Control system diagrams use standard symbols to describe the component function required for the system to achieve its intended control functions. Standard symbols are used to allow engineers to describe the logic and component functions. Define the function of symbol "I" as shown in the illustration. See Illustration GS-0180

Accepted Answer

Option C: Low Select Signal Processor.. In control system logic, the symbol 'I' typically denotes a Low Select function. This component compares multiple input signals and transmits only the lowest value to the controller, which is a common safety and operational strategy used to prevent process variables from exceeding safe minimum or maximum limits.
