PWM Outputs
The CONTROLLINO PLCs have PWM outputs (Pulse Width Modulation). These outputs are marked
with a dark background and the designation "D0" to "D..". The outputs which are marked with a
bright background cannot be used as a PWM output.
The PWM outputs are as follows:
Version
PWM Output Numbers
MINI
D1, D2, D5
MAXI
D0 ... D11
MEGA
D0 ... D11, D14, D15, D16
These outputs can be used to control lamps, DC motors or for the output of audio frequencies.
Pulse Width Modulation means that a digital output signal is generated, whose duty cycle is mod-
ulated. The duty ratio indicates the ratio of the duration of the switched-on state to the period
duration. The frequency and the level of the signal always remain the same. It only changes the
length from HIGH to LOW.
Current at Digital Outputs
At the maximum ambient temperature of 55°C:
MINI:
Digital output max total of all 8 digital outputs is 4 A. That means every digital output can be
loaded with 0,5 A at the same time.
One or max 2 digital outputs can be loaded each maximum 2 A but total current of all 8 outputs
must not exceed 4 A.
MAXI:
Digital output max total of all 12 digital outputs is 6 A. That means every digital output can be
loaded with 0,5 A at the same time.
One or max 3 digital outputs can be loaded each maximum 2 A but total current of all 12 outputs
must not exceed 6 A.
MEGA:
Digital output max total of all 24 digital outputs is 12 A. That means every digital output can be
loaded with 0,5 A at the same time.
One or max 6 digital outputs can be loaded each maximum 2 A but total current of all 24 outputs
must not exceed 12 A.
