Description

The ABB AI835 3BSE008520R1 is an 8-channel analog input module designed specifically for the ABB S800 I/O distributed modular system. It functions as a high-precision interface for acquiring thermocouple and millivolt signals, converting raw analog field measurements into digital values for downstream processing in ABB distributed control systems such as System 800xA.

Mounted on a modular DIN rail base plate, the AI835 integrates directly into S800 I/O stations communicating via ModuleBus. It supports hot-swapping functionality to allow replacement under power without interrupting active process control loops, reducing downtime during maintenance cycles.

Features

  • 8 input channels configured for thermocouple (TC) and millivolt (mV) measurement types
  • Supports cold junction compensation (CJC) via terminal units equipped with temperature sensors
  • Hot-swappable architecture for online module replacement without system shutdown
  • ModuleBus communication interface for connection to S800 cluster adapters and controller nodes
  • Galvanic isolation between field inputs, logic, and power distribution rails
  • Configurable filtering and diagnostic reporting for open-circuit detection

Applications

  • High-accuracy temperature acquisition in chemical and petrochemical reactors
  • Thermocouple signal processing in power generation boiler and turbine monitoring
  • Millivolt transducer data collection in continuous process manufacturing lines
  • Distributed I/O expansion in ABB System 800xA process automation architectures

FAQ

What control systems are compatible with the ABB AI835 3BSE008520R1?
The AI835 module is designed for the ABB S800 I/O platform, integrating directly with ABB DCS architectures such as System 800xA via ModuleBus communication.

What input signal types does the AI835 support?
The module accepts thermocouple inputs across standard types (such as B, E, J, K, N, R, S, T) as well as low-level millivolt signals ranging from -150 mV to +150 mV.

Can the AI835 module be replaced while the system is powered?
Yes, the AI835 supports hot-swapping, allowing maintenance personnel to remove and replace the unit on an active S800 base plate without shutting down the entire control rack.

How is cold junction compensation handled for thermocouple inputs?
Cold junction compensation is handled externally via dedicated S800 terminal units equipped with integrated temperature sensors matched to the channel pairs.
