An RTD Input block has six input circuits, in three groups of twocircuits each. Group to group isolation is 300 volts. Each input can be used with platinum, nickel, or copper RTDs. Input data for each circuit is linearized according to the type of RTD selected. Input data is reported to the CPU in engineering units of tenths of degrees Celsius, tenths of degrees Fahrenheit, tenths of Ohms, or counts.Additional configurable features include:- Alarm thresholds- RTD resistance- Alpha type- Linearization- Input filter time
