the Symphony Plus HN800 I/O system, serving as the structural foundation for mounting, securing and powering HN800 series I/O modules, bus extenders and auxiliary components in industrial control cabinets. It features a modular, compact mechanical design optimized for standard industrial rack enclosures, providing precise mounting positions and robust mechanical fixation for HN800 modules to prevent displacement caused by industrial vibration and shock. The unit integrates a centralized 24VDC power distribution system with overvoltage and overcurrent protection, delivering stable power to all mounted HN800 components while simplifying cabinet wiring and power management. Built with industrial-grade rugged materials and anti-corrosion coating, it operates stably in harsh industrial environments (-25°C~+70°C) with strong electromagnetic interference, and is fully compatible with all HN800 series peripherals (e.g., CHBX01L bus extender), forming a complete, scalable mounting and power solution for HN800 I/O systems in process control and industrial automation applications.

2. Mechanical Design & Mounting Performance
The RMU610 2VAA008425R1 features a high-strength steel alloy frame with precision-machined mounting slots, designed to perfectly match the mechanical dimensions of HN800 I/O modules and bus extenders, ensuring a tight, vibration-resistant fit with no loose connections during long-term operation. It supports standard 19-inch industrial rack mounting and DIN rail fixation, with adjustable mounting brackets for flexible cabinet layout and easy integration into existing control system enclosures. The unit incorporates a snap-in locking mechanism for each mounting slot, enabling tool-free installation and replacement of HN800 modules, greatly reducing on-site commissioning and maintenance time. Its rigid structural design withstands industrial vibration (5-50Hz, IEC 60068-2-6) and shock impact (15g, IEC 60068-2-27), preventing module damage and signal interruption caused by mechanical stress. The frame is coated with anti-corrosion and anti-static paint, protecting against rust and electrostatic discharge (ESD) in humid or dusty industrial environments, and the compact form factor maximizes the use of cabinet space for high-density HN800 I/O system configuration.

• Space Optimization: Compact form factor; high-density mounting slots; integrated wiring channels; minimal cabinet footprint; scalable module expansion
3. Power Distribution & Electrical Protection
The RMU610 2VAA008425R1 integrates a centralized 24VDC power distribution system, with a single power input port and multiple isolated power output terminals for each mounted HN800 module, simplifying cabinet power wiring and eliminating the need for separate power supplies for individual components. It supports a wide voltage input range of 24VDC ±15%, adapting to unstable power grid conditions in industrial sites, and the built-in power regulation circuit ensures a stable 24VDC output for HN800 modules with low voltage ripple (<50mV). The unit is equipped with comprehensive electrical protection functions, including overvoltage protection (30VDC cutoff), overcurrent protection (per-channel current limiting) and short-circuit protection, which automatically cut off power to faulty channels to prevent damage to the entire HN800 system and power supply equipment. It also features electrical isolation between the power input and output circuits (2.5kV galvanic isolation), reducing electromagnetic interference between the power supply and signal circuits, and LED power status indicators for each output channel, enabling quick identification of power supply faults for on-site troubleshooting.
