Universal inputs configured as an analog input must refer to an
Agnd
terminal.
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.
Analog outputs
Analog outputs must refer to a Agnd terminal.
All analog outputs can be individually set to any one of the following output signals:
✓
0…10 V DC
✓
2…10 V DC
✓
10…0 V DC
✓
10…2 V DC

onn!! If the controller and its connected actuators share the same transformer, it is essential that
the same transformer pole is used as reference for all the equipment. The equipment may otherwise
not function as intended and may also suffer 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 exceed 8 A.
A number of different wiring alternatives are possible depending on the type of supply voltage to the
controller and the relay type.
