Analogue Inputs and Spanning
The MSC-3 analogue inputs have been designed with the following features:
• Congurable voltage (V) or current (mA) input conguration.
• Easy to congure spanning and translation.
• High and Low compare logic outputs with adjustable thresholds
• The diagram below illustrates the design:

Reference is clamped beyond the range of G023 and G024.
Key conguration parameters are:
• G020 AN IN mode
• G021 MIN input and G022 MAX input
• G023 REF @MIN in and G024 REF @MAX in
• G025 HiCMP Level and G026 LoCMP Level
