FAQ

Q1: What is the main purpose of the AI950S module?
A: It is used to collect and condition temperature signals from field sensors for ABB control systems.
Q2: Why use a temperature-specific input module instead of a standard analog input?
A: Temperature signals require higher stability and dedicated conditioning. A specialized module delivers more reliable results.
Q3: Does replacing the module require complex recalibration?
A: In most ABB systems, only basic channel verification is required after replacement.
