Description
The code AI830A refers to an RTD Input Module manufactured by ABB for use in their S800 I/O (Input/Output) systems. Here’s a breakdown of the information to help you understand its function:
Function:
- The AI830A module is designed to measure temperature using Resistive Temperature Devices (RTDs). RTDs are sensors whose electrical resistance changes predictably with temperature variations.
- The AI830A measures the resistance of connected RTDs and converts it into a digital signal that the S800 I/O system can understand.
- This digital temperature data can then be used by a control system for monitoring, process control, or alarm generation.
Features (Possible):
While detailed specifications might be limited for older models, the AI830A likely offers features like:
- Multi-channel input: The “8” in AI830A suggests it can handle 8 RTD inputs simultaneously.
- Configurable temperature range: The module might allow setting the acceptable temperature range for each RTD input.
- Cold junction compensation: This compensates for temperature variations at the connection point between the RTD and the module, ensuring accurate temperature measurements.
Applications:
The AI830A RTD Input Module is likely used in various industrial automation applications requiring precise temperature measurement and control, such as:
- Process industries: Chemical plants, oil refineries, and other facilities can use the AI830A to monitor temperatures in reactors, pipelines, and other equipment.
- Power generation: Temperature monitoring in power plants for critical components like transformers, turbines, and cooling systems.
- Building automation: HVAC (Heating, Ventilation, and Air Conditioning) systems can leverage the AI830A to regulate temperature in buildings.
Finding Information:
-
ABB Website: Search for “AI830A” or “S800 RTD Input Module” on the ABB websiteWhile information for older models might be limited, you might find product pages for similar current models or user manuals with general RTD input module functionalities.
-
Alternative Resources: Search online resources related to ABB S800 I/O systems and RTD temperature measurement. You might find:
- Datasheets for similar current ABB RTD input modules

-
Contact ABB Support: If you require specific details or have questions about the AI830A, contacting ABB support can be helpful. They can advise on alternative resources or suggest compatible replacements if the AI830A is no longer actively supported.
Additional Considerations:
- Compatibility: When replacing the AI830A, ensure the new module is compatible with your existing S800 I/O system in terms of:
- Physical dimensions and mounting requirements
- Communication protocols
- Voltage and current requirements
By understanding the function of the ABB AI830A and using these suggestions, you can effectively maintain or upgrade your industrial automation system for temperature measurement applications.
