FX-PCX47 Expansion Input/Output Module Installation
Instructions
Part No. 24-10144-122, Rev. DFX-PCX4711-x
Issued December 5, 2014
Refer to the QuickLIT website for the most up-to-date version of this document.
Application
The FX-PCX47 controller is part of the Facility Explorer
FX-PC Series Programmable Controller family. FX-PCX
controllers expand the number of points connected to an
FX-PCA, FX-PCG, or FX-PCV programmable controller
or to a supervisory controller.
FX-PCX47 controllers operate on an RS-485 BACnet®
Master-Slave/Token-Passing (MS/TP) Bus as BACnet
Application Specific Controllers (B-ASCs) and integrate
into Johnson Controls® and third-party BACnet systems.
Note: At FX-PCT Release 10.1, a new capability was
introduced allowing FX-PCVs, FX-PCGs, and
FX-PCAs to communicate by using either the
BACnet or the N2 field bus networking protocol.
The operation of the FX-PCX Input/Output Module
is not affected by the selection of the BACnet or
the N2 protocol in the host controller.
North American Emissions
Compliance
Canada
This Class (A) digital apparatus meets all the
requirements of the Canadian Interference-Causing
Equipment Regulations.
Cet appareil numérique de la Classe (A) respecte toutes
les exigences du Règlement sur le matériel brouilleur
du Canada.
United States
This equipment has been tested and found to comply
with the limits for a Class A digital device pursuant to
Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful
interference when this equipment is operated in a
commercial environment. This equipment generates,
uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction
manual, may cause harmful interference to radio
communications. Operation of this equipment in a
residential area may cause harmful interference, in which
case the users will be required to correct the interference
at their own expense.
Installation
Observe these guidelines when installing a controller:
• Transport the controller in the original container to
minimize vibration and shock damage.
• Verify that all parts shipped with the controller.
• Do not drop the controller or subject it to physical
shock.
Parts Included
• one controller with removable terminal blocks (Power,
SA, and FC bus are removable)
• one installation instructions sheet
Materials and Special Tools Needed
• three fasteners appropriate for the mounting surface
(M4 screws or #8 screws)
• one 20 cm (8 in.) or longer piece of 35 mm DIN rail
and appropriate hardware for DIN rail mount (only)
• small straight-blade screwdriver for securing wires in
the terminal blocks
Mounting
Observe these guidelines when mounting a controller:
• Ensure the mounting surface can support the
controller, DIN rail, and any user-supplied enclosure.
• Mount the controller horizontally on 35 mm DIN rail
whenever possible.
• Mount the controller in the proper mounting position
(Figure 1).
• Mount the controller on a hard, even surface
whenever possible in wall-mount applications.
• Use shims or washers to mount the controller securely
and evenly on the mounting surface.
• Mount the controller in an area free of corrosive
vapors and observe the Ambient Conditions
requirements in Table 10.
• Provide for sufficient space around the controller for
cable and wire connections for easy cover removal
and good ventilation through the controller (50 mm
[2 in.] minimum on the top, bottom, and front of the
controller).
