GENERAL DESCRIPTION
The IAMA – Universal Signal Conditioning Module Series can isolate and
convert over 100 combinations of analog signal ranges. The IAMA3535
converts and transmits signals linearly proportional to the input, 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 trasducer.
DIP switch range selection eliminates the need to order and stock different
modules for each input and output signal range, and allows quick and
convenient setup for over 100 standard signal conversions. By utilizing the
Field mode of calibration, the user can customize the input and output scaling
for odd applications, including reversal of the output relative to the input.
In addition to the conversion capabilities, the IAMA modules feature
optically isolated Input/Output signal circuits and transformer isolated Power to
Input, Power to Output circuits.
The modules’ overall full scale accuracy typically exceed 0.05% depending
upon range selection and scaling. The microprocessor based design provides
ease of field scaling and the onboard E
2
PROM stores scaling values for future
recall. Both models come factory precalibrated for all input and output ranges.
Factory or custom field scaling can be selected by a simple mode switch change.
The IAMA can be factory recalibrated in the field if desired.
The modules’ environmental operating temperature range is -20
°
C to +65
°
C.
DIN rail mounting saves time and panel space. The units are equipped with
universal mounting feet for attachment to standard DIN style rails, including top
hat profile rail according to EN50022 - 35x7.5 and 35 x 15 and G profile rail
according to EN50035-G32.
SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in the
manual or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
