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