MODULE ISOLATION
combination of optical and transformer isolation. The optical isolation provides
common mode voltage (CMV) isolation up to 1.5 kV between the sensor input and
the process signal output. The IAMA’s power is isolated from the sensor signal
input and the process signal output by a DC/DC transformer isolation circuit.

OVERVIEW
provides a linearly proportional voltage or current output, while the IAMA6262
transmits the scaled square root of the input signal. This allows the IAMA6262
to provide a signal that is linear to flow rate in applications utilizing a differential
pressure transducer. Both units have two modes of operation known as Factory
and Field modes. Factory mode is used when the default input and output ranges
are suitable. Field mode can be independently selected for both the input and
output, and allows the user to custom calibrate, or scale the signal. If Factory
mode is selected, the IAMAs use factory presets for the selected input or output
range. If Field mode is selected, the IAMAs can be custom scaled within a
selected input or output range. Field mode also allows the IAMA to reverse its
output in relation to its input.

factory checksum error occurs. See Factory Recalibration for details. Field
scaling is achieved by applying minimum and full scale values from a
calibration source and storing the values by a single DIP switch transition. Field
scaling is available for all input and output ranges and the values are permanently
stored in E
modes for a particular range, which restores the respective setting. The Factory

extent of the selected range. The closer together the minimum and full scale
values are to each other, the less accurate the signal will be. For example, if the
0 to 1 V input range is selected, and the unit is scaled for 0 to 0.5 V, the signal
has the same resolution as the 0 to 1 V range. Since this resolution will be two
times the percentage of span for 0.5 V, more accuracy can be achieved by using
the 0 to 0.5 V range.

circuits from wiring errors and transient high voltage conditions.
INPUTS

combinations are configured by making specific DIP switch selections on the 10
position DIP switch.
OUTPUTS

transitioning S1-2 to store that value. Next, the full scale value is applied and the
DIP switch transition stores the value. The output scaling is performed in a
similar manner but the output is driven to the desired minimum and full scale
values by the calibration source applied to the input. S1-1 is used to store the
minimum and full scale output values.

removed and valid ranges selected for the IAMA to operate properly.
