Note:
•DC5V/GND: Logic circuit operation power supply for the
extension module, provided by the extension bus
•DC24V/COM: Power supply for input state detection,
provided through the 24V terminal of the main module or by
an external switch-mode power supply of 24 V.
•DC24V/GND: Relay circuit operation power supply for the
extension module, provided by the extension bus
Before connecting an extension module to the main module, you
need to calculate the current consumption sum of all the power
supplies. Ensure that the sumof the current consumption is lower
than the output current of the main module power supply to
prevent overload of the power supply.
The solution to insufficient capacity of the power supply is to use
extension modules with built-in power supplies. Such modules
not only supply power for themselves, but their DC5V/GND,
DC24V/COM, and DC24V/COM output can also supply power for
subsequent extension modules.
4 Input characteristics
4.1 Internal equivalent input circuits
The extension module needs to connect to an external power

supply (24 V DC) for user switch state detection. The internal
equivalent resistance of the input circuit is about 5 kΩ, and the
signals are detected by using a bidirectional optocoupler. You
can select the source-type or sink-type mode, but ensure that the
dry contact switch signal is connected. If the output signal of an
active transistor sensor, the OC output mode signal is required.
The internal equivalent power supplies and input signal wiring are
similar to those of the input circuits of the main module, as shown
in Figure 4-1.

4.2 Input/output signal state indication
The state of a user input terminal can be indicated by an input
LED indicator. When the input port is switched on (in the ON
state), the input indicator is on; and when it is switched off, the
input indicator is off.
The state of an output port can be indicated by an output LED
indicator. When the output port is switched on (in the ON state,
Yn and COMn are connected), the output indicator is on; and
when it is switched off, the output indicator is off, as shown in
Figure 4-2.

5.3 Output connection instance
Figure 5-1 shows the connection of IVC3-1616MAT and
IVC-EH-0808ENR. The output groups can be connected to
different signal voltage circuits. For examples, the output group
Y4-COM2 can be connected to the +24V DC circuit, and the
power can be supplied by DC24V/COM of the controller; the
output group Y6-COM3 can be connected to the +5V DC
low-voltage signal circuit; that is, different output groups can
operate in circuits with different voltage classes.

6 Extension module connection
6.1 Extension bus connection
Ensure that the main module is not powered on. Remove the
small cover of the extension cable socket on the right side of the
main module, and then insert the bus cable terminal of the
extension module to the socket. If multiple extension modules are
to be connected, you can connect them in sequence. Note that
extension cable socket covers are detachable parts. Do not lose
themafter removing them fromthe main module.
Figure 6–1 Diagram of extension module connection in series
mode
6.2 Extension module addressing
IVC3 series PLCs automatically identify extension modules that
are connected to them and automatically perform sequential
addressing on the extension modules. No user operation is
required.
Automatic addressing is performed once after the PLC is properly
powered on, and then the addresses of all the extension modules
do not change in the running. Do not insert or remove any I/O
extension module or special function module when the PLC is
running. Otherwise, the PLC may be damaged or operation
exceptions may be caused.
Extension modules with power supplies must be powered on
simultaneously with or before the main module to ensure effective
addressing on the extension modules.
The octonary system is adopted for numbering I/O points, for
example, 0, 1, 2, 3, 4, 5, 6, 7, 10, 11, 12, 13, 14, 15, 16, 17, 20,
21, … The digits 8 and9 are not used.
Input ports of the main module and extension modules are
numbered X0, X1, X2, … X7, X10, X11, …; and output ports are
numbered Y0, Y1, Y2, …Y7, Y10, Y11, … The point numbers are
grouped with 8 number in one group, and the groups with less
than 8 point number are left out.
For example, IVC3-1616MAT provides 16 input points, which are
numbered X0 to X17. No terminal is numbered X24 to X27. The X
terminal of a subsequent extension module is numbered from
X30. In the same way, if 12 output points are provided, they are
numbered Y0 to Y13, and no terminal is numbered Y14 to Y17;
and the Y terminals of subsequent extension modules are
numbered from Y20.
The X terminals and Y terminals of I/O extension modules are
numbered in ascending mode based on the sequence they are
connected to the extension connectors of the main module.
The following table describes logical numbering examples of the
ports of the main module and extension modules.
