Multiple Input Ranges
The 1756-IRT8I module offers multiple input ranges. The input type and sensor
type selections determine the available ranges.
The following table describes this module’s input ranges in relation to the sensor
type. If a single range is listed in the Input Range column, the programming
application automatically selects the range used with the previously listed
sensor type.
To see where to select the input range, see page 127
.
