c.pCO SMALL, MEDIUM, BUILT-IN DRIVER, LARGE, EXTRALARGE
Type Relay. Min. contact current: 50 mA.
Maximum no. 8: SMALL; 13: MEDIUM/ BUILT-IN DRIVER; 18: LARGE; 29: EXTRALARGE
Insulation distance
The relay outputs have different features depending on the controller model. The outputs can be divided into groups. Relays belon-
ging to the same group (individual cell in the table) have operational insulation and must therefore be powered at the same voltage.
Between groups (between cells in the table) there is reinforced insulation, so the relays can be powered at different voltages. There is
also reinforced insulation between each terminal of the digital outputs and the rest of the controller.

SSR outputs (on

provided)
Maximum number 1: SMALL (output 7); 2: MEDIUM-EXTRALARGE (outputs 7 and 12); 3 or 4: LARGE (outputs 7, 12, 14 or 7, 12, 14, 15)
Working voltage 24 Vac/Vdc SELV 230Vac
Load current (MAX) 1 A 70mA
Pulse load current (MAX) 1,2 A 150mA
Warning:
•
if the load requires a higher current, use an external SSR. To power external loads, use the same power supply as the pCO (connected to terminals G-G0); this must
always be dedicated and not in common with the power supply to other devices (e.g. contactors, coils, etc.);
•
to simplify wiring, the groups of digital outputs have two common pole terminals;
•
make sure that the current running through the common terminals does not exceed the rated current of each terminal, i.e. 8A.

Serial FOUR FieldBus 2 / J26
(and J23 on Large
and Extralarge
version) • Integrated on main board
• HW driver: asynchronous half duplex RS485 Master/Slave (**)

(*): both models are available; (**): port J26 can be configured: see par. 3.2.
Note :
in industrial/residential applications with distances greater than 10 m, use shielded cable with earthed shield.
In residential applications (EN 55014), regardless of cable length, in versions without valve driver, the connection cable between controller and terminal and
the serial cable must be shielded and earthed on both sides.
