Connection and operating elements
The CONTROLLINO PLCs are equipped with screw terminals for the connection of external com-
ponents. The wire strength for the screw terminals at the bottom should have a recommended
cross-section.
Model MINI
For supply conductors: DC 24 V use of 1mm
2
to 2,5mm
2
(AWG16 to AWG13 ), with temperature
rating at least 90C.
Model MAXI
For supply conductors: DC 24 V use of 2,0 mm
2
to 2,5mm
2
(AWG12 to AWG13), with temperature
rating at least 90C.
Model MEGA
For supply conductors: DC 24 V use of at least 2,5 mm
2
to 4mm
2
(AWG12 to AWG 12), with tem-
perature rating at least 90C.
All models
For Relay outputs (6 A) use conductors of at least 0,75 mm
2
to 4 mm
2
(AWG18 to AWG12), with
temperature rating at least 90C.
For Digital outputs (2 A) use conductors of at least 0,5 mm
2
to 1,0 mm
2
(AWG20 to AWG 17) with
temperature rating at least 90C.
For inputs and RS485 interface use any kind of conductor cross section due to the small input
current with temperature rating at least 90C.
In addition, the CONTROLLINO PLCs have one or more pinheader connectors with a grid size (RM)
of 2.54mm. Here you can attach jackbars with flat ribbon cables or so-called "jump-wire" for ex-
perimental setups. The following illustrations show the three types of CONTROLLINO controls and
their connection and operating elements.
All connected cables including power cables shall not exceed length of 30 m.
INFO: on http://www.controllino.biz you can download a "PINOUT table". In this table you can
easily see all internal wiring between terminals and the microcontroller.
