Specifications/Instructions
Infilex™AC
AHU Controller
Model WY5317C
General
Infilex AC (Infilex: named for “Infinity” and “Flexible”) Model
WY5317C is a DDC (direct digital control) controller for AHU
(air handling unit). It can be placed in a small place such as
an AHU control panel.
Infilex AC is equipped with inputs and outputs suitable for
AHU control, and its software can be freely edited in
response to the applications.
In terms of operation, Infilex AC can be operated with a user
terminal (Neopanel™/ Neoplate) or Operator Panel to
correspond with various situations. Besides, it performs
advanced control and management by communicating with
BMS (building management system) savic-net™FX via
LonTalk®protocol. Infilex AC integrated into BMS enables
autonomous control since Infilex AC itself has the time
scheduling function.
Features
•Compact design:
Small size body can be fit into a control panel of a
compact AHU unit.
•Various input/output (I/O) configurations:
Model number changes depending on the number of its
I/O points, which allows external cooling control,
humidification, and other AHU controls.
•User interface module (Operator Panel):
Operator Panel (panel mount type/integral type)
connected to Infilex AC allows you, without changing the
settings from the BMS center unit, to change the Infilex
AC 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 center unit, the
backup operation is performed individually to distribute
potential risks caused by malfunction of the system.
•I/O module:
To Model WY5317C0400, one I/O module can be added
so that the number of I/O points is increased.
•Cooperation with BMS:
To perform advanced control and management, Infilex
AC can directly communicate with the BMS center unit
(savic-net™FX client PC).
•Installation:
Quick-fit screwless (clamp) terminal blocks are used for
the I/O terminal block, ensuring the labor saving of the
wiring work.
Additionally, a desired mounting method can be selected
from two kinds of mounting methods, DIN rail mounting
and screw mounting.
•CE Marking certified product:
Infilex AC conforms to all the applicable standards of CE
Marking (Class A).

reference.
Usage Restrictions
This product is targeted for general air conditioning. Do not use this product in a situation where human life may be affected. If
this product is used in a clean room or a place where reliability or control accuracy is particularly required, please contact Azbil
Corporation’s sales representative. Azbil Corporation will not bear any responsibility for the results produced by the operators.
WARNING
•DANGER: To prevent the risk of severe or fatal electrical shock, always disconnect power source and product
power supply before performing any wiring.
•Be sure to ground with 100 Ωor lower ground resistance. Improper grounding may cause electrical shock or
equipment damages.
•Do not detach the terminal cover at any time except when wiring. After wiring, be sure to attach the terminal cover.
Before attaching/detaching the terminal cover, make sure that the wires are not current-carrying to prevent
electrical shock.
•Disconnect power before the product replacement to prevent electrical shock.
•Wire strip length to be connected to the quick-fit screwless terminal block must be 8 mm. If the strip length is longer
than 8 mm, the conductor will be exposed, causing electrical shock or short circuit between adjacent terminals. If
it is shorter, the conductor will not contact the connector.
•Do not disassemble the product. Disassembly may result in electrical shock or equipment damage.
CAUTION
•Installation and wiring must be performed by qualified personnel in accordance with all applicable safety
standards.
•Installation must be carried out according to the operating conditions (power, temperature, humidity, vibration,
shock, installation position, atmospheric condition, etc) specified in this manual to prevent equipment damages.
•All wiring must comply with local codes of indoor wiring and electric installation rules.
•Install a circuit breaker or circuit protector in the power supply circuit that supplies the power to the product.
•Use crimp terminal lugs with insulation for electric wires connected to the screw terminals.
•Connect cables to the power source with terminals or the like for permanent connection.
•Make sure all the wires are tightly connected to prevent heat generation or equipment damages.
•If more than the rated power supply voltage is applied, product replacement is required for safety.
•Install this product in a location out of reach of unauthorized people. (e.g. Inside of the control panel cabinet)
•Lightening protection based on the regional characteristics and the building structure is needed to minimize
equipment damages.
•Noise protection is necessary when the product is installed in a location close to many noise sources.
•Do not block the vent holes of the product to prevent equipment damages. Remove protective sheet after
installation and wiring.
•After mounting the product on DIN rail, make sure that the holding parts of all the modules are properly fixed with
their whole parts lifted. The product may drop from the DIN rail and be damaged due to improper mounting.
•Dispose of the lithium battery in accordance with your local regulations.
•Dispose of this product in accordance with your local regulations. Do not reuse all or a part of this product.

Notes
∗M3 screw terminal block is provided for wiring of power supply and ground. Crimp terminals therefore are required for the cable ends.
∗Quick-fit screwless terminal blocks are provided for the wiring of communication and I/O. The wires can be connected only by stripping the
sheath. (Sheath stripped length: 8 mm, pin terminal cannot be used.)
∗Organize the cables with cable binding bands so as not to hide LED, battery holder, or tag.
∗JIS: Japanese Industrial Standards
∗KPEV is a wiring standard provided by Furukawa Electric Co., Ltd.
∗JCS: Japanese Electric Wire and Cable Makers’ Association
∗System common: Ground line (⊥) is used as a common line for signal (-) transmission. Actuator/damper thus has to have mutual ground as
the connected Infilex AC.
When the valve/damper is connected for the system common, the valve/damper operating current flows through the common line. Hence,
the specification is as shown above, For a 20-m-long IV 1.25 mm2cable, use 4 wires for connections to prevent the operating current from
flowing through the common line.

For the specifications of I/O modules and user interface modules, refer to Specifications/Instructions of Model RY50XX
(AB-6527). For the specifications of Operator Panel (integral type / panel mount type), refer to Specifications/Instructions of
Model RY5001Q/QY5100W (AB-6546).
