CMOD-02 multifunction extension module (external
24 V AC/DC and isolated PTC interface)
￭

Product overview

The CMOD-02 multifunction extension module (external 24 V AC/DC and isolated PTC
interface) has a motor thermistor connection for supervising the motor temperature and
one relay output, which indicates the thermistor status. In case the thermistor overheats,
the drive trips on motor overtemperature. If Safe torque off tripping is required, the user
must wire the overtemperature indication relay to the certified Safe torque off input of
the drive.
In addition, the extension module has an external power supply interface, which can be
used to power up the drive control unit in case the drive power supply is not on. If you
do not need the back-up power supply, you do not have to connect it because the module
is powered from the drive control unit by default.
There is reinforced insulation between the motor thermistor connection, the relay output
and the drive control unit interface. Thus, you can connect a motor thermistor to the
drive through the extension module.
Note: With CCU-24 control unit, a CMOD-02 module is not necessary for external
24 V AC/DC supply connection. The external supply is connected directly to terminals
40 and 41 on the control unit.
