Compact PLC series
CPM2C
A versatile controller for up to 192 I/O points in an
ultra-compact package
SYSMAC CPM2C
An extensive range of models assures efficient machine
control in an ultracompact package. CPU Units (DC
power supply only) are available with relay or transistor
output, terminal block or various connector options, and
an optional real-time clock function. Select the output
type, number of I/O points and other specifications to
meet your needs. Expansion I/O Units with 8 to 32 I/O
points make it possible to configure a control system
with a maximum of 192 I/O points.

CPM2C Power Consumption
Use the following power consumption tables to calculate the total power
capacity required when using a CPM2C PLC. The rated output for the
CPM2C-PA201 AC Power Supply Unit is 15 W. Any surplus power not
required for the PLC directly can be used as service power supply for
sensors and other devices.

Memory backup:
The read/write DM area, HR area, AR area, and counter values are backed up. With CPU Units that are equipped with a clock, the
battery will backup memory for 2 years at 25° C. With CPU Units that are not equipped with a clock, if a battery is not installed, the
internal capacitor will backup memory for 10 days at 25° C. If a battery (optional CPM2C-BAT01 Battery) is installed, it will backup
memory for 5 years at 25° C.
