ABB 3BHL000986P0006
Product Introduction
The ABB 3BHL000986P0006 is a fault-tolerant PROFIBUS DP interface module engineered for ABB’s S800 I/O High Integrity safety system. Designed for mission-critical automation, this redundant communication gateway connects AC 800M HI controllers with PROFIBUS DP field devices in safety instrumented systems (SIS) up to SIL 3. The 3BHL000986P0006 features dual independent electrical channels, enabling continuous operation during single-point failures in emergency shutdown (ESD), fire & gas, and turbine protection applications.
Integrated within ABB’s 800xA High Integrity architecture, this module provides galvanic isolation and real-time diagnostics for PROFIBUS DP-V1 networks. Its specialized ASIC processes safety-critical signals with deterministic latency (<1 ms cycle time), synchronizing with Control Builder Safe logic solvers. The 3BHL000986P0006 serves as a robust alternative to fiber optics in environments requiring copper-based connectivity while maintaining EMI resistance through shielded twisted-pair technology.
Core Advantages and Technical Highlights
Dual-Channel Safety:
Parallel A/B buses with <10 μs switchover ensure zero communication interruption during cable breaks or slave failures. Hardware-based PROFIsafe layer meets IEC 61784-3-3 requirements.
Advanced Diagnostics:
Continuous monitoring of signal quality (SNR), slave response time, and cable integrity. Generates detailed fault reports in 800xA Asset Optimization including:
Segment voltage deviation
Bit error rate >10⁻⁷
Slave watchdog timeouts
Extreme Environment Resilience:
-40°C cold-start capability with conformal coating against humidity/chemicals. Withstands 15g vibration (IEC 60068-2-6) and 50g shock. ATEX Cat. 3 certification for Zone 2 hazardous areas.
Engineering Efficiency:
Auto-addressing of safety slaves via Control Builder Safe. Pre-certified function blocks reduce validation time by 60% for SIL 3 applications.
Typical Application Scenarios
The ABB 3BHL000986P0006 secures critical processes in:
Oil & Gas: SIL 3-rated ESD valve control on offshore platforms, with redundancy surviving salt fog corrosion
