Application
The FX-PCX47 controller is part of the Facility Explorer
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
Controllers (B-ASCs) and integrate into Johnson Controls
Note: At CCT Release 10.1 and later, 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 I/O can be connected through the SA bus to a host controller that is using
either the BACnet or the N2 protocol. Only the BACnet protocol is supported when the I/O is
connected directly to the trunk using the FC bus.
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 and SA/FC bus are removable)
• One installation instructions sheet

Summary of Contents for Johnson Controls FX-PCX47

  • Page 1 FX-PCX47 Expansion Input/Output Module Installation Instructions 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.

  • Page 2: Materials And Special Tools Needed

    • Do not mount the controller in areas where electromagnetic emissions from other devices or wiring can interfere with controller communication. Observe these additional guidelines when mounting an FX-PCX47 controller in a panel or enclosure: • Mount the controller so that the enclosure walls do not obstruct cover removal or ventilation through the controller.

  • Page 3: Din Rail Mount Applications

    Mounting the controller horizontal on 35 mm DIN rail is the preferred mounting method. To mount an FX-PCX47 controller on 35 mm DIN rail: Securely mount a 20 cm (8 in.) or longer section of 35 mm DIN rail horizontal and centered in the desired space so that the controller mounts in the horizontal position shown in Figure 1.
  • Page 4 (or anchors). Carefully tighten all of the screws. Important: Do not overtighten the mounting screws. Overtightening the screws may damage the mounting clips.
