2. Core Features

• Scalable 10-Slot Configuration: Offers 10 standard AC500 slots—supports full system configurations (e.g., 1× DSPC155 processor + 6× DSMB I/O modules + 2× DSPB signal boards + 1× DSRB110 slot filler), eliminating the need for multiple small mainframes and reducing rack space usage by 40% vs. 2U 5-slot alternatives.
• Redundant Power Support: 2 independent power input terminals—enables 1+1 power redundancy (e.g., connecting two 24V DC power supplies); automatically switches to the backup supply if the primary fails, ensuring zero power interruption for critical processes (e.g., chemical batch production).
• High-Speed Stable Data Bus: 100Mbps AC500 Local Bus—ensures low-latency communication (≤100μs) between the processor and I/O modules, critical for time-sensitive applications (e.g., robotic welding, high-speed packaging); bus isolation reduces EMI interference from power circuits, avoiding data corruption.
• Industrial-Grade Structural Rigidity: 1.2mm cold-rolled steel housing with powder coating—provides robust support for fully loaded modules (max 8kg); resists rack vibration and accidental impacts (e.g., during module insertion/removal), preventing module dislodgment and backplane damage.
• Efficient Thermal Management: Optimized internal airflow design (front-to-back ventilation)—works with rack cooling fans to dissipate heat from high-power modules (e.g., DSPC171 processor, 30W); prevents hotspots and ensures all modules operate within -25℃~+70℃, extending component lifespan by 3~5 years.
• Seamless AC500 Integration: Standardized slot design and AC500 Local Bus—auto-detects all compatible modules (no manual configuration required); works with ABB Automation Builder software to monitor mainframe status (power consumption, bus health), reducing system setup time by 50% vs. third-party racks.
• Enhanced Safety & Compliance: UL 508/CSA C22.2 certification + IP20 protection—prevents electric shock (via insulated terminals) and restricts access to live components (via front panel); flame-retardant housing reduces fire risk in racks with other electrical equipment.
