The ABB AI835A (3BSE051306R1) is a high-precision analog input module within the S800 I/O series, specifically engineered for thermocouple and millivolt signal acquisition. Designed for integration with the ABB Ability System 800xA, this module provides 8 differential input channels, offering versatile configuration for process temperature monitoring and linear voltage measurement.

Features

  • 8 differential input channels supporting mV and various thermocouple types (B, C, D, E, J, K, L, N, R, S, T, U).
  • Configurable measurement range: -30 mV to +75 mV linear.
  • 15-bit A/D resolution for high-accuracy signal conversion.
  • Channel 8 can be dedicated to Cold Junction (CJ) compensation via Pt100 RTD or configured for standard input use.
  • Integrated wire-break and open-circuit monitoring for enhanced diagnostic reliability.
  • Groupwise isolation from ground.

Applications

  • Power Generation: Monitoring turbine exhaust gas temperatures and boiler heat levels.
  • Chemical Processing: Precision tracking for reactor vessels, fluid lines, and distillation columns.
  • Oil & Gas: Reliable data acquisition for remote extraction sites and refinery process loops.
  • Metallurgy: Temperature management in furnaces, casting, and curing processes.

Installation Guidelines

  • Ensure the system power is completely disconnected before mounting or removing the module from the MTU (Module Termination Unit).
  • This module is designed for standard S800 I/O rack mounting; verify that the MTU is correctly seated and locked.
  • Maintain proper shielding for field cables to minimize electromagnetic interference, keeping signal runs under the 600-meter limit.
  • Handle with standard ESD precautions to prevent damage to sensitive internal components.
  • When using Channel 8 for Cold Junction compensation, ensure the Pt100 RTD is correctly wired to the designated MTU terminals.

FAQ

What type of thermocouple sensors are compatible with the AI835A?

The module supports a wide range of industry-standard thermocouples, including types B, C, D, E, J, K, L, N, R, S, T, and U.

Can Channel 8 be used for standard measurements?

Yes. While Channel 8 is typically configured for Cold Junction temperature compensation, it can be utilized as a standard input channel if CJ compensation is managed via a fixed user parameter or an external source.

Is this module compatible with HART communication?

No, the AI835A does not support HART protocol or Sequence of Events (SOE) time-tagging.
