Application
The FX-PCX17 and FX-PCX27 Expansion Input/Output Modules are part of the Facility Explorer
PC Series Programmable Controller family. FX-PCXs expansion modules expand the number of I/
O points connected to an FX-PCA, FX-PCG, or FX-PCV programmable controller or to a supervisory
controller.
The FX-PCX controllers operate on an RS-485 BACnet
Controls
and third-party BACnet systems.
®
Note: At Controller Configuration Tool (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 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 an FX-PCX 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.
