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.
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?
