Connecting Expansion Unit and Expansion I/O Units
Up to seven Expansion Units and Expansion I/O Units can be connected when a CP1H CPU Unit is used, but the
following restrictions apply. Observe these restrictions when using the models in the shaded areas in the
following tables. A maximum total of 15 input words is allocated for Expansion Units and a maximum total of 15
output words is allocated for Expansion Units and Expansion I/O Units.

For example, the CP1W-TS002 Temperature Sensor Unit is allocated
four words per Unit, so no more than three Units can be connected (4
words x 3 Units = 12 words). It would then be possible to mount a
combination of other Units to use the remaining three input and 15
output words.

Output
• I/O Connecting Cable can be connected to any Unit from the CP1H/CP1L CPU Unit to the third Expansion Unit or
• Only one I/O Connecting Cable can be used in each CP1H or CP1L PLC.
• Even when I/O Connecting Cable is used, the above restrictions on the number of connectable CP1W/CPM1A
Up to two CJ-series Special I/O Units or CPU Bus Units can be connected by using a CP1W-EXT01 CJ Unit
Adapter. The number of Units that can be used is as described below.
Use CP1W-CN811 I/O Connecting Cable when
using CP1W/CPM1A Expansion Units and
Expansion I/O Units at the same time as a CJ
Unit Adapter. In this situation, the number of
CP1W/CPM1A Expansion Unit and Expansion
I/O Units that can be connected is subject to
the restrictions described above. Only one I/O
Connecting Cable can be used.
CP1H CPU Unit, the maximum number of Units that can be used is two CJ-series Units and seven
CP1W/CPM1A Expansion Units and Expansion I/O Units.
The current consumption for the CP1H must be no more than 2 A for 5 V and 1 A for 24 V, and the total
current consumption must be no more than 30 W.
Check the total current consumption to be sure these limits are not exceeded referring to page 29 for the
CP1H CPU Unit and CP1W Expansion Unit and Expansion I/O Unit current consumptions and to the above
table for CJ-series Unit current consumptions.
Expansion I/O Unit (i.e., the fourth Unit).
Expansion Units and Expansion I/O Units still apply.
