3.2.2 Inputs and outputs
The list of input and output functions in section 3.2.3 is a handy instrument to help you keep track of
which inputs and outputs you will need to configure.
Analogue inputs
Analogue inputs must refer to an Agnd terminal placed in the same terminal block as the input being
wired.
Analogue inputs can, depending on the configuration, be used for either PT1000 temperature sensors
or for 0…10 V DC analogue input signals, for example from a pressure transmitter.
Digital inputs
Digital inputs must refer to +C on terminal 4. Digital inputs may only be wired to voltage-free
contacts. Any external voltage applied to a digital input may harm the unit. The input signal can be
set to either NO or NC.
Universal inputs
A universal input can be configured to act as either an analogue input or as a digital input.
A universal input configured as an analogue input can, depending on the configuration, be used for
either PT1000 temperature sensors or for 0…10 V DC analogue input signals, for example from a
pressure transmitter.
Universal inputs configured as an analogue input must refer to an Agnd terminal placed in the same
terminal block as the input being wired.
A universal input configured as a digital input must, just like other digital inputs refer to C+ on
terminal 4. It may only be wired to voltage-free contacts.
Analogue outputs
Analogue outputs must refer to the Agnd terminal placed in the AO terminal block.
All analogue outputs can be individually set to any one of the following signals:
0…10 V DC
2…10 V DC
10…0 V DC
10…2 V DC
If the Corrigo and the actuators connected to it share the same transformer it is essential that the same
transformer-pole is used as reference for all the equipment. Failure to do so will prevent the equipment
from functioning as intended and may also lead to damages.
Digital outputs
Digital outputs should normally refer to G
DO
on terminal 10. G
DO
is internally connected to G on
terminal 1 and supplies 24 V AC or DC depending on the choice of supply voltage.
All the digital outputs are controlled by MOSFET transistors. The outputs are internally connected
with G
0
and can deliver max 2 A per output. However, the total power for all the DOs must not be
over 8 A.
A number of different wiring alternatives are possible depending on the type of supply voltage to
the Corrigo and the relay type.
