ABB DSRB310 Filling Module 

1. Key Parameters

• Product Model: DSRB310
• Product Series: ABB AC500 Premium Series Industrial Filling Modules (Multi-Slot Backplane Protection)
• Core Function: Seals 3 consecutive unused slots in AC500 Premium backplanes to prevent dust/moisture ingress; enhances EMI shielding for large open backplane areas; reinforces backplane structural stability (prevents warping from uneven pressure); blocks accidental contact with live backplane connectors; preserves cabinet airflow for thermal management of adjacent modules
• Mechanical & Dimensional Specifications:

  Parameter	Details	Performance Metrics
  Mechanical Design	- Dimensions: 300mm (W) × 180mm (H) × 35mm (D) (occupies 3 consecutive AC500 Premium slots) - Mounting Type: Tool-less snap-on installation (integrated plastic clips for each slot; no screws required) - Housing Material: Flame-retardant thermoplastic (UL 94 V0) with nickel-plated EMI shielding layer (10μm thickness) - Weight: Approximately 220g - Reinforcement Structure: Internal ribbed thermoplastic frame (enhances rigidity for multi-slot coverage)	3-slot design covers large unused backplane areas (reducing the need for multiple single-slot blanks); internal ribs prevent bending under cabinet pressure; tool-less installation cuts setup time by 60% vs. screw-mounted alternatives

• Environmental & Protective Specifications:

  Parameter	Details	Performance Metrics
  Environmental Sealing	- Ingress Protection (IP): IP54 (when installed; dust-tight, water spray-resistant) - Sealing Mechanism: Dual-layer foam gasket (urethane, 3mm thickness) along all edges + perimeter lip (forms a tight seal with backplane and cabinet) - EMI Shielding: Nickel-plated layer (provides 25dB attenuation at 100MHz~1GHz, supplementing cabinet EMI protection)	IP54 rating blocks fine industrial dust (e.g., metal shavings, flour) and occasional water spray (e.g., cabinet cleaning); 25dB EMI attenuation reduces interference from high-power equipment (e.g., VFDs, welding machines)
  Environmental Ratings	- Operating Temperature Range: -30℃~+85℃ (-22℉~185℉) - Storage Temperature Range: -40℃~+90℃ (-40℉~194℉) - Humidity Tolerance: 5%~95% RH (non-condensing, 40℃) - Vibration Resistance: 10~500Hz, 1.2g acceleration (IEC 60068-2-6) - Shock Resistance: 20g (11ms half-sine, IEC 60068-2-27) - EMC Compliance: EN 61000-6-2 (immunity: Level 3); EN 61000-6-3 (emission: Class B)	Wide temperature range suits extreme environments (e.g., arctic oil fields, desert solar plants); 1.2g vibration resistance prevents dislodgment during cabinet transportation or equipment operation

• Compliance Specifications:

  Parameter	Details	Performance Metrics
  Safety & Compliance	- Flame Retardancy: UL 94 V0 (self-extinguishes within 10 seconds of flame removal) - Electrical Insulation: 1.5kV AC (between housing and backplane pins, 1 minute) - RoHS Compliance: EU RoHS 2.0 (Restriction of Hazardous Substances) - Industry Standards: CE, UL 508 (industrial control), IEC 60529 (IP rating), IEC 61000-6-2 (EMC)	1.5kV insulation provides enhanced protection against accidental short circuits; UL 94 V0 rating reduces fire risk in cabinets with high-voltage components

2. Core Features

• 3-Slot Comprehensive Coverage: Occupies 3 consecutive slots in AC500 Premium backplanes—eliminates gaps between multiple single-slot blanks, providing uniform sealing and EMI shielding for large unused areas; reduces inventory complexity by replacing 3 single-slot blanks with one module.
• Enhanced Environmental Protection: Dual-layer foam gasket + IP54 rating—blocks dust accumulation (a leading cause of backplane connector corrosion) and resists water spray, extending backplane lifespan by 4~6 years in harsh industrial environments (e.g., chemical plants, mining facilities).
• Superior EMI Shielding: Nickel-plated layer with 25dB attenuation—supplements the control cabinet’s electromagnetic shielding, reducing interference from external equipment (e.g., high-power motors, inverters) and ensuring stable operation of adjacent AC500 Premium modules (e.g., DSPC155 processor, DSPB112 signal boards).
• Rigid Structural Reinforcement: Internal ribbed frame—prevents large multi-slot backplane sections from warping due to uneven pressure (e.g., cabinet door closure, module insertion/removal); maintains alignment of backplane pins, ensuring reliable connections for future module additions.
• Tool-Less Quick Installation: Snap-on clips for each slot—enables fast, tool-free mounting (installation time <1 minute) and removal; no screws or specialized tools needed, simplifying PLC system reconfiguration (e.g., adding DSMB series I/O modules later).
• High Safety Insulation: 1.5kV AC electrical insulation—provides enhanced protection against accidental contact with live backplane pins during maintenance, reducing electric shock risk for technicians; non-conductive thermoplastic housing eliminates short-circuit hazards.
• Seamless AC500 Premium Integration: Matches the mechanical profile (height, depth, mounting) of AC500 Premium multi-slot modules—blends with existing system aesthetics; compatible with all AC500 Premium backplane versions (v3.0+), ensuring plug-and-play functionality.

3. Application Fields

• Large-Scale Manufacturing: Multi-Slot Protection:
  • Automotive Mega-Plants: Fills unused 3-slot sections in AC500 Premium backplanes for robotic cell controllers—blocks metal dust from welding operations and prevents backplane pin corrosion; EMI shielding reduces interference from robot drives, ensuring stable communication with DSPC155 processors.
  • Electronics Semiconductor Fabs: Seals 3-slot areas in cleanroom PLC cabinets—IP54 rating resists cleanroom chemicals (e.g., isopropyl alcohol) and prevents particulate ingress; rigid frame maintains backplane alignment for future additions of DSPB signal processing modules.
• Process Plants: Harsh Environment Sealing:
  • Chemical Complexes: Protects AC500 Premium backplanes in corrosive environments—dual-layer gasket blocks corrosive gas ingress (e.g., chlorine, sulfur dioxide); 1.5kV insulation withstands electrical noise from chemical pumps, ensuring reliable backplane performance.
  • Oil Refineries: Fills 3-slot spaces in outdoor substation PLC cabinets—-30℃~+85℃ temperature tolerance withstands extreme weather; vibration resistance prevents dislodgment during storm-induced cabinet movement, maintaining sealing integrity.
• Energy & Utilities: Structural Stability:
  • Wind Farms (500MW+): Seals unused 3-slot areas in turbine controller cabinets—EMI shielding reduces interference from wind turbine inverters; rigid frame prevents backplane warping in high-vibration turbine nacelles, ensuring reliable connections for future monitoring modules.
  • Water Treatment Plants: Protects AC500 Premium backplanes in damp pump station cabinets—IP54 rating blocks moisture ingress (prevents backplane pin rust); dual-layer gasket maintains sealing even in high-humidity environments.
• PLC System Expansion: Future-Proofing:
  • Reserved Expansion Slots: Fills 3-slot sections reserved for future module additions (e.g., planning to add 3 DSMB178 digital I/O modules later)—keeps backplane clean and aligned, ensuring plug-and-play compatibility when expanding the system; eliminates the need to clean or repair backplanes before adding new modules.
  • Temporary Module Removal: Protects slots when large modules (e.g., DSPC171 premium processor) are temporarily removed for repair—maintains environmental sealing and EMI shielding during downtime, avoiding backplane damage that would cause extended system outages.
