System Configuration Section 1-2
CPU Units with 14 or 20 I/O Points and AC Power (CP1L-L@@DR-A and
CP1L-L@@DT@-A)
When CP1W or CPM1A Expansion Units or Expansion I/O Units are con-
nected to a CPU Unit with 14 or 20 I/O Points and AC Power (CP1L-L@@DR-
A and CP1L-L@@DT-A), the external power supply cannot be used. If no
Expansion Units or Expansion I/O Units are connected, up to 200 mA can be
used.
CPU Units with DC Power
CPU Units with DC power do not have an external power supply.
■ Restrictions on the number of simultaneously ON output points
CP1W-32ER/32ET/32ET1’s maximum number of simultaneously ON points is
24 (75%).
■ Restrictions Imposed by Ambient Temperature
There are restrictions in the power supply voltage and output load current
imposed by the ambient temperature for CPU Units with DC power. Use the
CPU Unit within the following ranges of power supply voltage and output load
current.
CPU Units with Relay Outputs (CP1L-
@@@DR-D)
Relay Output Load Current Derating Curves for CPU Units and Expansion I/O
Units
Note The above restrictions, apply to the relay output load current from the CPU
Unit even if Expansion I/O Units are not connected.
