The ABB AI810 (3BSE008516R1) is an 8-channel analog input module designed for the ABB S800 I/O platform. It provides high-precision signal acquisition for industrial control systems, supporting both current and voltage inputs with independent configuration per channel.

Features

• 8 single-ended unipolar input channels.
• Configurable for 0–20 mA, 4–20 mA, 0–10 V, or 2–10 V DC signals.
• 12-bit resolution for accurate process measurement.
• Integrated HART communication support for transparent digital data transmission.
• Robust protection with PTC current-limiting resistors, capable of withstanding 30 V DC overvoltage.
• Galvanic isolation of the channel group from ground.

Applications

• Refinery process control (pressure, level, and flow monitoring).
• Turbine auxiliary systems (lube oil, cooling, and steam flow).
• Boiler control and combustion management.
• Renewable energy infrastructure (pitch control and hydraulic pressure monitoring).

Technical Specifications

Installation Guidelines

• Ensure the system is powered down before installing or removing the module from the Module Termination Unit (MTU).
• The AI810 is compatible with various MTUs including TU810, TU812, TU814, TU818, TU830, TU833, TU835, TU838, and TU850.
• Use shielded cabling for field inputs to minimize EMI interference, especially in high-noise industrial environments.
• Maintain proper grounding practices for the S800 I/O rack to ensure signal integrity.
• Handle with care to prevent electrostatic discharge (ESD) damage to the module components.
