FX2NC Series Programmable Controllers Introduction 1.

1.5.3 Rules

1) Add the input/output points of the extension blocks and special functions blocks to the input/

output points of the main unit. The total number of input points should be 184 points or less,
and the total number of output points should be also 184 points or less. The total number of
input and output points should be no more than 256 points.

2) The FX

2NC

series main unit supplies the control power (5V DC) to the extension blocks and
special function blocks. For this reason, the total current consumption of all the blocks con­nected to the main unit should not exceed the current capacity of the main unit.

3) Next to the FX
unit, such as the FX

2NC

-CNV-IF, up to 4 blocks can be connected. To connect a special function

2N

-10GM or FX2N-1RM-E-SET, refer to the instruction manual of the cor-

responding special function block.

Calculation form for system configuration

Enter current consumption values and input/output points of the extension blocks and special
function blocks while referring to Sec. 1.5.2, and then calculate the total current value r and
total input and output points s through v. From the obtained values, judge whether the blocks
can be connected.

1.5.5 Quick judgment

To connect FX

2NC

series extension blocks only, use the following tables to quickly obtain the

connectable input/output points.

Example of quick judgment:

2NC

• If 96 input points are connected to the FX

-32MT-D/UL main unit, up to 112 output points

can be connected.

• If the number of output points are determined first, select the same number or a slightly
larger number from the output points (Y) area (area marked with *1). In this case, note that
you cannot increase the corresponding number of input points shown above even if the
determined number of output points is slightly smaller than the number shown in the table.
However, if the same number of output points are listed twice, you can select the larger
number of input points.

nector while carefully inserting the pins.

1) Turn off the power of the programmable
controller.

2) Remove the cover from the memory
board installation section.

3) Slowly pull up the lower section of the
memory board, and completely remove
the board.

• Before removing or installing the memory board, be sure to turn off the power.

3.11 Wiring techniques

The wiring of FX

2NC

products has been designed to be safe and easy. If during the installation
of these products or associated products concern is felt, please contact a professional electri­cian who is trained to the local and national standards applicable to the installation site.

Wiring cautions

• Do not run input signals in the same multicore cable as output signals or allow them to
share the same wire.

• Do not lay I/O signal cables next to power to power cables or allow them to share the
same trunking duct. Low voltage cables should be reliably separated or insulated with
regard to high voltage cabling.

• Where I/O signal lines are used over an extended distance consideration for voltage
drop and noise interference should be made.

3-17

FX2NC Series Programmable Controllers Installation notes 3.

3.12 Termination of connector style I/O

The I/O connector should be the 20-pin type and should conform to MIL C 83503 of Military
Standard.
This type of connector is also used for FX

2C

series programmable controllers.

The output connectors of the main unit and the connector-type 16-point output extension
blocks are the 16-point common type (8-point common type for the FX

2NC

-16MT).
These output connectors have two COM1 to COM3 pins that are connected to each other
inside the programmable controller. To connect the line to an external unit, shortcircuit
these two pins at the external circuit so that the load of each pin can be reduced.

3-18

FX2NC Series Programmable Controllers Installation notes 3.

3.13 Termination of screw terminals

Cables terminating at a screw terminal of an FX2N and FX0N product should be fitted with insu­lated crimp terminals, see example shown. Terminals screws should be tightened to between

0.5 to 0.8 Nm. Screw terminals must be secured to prevent a loose connection from causing a
malfunction.

For the 24V DC power source of the FX or FX

series programmable controllers, the cor­rection value should be written in data register D8008; a special data register that sets the
power failure detection period. However, for the FX

2NC

series programmable controllers, it
is not necessary to write the correction value.
The data stored in the D8008 register will be automatically corrected by the system pro­gram. Do not modify the D8008 data.

blocks and special function blocks. If two sources
are required, follow the below guidelines:

- Supply power to the input extension blocks and
special function blocks before or at the same
time the main unit is powered.

- The power supplies may be cut the same time
after ensuring system safety.

4.2 Earthing / Grounding

Use a cable at least 0.2mm2 (AWG24) to ground equipment. Ground resistance must be
less than 100Ω (class D). Note that the ground cable must not be connected to the same

ground as the power circuits. Grounding is recommended but if a proper ground cannot be

provided the PC will still operate correctly without being grounded.

6.2.1 Product life of relay contacts

The product life of relay contacts considerably varies depending on the load type used. Take
care that loads generating reverse electromotive force or rush current may cause poor contact
or deposition of contacts which may lead to considerable reduction of the contact product life.

1) Inductive load

Inductive loads generate large reverse electromotive force between contacts at shutdown
which may cause arcing. At a fixed current consumption, as the power factor (phase
between current and voltage) gets smaller, the arc energy gets larger.
The test results in table 6.5 were gathered from a 1 sec ON/OFF test cycle.
Please note that the over current induced by in-rush greatly reduces the relay contacts life.
The rated life for an inductive AC load such as a contactor or solenoid valve is 500,000
operations at 20VA.

0.35A/100V AC

0.15A/240V AC

0.8A/100V AC

0.33A/240V AC

The product life of relay contacts becomes considerably shorter than the above conditions
when the rush overcurrent is shut down.

* For countermeasures while using inductive loads, refer to "Output circuit configuration" below

in this section.

Some types of inductive loads generate rush current 5 to 15 times the stationary current at
activation. Make sure that the rush current does not exceed the current corresponding to the
maximum specified resistance load.

2) Lamp load

Lamp loads generally generate rush current 10 to 15 times the stationary current.
Make sure that the rush current does not exceed the current corresponding to the maximum
specified resistance load.

3) Capacitive load

Capacitive loads can generate rush current 20 to 40 times the stationary current.
Make sure that the rush current does not exceed the current corresponding to the maximum
specified resistance load. Capacitive loads such as capacitors may be present in electronic
circuit loads including inverters.

* For the maximum specified resistance load, refer to Section 6.1.

FX2NC Series Programmable Controllers Outputs 6.

6.2.2 Output circuit configuration

An internal protection circuit for the relays is not provided in the relay output circuit for this
product. It is recommended to use inductive loads with built-in protection circuits. When using
loads without built-in protection circuits, insert an external contact protection circuit, etc. to
reduce noise and extend the product life.

1) DC load
Connect a diode in parallel with the load.

The diode (for commutation) must comply with the
following specifications.

Inductive load

Reverse voltage 5 to 10 times the load voltage

Forward current Load current or more

2) AC load
Connect the surge absorber shown to the right

(combined CR components such as a surge killer
and spark killer, etc.) parallel to the load.
Select the rated voltage of the surge absorber
