The pCO² features up to 18 digital outputs with electromechanical relays; upon request with solid state relays (SSR).
To simplify assembly the common terminals of some relays have been grouped together. If the diagram in Fig. 4.7.1 is used, WKH

The relays are divided into groups, according to the distance of insulation. Inside each group, the relays have just single
insulation and thus must have the same voltage (generally 24Vac or 110÷230Vac). Between the groups there is double insulation
and thus the groups can have different voltages.
