Supply Voltage Terminal (12 / 24V DC)
The connection "12V / 24V" of the upper terminal block and the adjacent "GND" connection is
used for the voltage / current supply of the CONTROLLINO controls. The CONTROLLINO controls
can alternatively be operated with a 12V or 24V voltage supply. The permissible supply voltage is
12V (between 10.8V-13.2V) or 24V (between 21.6V-26.4V) (DC, direct current).
IMPORTANT! Please make sure only to use a stabilized supply voltage!
The maximal supply current differs according to the type of CONTROLLINO you are using. You can
find it in the following table.
CONTROLLINO
used internal fuse
MINI
8A, automotive fuse
MAXI
20A, automotive fuse
MEGA
30A, automotive fuse
Exceeding the maximum current would lead to a fusing of the internal fuse of the CONTROLLINO.
The correct voltage supply is indicated by two LEDs with the description "12V" and "24V" on the
front panel of the unit. The LEDs light up differently, depending on the supply voltage of "12V" or
"24V". The following table shows the states.
The LEDs for the operating voltage states are:
12V LED
24V LED

INFO: After connecting the supply voltage or pressing the Reset-button CONTROLLINO performs
all necessary initializations and then immediately starts the loaded user program.
