ABB 3BUS208796-001 Power Signal Conditioning Board
Product Description
A dedicated power signal conditioning board for ABB industrial automation systems (e.g., AC 800M, Symphony Plus). It specializes in stabilizing and conditioning power signals (e.g., voltage regulation, noise filtering) for downstream I/O modules or controllers, ensuring reliable power supply and reducing signal interference—critical for stable operation of industrial control components in harsh power environments.
Key Specifications
- Input Power: 24V DC (18-30V DC) wide-range input; supports 110/220V AC (via external rectifier module).
- Output Power: 24V DC stabilized output; max current 5A; voltage ripple ≤50mV.
- Signal Conditioning: Built-in low-pass filter (100Hz cutoff) for power noise suppression; surge protection (IEC 61000-4-5, ±2kV).
- Monitoring Function: Real-time output voltage/current monitoring; overvoltage (30V DC) and overcurrent (6A) protection.
- Environment: Operating temp -40°C to +70°C; humidity 5%-95% (non-condensing); IP20.
- Mechanical: 35mm DIN rail-mounted; dimensions 120×85×25mm; compatible with ABB standard I/O racks.
- Isolation: 2.5kV AC isolation between input and output; 5kV AC isolation from system ground.
- Catalog No.: 3BUS208796-001 (primary model; no regional variations for core specs).
Advantages & Features
- Wide Input Adaptability: 18-30V DC wide-range input fits unstable industrial power grids; AC input support via rectifier expands application scenarios.
- High-Stability Output: Voltage ripple ≤50mV ensures stable power for precision I/O modules (e.g., analog input modules), avoiding signal distortion.
- Dual Protection Mechanisms: Surge protection resists power spikes; overvoltage/overcurrent protection prevents damage to downstream components.
- Real-Time Monitoring: Output voltage/current feedback enables timely detection of power anomalies (e.g., overload), reducing system downtime.
- Easy Integration: DIN rail design matches ABB I/O modules; plug-and-play with ABB control racks, no extra adapters needed.
Application Fields
- Industrial Control Cabinets: Powers ABB digital/analog I/O modules (e.g., DO820, IMDSM-04) in control cabinets, stabilizing power for signal acquisition/transmission.
- Power Plant Auxiliaries: Conditions power for boiler auxiliary system controllers, resisting voltage fluctuations from high-voltage equipment.
- Chemical Plants: Supplies filtered power to reactor temperature control modules, avoiding power noise affecting precision temperature monitoring.
- Manufacturing Lines: Powers robotic control components in automotive assembly lines, ensuring stable operation of motion control modules.
Precautions
- Input Matching: Confirm input power type (DC/AC) before wiring; use 110/220V AC only with compatible ABB rectifier modules.
- Wiring Safety: Use 1.5-4mm² copper wires for input/output; tighten terminals to 1.2-1.5N·m torque to prevent loose connections and overheating.
- Load Management: Do not exceed 5A max output current; distribute load evenly if powering multiple modules (e.g., ≤3 I/O modules per board).
- Environmental Installation: Avoid direct sunlight, corrosive gas, or water splashes; keep 10cm clearance around the board for heat dissipation.
- Maintenance: Check output voltage monthly with a multimeter; clean dust from vents every 3 months. Replace if overvoltage/overcurrent protection triggers repeatedly (indicates internal fault).
