Expandable Cpu Units; Connection Methods - Omron SYSMAC CP1E-E20DR-A Datasheet

Specifications of Expansion I/O Units and Expansion Units

Expandable CPU Units

• Expansion I/O Units and Expansion Units cannot be connected to E10/14/20 or N14/20 CPU Units.
• A total of up to three Expansion I/O Units and Expansion Units can be connected to an E30/40, N30/40/60 or NA20 CPU Unit.
●CP1E E10/14/20 or N14/20 CPU Unit
●CP1E E30/40, N30/40/60 or NA20 CPU Unit

Connection Methods

Connection cables for the Expansion I/O Units and Expansion Units are used to connect the Units. The length can be extended by using a CP1W-
CN811 I/O Connection Cable (length: 800 m).

Restrictions on External Power Supply Capacity
The following restrictions apply when using the CPU Unit's external power supply.
●AC-power-supply E30/40, N30/40/60 or NA20 CPU Unit
The power supply capacity is restricted for AC-power-supply E30/40, N30/40/60 or NA20 CPU Units. It may not be possible to use the full 300 mA
of the external power supply, though a CPU Unit can connect any CP-series Expansion I/O Unit or Expansion Unit.
The entire 300 mA from the external power supply can be used if Expansion Units and Expansion I/O Units are not connected.
Refer to the CP1E CPU Unit Hardware Manual (Cat. No. W479) for details.
●AC-power-supply or DC-power-supply E10/14/20, N14/20 CPU Unit
There is no external power supply on AC-power-supply or DC-power-supply E10/14/20, N14/20 CPU Units.
CP1E-E@@D@-@ CP1E-N@@D@-@/NA20D@-@
A total of up to three CP-series Expansion I/O Units
and Expansion Units can be connected.
