(11) Expansion I/O Unit Connector
CP-series Expansion I/O Units and Expansion Units (Analog I/O Units,
Temperature Sensor Units, CompoBus/S I/O Link Units, or DeviceNet I/O
Link Units) can be connected. Up to three Expansion Units or Expansion
I/O Units can be connected to a CPU Unit with 30 or 40 I/O points and
one Expansion Unit or Expansion I/O Unit can be connected to a CPU
Unit with 20 or 14 I/O points. (For details on using Expansion Units and
Expansion I/O Units, refer to
SECTION 7 Using Expansion Units and
Expansion I/O Units
.)
(12) Output Indicators
The output indicators light when output terminal contacts turn ON.
(13) External Power Supply and Output Terminal Block

CP1W-CIF01 RS-232C Option Boards
An RS-232C Option Board can be mounted to an Option Board slot on the
CPU Unit. With a CPU Unit with 30 or 40 I/O points, either Option Board slot
may be used.
When mounting an Option Board, first remove the slot cover. Grasp both of
the cover's up/down lock levers at the same time to unlock the cover, and then
pull the cover out.
Then to mount the Option Board, check the alignment and firmly press it in
until it snaps into place.
!Caution
Always turn OFF the power supply to the PLC before mounting or removing
an Option Board.
External power
supply terminals
CPU Units with AC power supply specifications have
external 24-VDC, 300-mA, power supply terminals.
(except for the CP1L-L
@
DR-A, which has a 200-mA
power supply terminals). They can be used as service
power supplies for input devices.
Output terminals
Used for connecting output devices.
