CP1E CPU Unit Hardware User’s Manual(W479)
The following restrictions apply to the CP-series Expansion Units and CP-series Expansion I/O Units
that can be connected to CP1E CPU Units.
A total of up to three Expansion Units and Expansion I/O Units can be connected to an E30/40/60(S),
N30/40/60(S
) or NA20 CPU Unit. Expansion Units and Expansion I/O Units cannot be connected to
E10/14/20(S) or N14/20 CPU Units.
Each CPU Unit can connect one device to pin 6 (+5V power supply) of the CP1W-CIF01 built-in
RS232C port. If one CPU Unit connects two devices, a total of up to two Expansion Units can be con-
nected to the CPU Unit.
The following restrictions apply when using the CPU Unit’s external power supply.
AC-power-supply E30/40/60(S), N30/40/60(S
) or NA20 CPU Unit
The power supply capacity is restricted for AC-power-supply E30/40/60(S), N30/40/60(S
) 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 2-4-1 External Power Supply Capacity When Expansion I/O Units or Expansion Units are
Connected for details.
AC-power-supply or DC-power-supply E10/14/20(S), N14/20 CPU Unit
There is no external power supply on AC-power-supply or DC-power-supply E10/14/20(S), N14/20
CPU Units.
