GENERAL INFORMATION
The AIM2 optically isolates an analog (voltage
or current) input signal from its
corresponding output signal. It will accept
any input signal between 0 and 20 VDC, or 0
and 20 mA, and output any signal within
those ranges. The AIM2 has preset or
adjustable inputs and preset or adjustable
outputs that can be either voltage or current.
The current signals on the input or output can
be either sink or source. The AIM2 requires
one external 24 VAC isolation transformer
with oating secondary for power. It has an
onboard 24 VAC isolation transformer to
supply power to the isolated output. The
AIM2 is eld calibratable, however, factory
calibration is available upon request for an
additional charge. This will speed up
installation time for the end user.
MOUNTING INSTRUCTIONS
Ground yourself to discharge static electricity
before touching any electronic equipment, as
some components are static sensitive. The
interface device can be mounted in any position. If circuit board slides out of snap track, a non-conductive
“stop”may be required. Use only ngers to remove board from snap track. Slide out of snap track or push
up against side of snap track and lift that side of the circuit board to remove. Do not flex board. Do not
use tools.
WIRING INSTRUCTIONS
PRECAUTIONS
• Remove power before wiring. Never connect or disconnect wiring with power applied.
• When using a shielded cable, ground the shield only at the controller end. Grounding both
ends can cause a ground loop.
• This device needs to have its own Isolated Transformer. This transformer cannot be
connected/or shared with any other device. It is recommended you use an isolated UL-listed class
2 transformer.
• All wiring must comply with all local and National Electric Codes.

The AIM2 is factory set as follows, unless otherwise specied: All DIP switches are set to OFF and will not
produce a proper signal output. Be sure to set switches to your required input and output ranges before
powering. See “SETTING AIM2 INPUT” below.
The AIM2 can be eld calibrated to your specications using the “adjustable” setting on the DIP switches.
See “SETTING AIM2 INPUT” below.
STEP 1) WIRING CONNECTIONS
With the power OFF, make the following connections:
Connect a 24 VAC power supply to the 24VAC terminals of the AIM2. Connect the input signal common (-)
to the COM input terminal of the AIM2, and the input signal positive (+) to the IN input terminal of the
AIM2.
Connect the output signal common (COM) and the output signal positive (OUT) to their respective
terminals on the controlled device.
SETTING AIM2 INPUT
DIP switches determine input ranges. Jumper block J2 is selectable for input voltage (E), current low 0 -
1mA (IL), or current high 0 – 20mA (IH) input signal. A current input can be either sinking or sourcing signal.
Explanation of “Source” and “Sink”:
Source – A signal where the positive (+) modulates and uses the negative (-) as the common. (Most
prevalent in the industry)
Sink – A signal where the negative (-) modulates
and uses the positive (+) as the common.
FOR PRESET VOLTAGE INPUT RANGES: Make
the following switch settings on input DIP switch.
Put Jumper J2 in (E) position (or Horz.) for voltage.
See Table 1.
FOR PRESET CURRENT INPUT RANGES: Make
the following switch settings on input DIP switch.
Put Jumper J2 in (IH) position for current. See
Table 2.

CALIBRATIONS OF INPUT SIGNAL OTHER THAN PRESETS SHOWN ON TABLE
1.) If you have an input range other than any presets shown above, set the input DIP switches to one of the
three Adj. settings. See inputs above in bold type.
2.) Apply the maximum of the input signal to terminals IN and COM. With a volt meter measure the voltage
from TP1 to the AIM2’s input side common (COM). Turn the input Max. pot until the meter reads 5.00 ± 0.00
V. The maximum of the input signal is now calibrated.
3.) If the minimum of the input signal is zero, set input DIP switches 7 and 8 OFF and 6 ON.
4.) If the minimum of the input signal is other than zero, set maximum as in step 2, and use the following
steps to set the minimum:
A.) Set switch 8 ON and 6 and 7 OFF.
B.) Produce the minimum signal value at the input terminal (IN).
C.) Measure the voltage between the TP1 test point and COM. Record or remember.
D.) Now measure voltage between the TP3 test point and COM. Adjust the input MIN pot until the
voltage at TP3 is equal to the voltage recorded at TP1. The minimum and maximum input signals are
now calibrated.
SETTING AIM2 OUTPUT
FOR PRESET VOLTAGE OUTPUT RANGES: Make the following switch settings on output DIP switches.
Set jumper J4 for E/Isnk (voltage/current sink), and J5 for SRC (source) output signal. See Table 3.
FOR PRESET CURRENT OUTPUT RANGES: Make the following switch settings on output DIP switch. If
Source, set Jumper J4 to I and J5 to SRC. If Sink, set J4 to E/Isnk, and J5 to SNK. See Table 4.
FOR CALIBRATION OF AN ODD OUTPUT SIGNAL
Before proceeding, you must have already set up the
input signal. If not, return to page 3 and “SETTING
AIM2 INPUT”.
Output ranges are selectable on the output DIP
switch by setting oset (minimum signal) and spans
available (maximum minus oset) are shown below.
Find out if you can use a preset range by subtracting
the minimum output signal (or oset) from the
maximum. For example, a 3.4 to 9.4 V signal output
equals a 6 volt range, which is available as a preset,
and the 3.4 volt oset can be adjusted. Any span not
listed below will have to be set from one of the
adjustable range switch settings.
TO SET PRESET OUTPUT SPANS (Reference only
switches 1 through 4, others are for OFFSET - See
Table 5).

TO SET ADJUSTABLE OUTPUT SPANS
If your output span is not a listed preset, set the span
DIP switches 1 through 4 to one of the three
adjustable ranges (just above in bold), and the oset
switches to the adjustable range by placing switch 8
ON, and 5,6,7 OFF. Give the AIM2 the maximum input
signal and adjust the SPAN pot until the required span is reached on the output terminals.
Three preset output signal osets are available. These will raise the entire span by the amount indicated,
above zero. For example, an 8V span with a 2V oset will give you a 2 – 10V output signal. If your oset (or
minimum output) is zero, set switch 5 ON and switches 6,7,8 OFF. See Table 6.
ADJUSTABLE OUTPUT OFFSETS
If your oset is not 0, 1, or 2 volts, you will need to adjust for your oset. The oset can be adjusted from 0
to approximately 10V.
Adjustable: 8 ON………………...5,6,7 OFF
Generate the minimum input signal at the input terminals IN and COM and calibrate the output OFFSET
pot until the oset required is reached (check with a voltmeter at output terminals OUT and COM).
From this point on, no further DIP switch changes are necessary. Toggle back and forth between the
maximum and minimum to check the accuracy of the calibration. If the span (or maximum of the output)
needs adjustment, turn the span pot. If the oset (or minimum) needs adjustment, turn the oset pot.
Repeat until calibrated correctly.
POWER UP AND CHECKOUT
STEP 2) POWER UP
Turn on the 24 VAC power supply. Both power indicators on the AIM2 will light.
STEP 3) OPERATION
The AIM2 will now operate to your specications, or the standard settings from the factory. If no eld
calibrations were made, then the AIM2 will accept a 0 to 5 volt DC input signal and produce an isolated and
proportional 0 to 5 volt DC output signal. For example, a 3.50 volt input signal will produce a 3.50 volt DC
output signal.
