c.pCO sistema +0300057EN rel. 1.2 - 29.05.2017

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 dierent 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 dierent voltages. There is

also reinforced insulation between each terminal of the digital outputs and the rest of the controller.

SSR outputs (on

models where

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.

• Maximum length: 500 m

• Max data rate: 38400 bit/s

• Maximum number of connectable devices: 32

Serial ONE BMS 1 Serial Card • Not integrated on main board

• HW driver: not present

• Can be used with all pCO family optional BMS cards

Serial TWO FieldBus 1 Serial

Card

• Not integrated on main board

• HW driver: not present

• Can be used with all pCO family optional FieldBus cards

Serial THREE BMS 2 / J25 • Integrated on main board

• HW driver: asynchronous half duplex RS485 Slave

• Optically-isolated/not optically-isolated serial (*)

• 3-pin plug-in connector, 5.08 pitch

• Maximum length: 1000 m

• Max data rate: 115200 bit/s

• Maximum number of connectable devices: 16

Serial FOUR FieldBus 2 / J26

(and J23 on Large

and Extralarge

version)

• Integrated on main board

• HW driver: asynchronous half duplex RS485 Master/Slave (**)

• J23: not optically-isolated

• J26: optically-isolated/ not optically-isolated

• 3-pin plug-in connector, 5.08 pitch

• J23 and J26 are both managed by the same protocol as serial

4, with the advantage of being electrically independent.

(*): both models are available; (**): port J26 can be congured: 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.
