. One resettable PTC per M12 socket protects the sensor
supply. The maximum current draw for the sensor power supply is 200 mA for each M12 socket. Please

CAUTION:
Please note that the sum current of all sensors and modules supplied via the bus
node in a Cube67 system may not exceed 9 A.
CAUTION:
Sensors can only be supplied via the bus node in a Cube67 system. Feedback
by sensors or an external power supply (in order to increase the max. current) is not
permissible.
ATTENTION:
Capacity per digital input is 10 nF.
ATTENTION:
The maximum permitted capacitance may not exceed 220 µF.
