Installation & Operation Instructions
AIM1.1

GENERAL INFORMATION
The AIM1.1 optically isolates an analog (voltage or
current) input signal from its corresponding
output signal. The factory calibrated output is
linear and proportional (1:1 ratio) to the input
signal. The AIM1.1 will accept a 0 to 5 VDC, 0 to 10
VDC, or 0 to 20 mA input span and output any one
of those same ranges. It requires one external 24
VAC isolation transformer with oating secondary
for power and has an onboard 24 VAC isolation
transformer to supply the isolated output.
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
ex 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.
FUNCTION SELECTIONS
STEP 1) INPUT TYPE
Set jumper block J1 for 0 – 5 Volts, 0 – 10 Volts, or 0 – 20 milliamps input signal. See Figure 3 (p. 2) for
details.
STEP 2) OUTPUT TYPE
Set jumper block J2 and J3 for 0 -5 Volts, 0 – 10 Volts, or 0 – 20 milliamps output signal. See Figure 3
(p.2) for details.

Calibration and Checkout
The AIM1.1 is factory calibrated as follows, unless otherwise specied: 0 – 5 Volts Input Signal 1:1 Input to
Output Signal Ratio, 0 -5 Volts Output Signal.
STEP 3) WIRING CONNECTIONS (for“source”input and output)
With the power OFF connect a 24 VAC power supply to the 24VAC terminals of the AIM1.1.
For inputs from powered current devices, and voltage input signals, connect signal common (-) to the I3
signal input terminal of the AIM1.1, and the signal positive (+) to the I2 signal input terminal of the AIM1.1.
For 2-Wire current inputs to AIM1.1 requiring power see Figure D on page 2 for hook-up details.
Connect the output signal common (-) terminal O3 and the output signal positive terminal O2 to their
respective terminals on the controlled device.
For current “sink” output from AIM1.1, see Figure E on page 2 for hook-up details.
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.
STEP 4) POWER UP
Turn on the 24VAC power supply. Both Primary Power (PRI POWER) and Secondary Power (2ND POWER)
LED indicators on the AIM1.1 will light.
STEP 5) OPERATION
The AIM1.1 will now accept an input signal and produce an isolated and proportional output signal.
(Example, a 5.0 volt input signal will produce a 5.0 (± 0.05 volts) volt DC output signal.)
