ABB 3BHL000986P7001
Product Introduction
The ABB 3BHL000986P7001 is a mission-critical fiber optic communication module engineered for ABB’s S800 I/O High Integrity system. Designed for safety-critical applications, this redundant interface enables ultra-reliable PROFIBUS DP connectivity between distributed I/O islands and AC 800M High Integrity Controllers in ABB’s 800xA Safety Systems. The 3BHL000986P7001 converts electrical signals to optical transmission, providing complete galvanic isolation while eliminating electromagnetic interference (EMI) risks in hazardous environments.
As part of ABB’s fault-tolerant architecture, this module implements dual independent optical channels with automatic switchover during fiber breaks or transmitter failures. Its SIL 3 certification ensures compliance with stringent functional safety requirements for emergency shutdown (ESD) systems and fire & gas detection. The 3BHL000986P7001 integrates seamlessly with Control Builder Safe software, enabling certified safety logic deployment across extended distances.
Core Advantages and Technical Highlights
Zero-Failure Redundancy:
Dual optical transceivers operate in parallel with <1μs switchover latency, maintaining PROFIBUS DP-V1 communication during single-point failures. Automatic signal compensation adjusts for fiber degradation.
EMI Immunity & Safety:
Optical isolation eliminates ground loops and withstands 4 kV surge/8 kV ESD. SIL 3 hardware diagnostics include transmitter/receiver watchdog, bit error rate monitoring, and end-to-end heartbeat verification.
Deterministic Performance:
Hardware-based time-stamping synchronizes safety events with 1 ms resolution. Supports PROFIsafe protocol for safety instrumented functions (SIFs).
Extreme Environment Operation:
-40°C cold-start capability with conformal-coated PCBs for humidity/corrosion resistance. Vibration tested per IEC 60068-2-6 (10g @ 150Hz).
Typical Application Scenarios
The ABB 3BHL000986P7001 is indispensable in offshore platforms, where it connects subsea safety valves to central ESD systems across 1.5 km fiber runs, immune to lightning strikes. In chemical plants, it links toxic gas detectors in SIL 3-rated fire & gas loops, withstanding HF acid vapors.
Power generation facilities deploy the module between turbine trip systems and distributed I/O, utilizing fiber immunity to switchyard EMI. Pharmaceutical batch reactors use it for emergency pressure relief control, where copper-free signals prevent ignition in Class I Div 1 zones.
