B.3 distance 200< L< 500 m.
If one of the terminals is connected at a distance >200 m, connect it
according to the diagram described in A.3. Connect the other terminal as
described in A.1 or A.2. If both terminals are close to a distance > 200 m,
connect them as shown in the diagram below:

Case C: 3 terminals.
For the first 2 terminals refer to Case B. For the third terminal use one of
connections A.1, A.2 or A.3.
Important:
•
the 24 Vdc at +Vterm (J24) can be used only in alternative to connector
J10 to power an external terminal, with maximum current 1.5 W;
•
in networks with a star layout, if the cable is longer than 5 m, connect
the terminal only to the first or last c.pCO in the network (to avoid
branches).
The following table applies.

2: Shared terminal connection in pLAN network
To share a terminal between several c.pCO controllers, these can be
connected in a pLAN network, and the terminal connected to one of the
controllers in the network (see the figure below). The previous details on
the maximum length allowed between terminal and controller also apply
in this case.

It is possible use one terminal only, sharing it between controllers to
display the information relating to each (see the paragraph "Private and
shared terminal").
4.6 Input/output
labels
c.pCO controllers are distinguished by size and provided with inputs
and outputs and power supplies for the active probes most suitable for
various applications.
The features that depend on the model are:
•
maximum number and type of inputs/outputs;
•
availability of built-in driver for expansion valves;
•
type of interfaces
