InfilexGC 
Multipurpose Controller 
Model WY5111 
 
General 
Infilex GC (Infilex: named for “Infinity” and “Flexible”) Model 
WY5111 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 consists of a basic unit and I/O modules, UT 
module, integral type Operator Panel, and SAnet interface 
module. The number and types of the modules can be 
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 is configured in terms of both the software 
and hardware. 
Infilex GC is operated with a user terminal and with Operator 
Panel to correspond with various situations. Besides, Infilex 
GC communicates with Azbil Corporation’s savic-net
 FX 
BMS through the transmission trunk line called NC-bus. By 
sending the operation status to the BMS center unit or by 
controlling the operation based on the commands sent from 
the BMS center unit, the integrated control of the entire 
building can be performed. Azbil Corporation’s field devices, 
Intelligent Component Series devices, are also connectable to 
Infilex GC via SAnet, allowing high-performance control. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Features 
Compact design: 
Small size body allows free installation in a desired place. 
I/O module 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 configuration: 
Optimal software for the contents of your 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 in a 
room (remote location) can perform ON/OFF operation 
and change temperature setting. 
 
Cooperation with BMS: 
Infilex GC integrated into savic-net FX enables to 
centrally monitor and control building equipment from the 
BMS center unit (client PC). 
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 for the 
communication line reduces wiring work load. 
Additionally, either DIN rail mounting or screw mounting 
can be selected. 
Connection to Intelligent Component Series devices: 
Intelligent Component Series devices offering advanced 
control are connectable via SAnet. 
CE Marking certified: 
Infilex GC Model WY5111W0000 (NC-bus model (Line 
A)) conforms to all the applicable standards of CE 
Marking (Class A).
