Infilex™GC 
Multipurpose Controller 
Model WY5311 
 
General 
Infilex GC (Infilex: named for “Infinity” and “Flexible”) Model 
WY5311 is a multipurpose controller designed to control 
building equipment, such as air handling unit (AHU). Infilex 
GC enables to control the temperature and humidity, as well 
as building equipment operation. 
Infilex GC can be operated with a user terminal and with 
Operator Panel. Besides, Infilex GC can communicate with 
BMS (building management system) Azbil Corporation’s 
savic-net™FX via LonTalk®protocol. By sending the 
operation status to the main control unit (monitoring 
computer) and by controlling the operation based on the 
commands sent from the main control unit, the integrated 
control of the entire building can be executed. 
Infilex GC consists of a basic unit and connectable I/O 
modules (and a user interface module). The number and 
types of the modules can be flexibly changed corresponding 
to the control or management to fit in various applications. 
Additionally, since the software to be installed can be freely 
edited, an optimum application for building equipment can be 
configured in terms of both the software and hardware. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Features 
•Compact design: 
Small size body allows free installation in a desired 
place. 
•Various input/output (I/O) configurations: 
Input and output types can be selected, and the number 
of points to be mounted can be increased or decreased 
corresponding to the application. 
•Editable software configurations: 
Optimal software for the contents of the application can 
be configured. 
•User interface module (Operator Panel): 
Operator Panel (panel mount type/integral type) 
connected to Infilex GC allows you, without changing the 
settings from the BMS center unit, to change the Infilex 
GC settings. 
•Remote control with a user terminal: 
Neopanel™or Neoplate is connectable, so that a user at 
a remote location can perform ON/OFF operation and 
change temperature setting. 
 
 
•Autonomous distributed control: 
Even if a trouble occurs in the BMS, the backup 
operation is performed individually to distribute potential 
risks caused by malfunction of the system. 
•Installation: 
A quick-fit screwless (clamp) terminal block is used for 
the communication terminal block of the I/O module, 
ensuring the labor saving of the wiring work. 
Additionally, either DIN rail mounting or screw mounting 
can be selected. 
•L
ONMARK®certified product: 
Infilex GC is LONMARK®certified and thus interoperable 
integrated in the LONWORKS®system. 
•CE Marking certified product: 
Infilex GC conforms to all the applicable standards of CE 
Marking (Class A).
