Installation Instructions
FX-PCX4711-x
Applications
The FX-PCX47 Expansion Input/Output (I/O) Module is
part of the Facility Explorer FX-PC Programmable
Controller family. The FX-PCX47 module expands the
number of inputs and outputs connected to FX-PCs to
monitor and control a wide variety of Heating,
Ventilating, and Air Conditioning (HVAC) applications.
The FX-PCX47 module operates on an RS-485
BACnet® Master-Slave/Token-Passing (MS/TP) Bus
and integrates into the Web-based Facility Explorer
system.
