3BHE017628R0002 PPD115A02 SG579989013
- 3BHE017628R0002: ABB’s global primary part number for traceability, denoting compatibility with Symphony Plus DCS (used in power plants and heavy industry) and compliance with IEC 61508 SIL 2 safety standards.
- PPD115A02: Functional model code; “PPD” stands for “Power & Peripheral Driver,” specifying dual roles: 1) redundant 24 V DC power supply for DCS I/O modules, and 2) interface for peripheral signal transfer (e.g., status monitoring, fault alarming); “115” indicates 15 A total output current, “A02” denotes hardware revision optimized for extended temperature operation.
- SG579989013: ABB’s secondary part number for regional inventory management, confirming identical functionality to 3BHE017628R0002.
- Core Positioning: The “redundant power and signal hub for Symphony Plus DCS,” ensuring continuous power to I/O modules and reliable peripheral communication—critical for safety-critical processes like turbine control and boiler monitoring.)
2. Product Description
- Power Redundancy: Features dual hot-swappable power supply channels (1+1 redundancy) with automatic failover. If one channel fails, the other immediately takes over (≤10 ms switchover time), ensuring no power interruption to I/O modules (e.g., analog input modules, safety I/O) that control critical processes.
- Signal Integrity: Acts as a dedicated interface for peripheral signals (e.g., module status, fault alarms, configuration data) between Symphony Plus controllers (e.g., AC 800PEC) and I/O racks. Integrates EMC filters (compliant with EN 61000-6-2) to suppress noise from nearby high-voltage equipment (e.g., generators, transformers), preventing signal distortion.
- Safety Compliance: Meets IEC 61508 SIL 2 for power supply and signal path components, making it suitable for safety-related loops (e.g., boiler water level control, turbine overspeed protection) in power plants and refineries.
