GENERAL INFORMATION
The 6N1-ISO-STG series is a microprocessor
controlled interface designed to provide maximum
exibility with a minimum of cost.
With a variety of standard inputs, the 6N1-ISO-STG
provides the user with the ability to interface
several devices to a single analog output.
The 6N1-ISO-STG is a true staging device. It can be
used in retrot applications of interfacing a two or
three stage thermostat to an SCR heater. It will
convert 24VAC staged signals to a proportional
analog output. The 6N1-ISO-STG oers two
dierent modes. The rst mode will check inputs
sequentially high(#6) to low(#1), to set output
percentage. The output percentage is based on
highest input pressed, and ignores others. The
other mode will check the total number of inputs,
to set an output percentage. The output
percentage is based on total number of active
inputs.
Input ranges are jumper selectable and all modes
and analog outputs are DIP switch selectable. The
output signal is optically isolated from the input
signals. The power output terminal can be used for
power if the inputs are only contact closures.
MOUNTING INSTRUCTIONS
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 or use tools.
WIRING INSTRUCTIONS
PRECAUTIONS
• 6N1-ISO-STG is powered by 24 VAC only.
• 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.
Note: ACI recommends to remove the pluggable terminal blocks to terminate wires rst. The terminal
blocks can be removed using pliers. Once wired, rotate the terminal block 90 Degrees so they are facing
upward, and insert onto pins.This eliminates any wires getting pinched by the snaptrack. See Figure 4 (p.3).

Wiring Connections
Connect Input Signal Common (-) to terminals
labeled (-) labeled AI1 thru AI6.
Connect Input Signal (+) to respective terminal (+)
labeled AI1 thru AI6.
Connect controlled device to SIG OUT (+) and (-).
Connect 24 VAC to terminals marked 24 VAC (+) and
(-). See Figure 2 (p.2).
Operation
The 6N1-ISO-STG can:
Fan Mode #1
Check inputs sequentially high(#6) to low(#1), to
set output percentage. The output percentage is
based on highest input pressed, and ignores
others. This is based on the Input # priority.
Example #1: 4 Inputs used, 0-10VDC output
Activate Input #3. Output = 7.5VDC (3/4 = 75%)
Example #2: 6 Inputs used, 0-10VDC output
Activate Input #4. Output = 6.6VDC (4/6 =
66.6%)
Fan Mode #2
Check total number of inputs, to set output
percentage. The output percentage based on
total number of inputs active.
Example #1: 4 Inputs used, 0-10VDC output
Activate Input #1 and #3. Output = 5VDC
(50%)
Example #2: 4 Inputs used, 0-10VDC output
Activate Input #3. Output = 2.5VDC (25%)
Example #3: 6 Inputs used, 0-10VDC output
Activate Input #1, #4, #5, #6. Output = 6.6VDC
(4/6 = 66.6%)
CALIBRATION, JUMPER & DIP
SWITCH SETTINGS
The 6N1-ISO-STG output is factory calibrated in
all four DIP switch selectable output ranges. Do
not adjust the potentiometers on the
6N1-ISO-STG as this may void any warranty.
