Technical Specifications Interface Type: Electrical to optical conversion interface, multi‑mode fiber optic port Communication Rate: 2 Mbps Fiber Transmission Distance: Max 2000 meters for multi‑mode optical fiber Isolation Performance: Complete electrical isolation between local rack and remote communication segment Transient Surge Suppression: 1500 V Operating Power Supply: 24 VDC from system backplane bus Communication Protocol: Proprietary HDLC bus protocol for I/A Series system Operating Temperature: ‑40 ℃ to +70 ℃ Storage Temperature: ‑50 ℃ to +85 ℃ Relative Humidity: 5%‑95%, non‑condensing Mechanical Dimension: Standard single‑slot plug‑in module for Foxboro I/A Series rack Certifications: CE, UL, ATEX, IEC 61508 functional safety compliance
Functional Features Supports electrical‑optical signal conversion for I/A Series control bus. Realizes long‑distance data transmission via multi‑mode optical fiber. Completely eliminates ground loop interference and surge disturbance on copper cable. Built‑in comprehensive self‑diagnosis for optical link loss, optical module failure, power supply and internal circuit faults.
Application Scenarios Process industry distributed control system (DCS). Large petrochemical plant long‑distance control cabinet interconnection. Oil & gas wide‑range production site DCS rack communication. Chemical plant anti‑interference remote bus transmission. 
Structural Characteristics Standard single‑slot plug‑in structure matching Foxboro I/A Series rack. Front panel with status indicator LED lamps for power, optical link status and communication fault. Fiber optic interface connectors located on module front panel.
Working Principle Electrical bus signals from rack backplane enter module internal circuit. Electrical‑optical conversion unit converts electrical signal into optical signal and transmits outward through multi‑mode optical fiber. Received optical signal from remote side is converted back to electrical bus signal and delivered to local rack backplane.
Installation Requirements Install the module into designated slot of Foxboro I/A Series standard rack. Ensure rack ground connection strictly follows system grounding specification. Optical fiber cables shall follow construction specification, avoid sharp bending and extrusion damage.
