WARNING! Install all equipment in accordance with the National
Electric Code and in a manner acceptable to the local authority
having jurisdiction. Read these instructions and the AXM
Installation & Operations Guide carefully before installing
equipment. Failure to follow all instructions may result in
equipment damage or a hazardous condition.
ATTENTION! Installez tout le matériel en conformité avec le
Code national de l'électricité et d'une manière acceptable pour
l'autorité localecompétente. Lisez ces instructions et le guide d'
installation et fonctionnement de l'AXM avant l'installation du
matériel. Le non respect des instructions peut entraîner desdes
dommages matériels ou une situation dangereuse.
Overview
Control the AXM with a VLX or ACM with a Dual Port
EIA-485 Option Card. AXMs can be combined with EXPs.
Fig. 1 Typical AXM (I/O expansion module), AXM-1048 shown.
Mount the AXM in a clean, dry, indoor location, out of direct
sunlight, and avoid excessive vibration and electrical noise.
Keep temp. between 32 deg. F–131 deg. F (0 deg. C–55 deg.
C) and relative humidity between 0-95%, non-condensing.
The AXM, VLX and ACM can be mounted in separate
enclosures if the enclosures are immediately adjacent and
the AXM communications bus runs in conduit that does not
contain any high-voltage wiring.
Mount the AXM in any vertical or horizontal orientation.
Use single-point grounding and separate 24 VAC power for
the BO loads to help ensure proper grounding.
Properly ground the panel, then terminate grounded
components of power, communications, and I/O wiring.
Power
Each AXM requires a 24 VAC, 50-60Hz, 20 VA minimum
power supply. Use a UL Listed transformer. VLXs, AXMs
and EXPs are half-wave devices so they may share an
appropriately sized transformer. Use a separate
transformer to power AXM and EXP BOs. AXM and EXP
power consumption ranges from 10 VA to 20 VA,
depending on the number and type of input devices
connected.
WARNING! The ACM is a full-wave device. All full-wave devices
must have a dedicated transformer.
WARNING! Half-wave and full-wave devices cannot share a
transformer or equipment damage will occur. If a VLX shares a
transformer with other devices, ensure all devices use a half-wave
rectifier.
WARNING! Do not share VLX/ACM/AXM/EXP power with any
VLC. VLCs require an independent 24 VAC power source.
WARNING! Do not connect 24 VAC terminals to ground or
equipment damage will occur. Maintain polarity of the power
connection among all devices sharing power.
Communications
AXMs communicate over a simple, twisted-pair
communications bus. Up to eight AXMs can connect to a
single global controller in a multi-drop configuration.
Universal inputs
Configure UIs to accept resistance (10K Ohm or 3K Ohm
thermistors or potentiometers), voltage (0-10VDC, 0-
5VDC), current (4-20mA), dry contact, solid-state switch
(transistor), or pulse-type inputs (IN-1, IN-2, and IN-3 only).
Outputs
Analog outputs support 4-20mA or 0-10VDC outputs.
Binary outputs; rated for 12VA (24VAC @ 0.5A). 20VDC
terminals can provide a power source up to 250mA total.

Installation
Mount the AXM on an EN50022 standard 7.5mm x 35mm
DIN rail or panel mount.
For DIN rail Mounting:
a. Holding the AXM with its top tilted in toward
the DIN rail, hook the two retaining tabs on the
back of the AXM onto the top of the DIN rail.
b. Push down and in to latch the two bottom
latching tabs of the AXM onto the DIN rail
—OR—
For Panel Mounting:
NOTE: The panel housing the AXM requires a ground bus that
connects to a suitable known ground. Ground the panel bus by
directly connecting to the closest point in the building’s electrical
service grounding electrode system.
a. Open the AXM cover.
b. Use the mounting holes in the back cover to
attach it to the panel with appropriate fasten-
ers (not included). See Fig. 2.
• To connect the AXM to a global controller:
1Remove power from the VLX/ACM/AXM.
2Connect AXM communications. Maintain polarity.
3Connect power to the VLX/ACM/AXM.

AXM BO power see Fig. 4.
Disposal
Electrostatic sensitivity
WEEE Directive 2012/19/EC Waste
Electrical and Electronic Equipment
directive
The product should not be disposed of
with other household waste. Check for the
nearest authorized collection centers or
authorized recyclers. The correct disposal
of end-of-life equipment will help prevent
potential negative consequences for the
environment and human health. Do not
burn this device.
The AXM and its components may be
susceptible to electrostatic discharge
(ESD). Use appropriate ESD grounding
techniques while handling the product.
When possible, always handle the product
by its non-electrical components.
