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.
Relay Outputs
The relay outputs "R0" to "R.." can be used to connect and switch external circuits. The contact
type as well as the contact connections are marked on the PLCs. The maximum permissible
switching current per relay is 6A (at 250V / AC) or 6A (at a maximum of 30V / DC). The relay
outputs are potential free!
The CONTROLLINO MAXI and MEGA are equipped with LEDs to display the switching status of the
relays with the labelling "R0" to "R..". The corresponding LED lights up when the relay is energized.
In case of the CONTROLLINO MINI, the relays are connected parallelly to the digital outputs D0-
D5 and thus are named D0-D5.
Number of relays depending on version:
