MODEL IAMA - CONFIGURABLE 3-WAY ISOLATING AMPLIFIER
GENERAL DESCRIPTION
The IAMA can isolate and convert over 35 combinations of analog signal
ranges. The IAMA converts and transmits signals linearly proportional to the
input. 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 35 standard signal conversions. In addition to the
conversion capabilities, the IAMA modules feature optically isolated
Input/Output signal circuits and isolated Power to Input, Power to Output
circuits. The modules' overall full scale accuracy typically exceed 0.04%. DIN
rail mounting saves time and panel space. The units are equipped with universal
mounting feet for attachment to standard top hat profile rail according to
EN50022 - 35x7.5.

The IAMA converts and transmits signals linearly proportional to the manual or on equipment must be observed to ensure personal safety and to input. - Page 2 15. TESTS/APPROVALS: INPUTS The IAMA accepts a full range of process signal inputs and isolates and converts these signals to common industrial control signals. The input signal PROCESS CONTROL EQUIPMENT FOR combinations are configured by making specific DIP switch selections on the 6 HAZARDOUS LOCATIONS and 2 position DIP switches.
- Page 3 The IAMA’s universal input allowed for easy signal conditioning of the various output signals to the required PC’s Bus Board 0 to 10 VDC input signal. In this case, the IAMA’s re- transmitted 0 to 10 VDC output was field calibrated, negating the expense and time required to rewrite the PC’s software...
