ABB AI895 3BSC690086R1 8ch 4-20 MA HART Analog Input S800 I/O Module

ABB AI895 3BSC690086R1 8ch 4...20mA HART Analog Input S800 I/O Module

Overview
The AI895 3BSC690086R1 is an ABB S800 I/O module engineered for high-integrity analog input in hazardous-area applications. With eight galvanically-isolated, intrinsically-safe 4-20 mA channels and full HART 7 support, it provides real-time process data and device diagnostics for separators, reactors, oil & gas skids, and chemical plants—all while meeting SIL 2 / SIL 3 safety requirements.

Key Features
• 8 channels, 4-20 mA, 16-bit resolution, ±0.1 % accuracy
• Intrinsically Safe: Ex ia IIC T4 Ga, ATEX & IECEx certified
• HART 7 Pass-Through: online configuration, valve signatures, asset diagnostics
• Hot-swappable on S800L or S800 I/O rack; auto-detect in Studio 5000 or Compact Control Builder
• Redundancy Ready: supports dual CPUs and dual I/O buses for fault-tolerant architectures
• Wide ambient range –25 °C…+70 °C (-13 °F…+158 °F)
• EMC per IEC 61000-6-4 / 61000-6-2; NAMUR NE21 compliance
• MTBF > 200 kh; 10-year warranty with ABB ServiceGuard

Typical Applications
• Temperature, pressure & flow transmitters in Zone 0/1
• Valve positioners with HART partial-stroke testing
• SIL-rated emergency shutdown (ESD) loops
• Retrofit of legacy AI820/AI830 modules without re-wiring
