ABB AI835

  • System Compatibility: Ensure any replacement analog input module is compatible with your S800 controller and uses the same communication protocol.
  • Project Requirements: If you’re working on a new project, explore ABB’s current offerings within the S800 I/O series to find a module that meets your specific needs in terms of the number of channels, temperature range, voltage range, and any additional features you might require.
  • Modernization: Newer modules might offer improved features like higher resolution, better accuracy, or advanced diagnostics capabilities compared to the AI835.

I can also help you search for datasheets or user manuals for the AI835 from ABB’s website, authorized distributors, or third-party sources. Do you have any specific questions about using or replacing the ABB AI835?

Description

Based on our previous discussions and information gleaned from web searches, the ABB AI835 appears to be an 8-channel analog input module designed for thermocouple (TC) and millivolt (mV) measurements within ABB’s industrial automation systems, specifically for the S800 I/O series. Here’s a summary of its functionalities:

  • Function (Analog Input Module):

    • The AI835 is designed to acquire temperature or voltage signals from sensors connected to its eight input channels.
    • It supports various thermocouple types (B, C, E, J, K, N, R, S, T) and a linear voltage range of -30 mV to +75 mV for millivolt measurements.
    • The module converts these analog signals into digital data that can be processed by an S800 controller within the automation system for monitoring and control purposes.

  • Applications (Within ABB S800 I/O Systems):

    •  
    • The AI835 would have been used in various industrial automation applications requiring temperature or low-voltage measurements, such as:
      • Factory automation (monitoring machine temperature, process control).
      • Power generation and distribution (monitoring transformer temperature, voltage levels).
      • Building automation systems (HVAC control, monitoring environmental conditions).
      • Industrial furnaces and ovens (temperature control).

  • Availability (Potentially Still Available):

    • Unlike some of the previously discussed modules, the AI835 might still be available because it’s part of the S800 I/O series. You can check ABB’s website using the part number (AI835) or browse their S800 I/O product categories.
    • Even if ABB doesn’t directly sell it anymore, you might find new or used units through:
      • Authorized ABB distributors.
      • Online marketplaces (verify seller reputation before purchase).

Here’s how I can assist you with the ABB AI835:

  • Using an Existing AI835:
    • If the AI835 is functioning properly in your existing S800 system, you might not need to replace it immediately.
  • Looking for a Replacement or for a New Project:
    • Check ABB’s website or authorized distributors for the current availability of the AI835 or compatible replacements within the S800 I/O series.
    • Consider contacting ABB support to inquire about the AI835’s compatibility with your specific needs and for recommendations on replacements if necessary.

Additional Considerations:

  • System Compatibility: Ensure any replacement analog input module is compatible with your S800 controller and uses the same communication protocol.
  • Project Requirements: If you’re working on a new project, explore ABB’s current offerings within the S800 I/O series to find a module that meets your specific needs in terms of the number of channels, temperature range, voltage range, and any additional features you might require.
  • Modernization: Newer modules might offer improved features like higher resolution, better accuracy, or advanced diagnostics capabilities compared to the AI835.
