Analog Inputs
Each Analog Input Block (AI) can accept one external analog signal as an input
and produces one analog output, Value. The type of input – current or voltage
signal and single-ended or differential – is selected by jumpers at the rear of the
unit. Each block converts the signal applied to the terminals of the controller to a
floating point value. All the required scaling and calculation is done within the
block. The output Val ue is in the range 0.0 to 1.0 which corresponds to 0 to 100%
of the input. Each block also holds the parameters Mode, RootExtraction,
FilterTime, Alarm, Loop and Identity.
Note: The Loop parameter is only available on the ECA600.
