Analogue Outputs; Digital Outputs - Carel pCO3 Hoja De Instrucciones

Analogue outputs

type 0 to 10 Vdc optically-isolated
maximum number 4, 4, 6, on the SMALL, MEDIUM and EXTRALARGE N.O./N.C., LARGE boards respectively
power supply external 24 Vac/Vdc
resolution 8 bit
maximum load 1 k (10 mA)
precision ± 2 % of end scale on outputs: Y1, Y2, Y3 and Y4
-2%/+5% of end scale on: Y5 and Y6

Digital outputs

type relay
maximum number 8: SMALL; 13: MEDIUM; 18: LARGE; 27: EXTRALARGE N.C.; 29: EXTRALARGE N.O.
For the requirements refer to Figs. 3 to 5 (reference NO*, NC* and C*). Note the presence of outputs with changeover contacts kept separately (that is,
without the poles shared between different outputs). Groups from 2 to 5 outputs have 2 "common" poles for easy assembly. Make sure that the current
running through the common terminals does not exceed the rated current of each individual terminal, that is 8A.
Insulation distance the outputs can be divided into groups. There is double insulation between groups (between cells in the table).
Note: the relays in the same group must have the same power supply (24 or 230 Vac).

Note: the relays in the individual cells of the table have basic insulation between them, while between groups (cell-cell)
there is double insulation.

where featured) 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); as
specifi ed by Carel, this must always be dedicated and not in common with the power supply to other devices on the electrical
panel (such as contactors, coils, etc.).
Make sure that the load connection cables are as short as possible and away from power cables. For the connection diagrams
see the pCOSistema manual +0300009IT.
