3.6.4 D igital outputs
Electromechanical relay digital outputs
The controller provides digital outputs with electromechanical relays; for easier assembly, the common terminals for some relays
have been grouped together. Some relays are equipped with changeover contacts. Also see the technical specifi cations table
in 0300057EN.

Tab. 3.p
The following tables apply in relation to the type of insulation.
Insulation type on k.Air mini andc.pCOe
Between relays in group 1 (R1, R2) and 2 (R3, R4, R5) basic
Between relays in group 3 (R6) and relays in group 1 and 2 reinforced
Tab. 3.q
Note:
• there is basic insulation between groups 1 and 2, and therefore these must have the same voltage (generally 24 Vac or
110/230 Vac);
• between relays in groups 1 and 2 and in group 3 there is reinforced insulation, therefore group 3 can have a diff erent voltage.
Insulation type on k.Air large
Between relays in the same group basic
Between groups of relays reinforced
Between relays and the rest of the controller reinforced
Tab. 3.r
Note:
• within a group, the relays have functional insulation and therefore must have the same voltage (generally 24 Vac or 110/230 Vac);
• between groups of relays there is reinforced insulation, therefore the groups can have diff erent voltages.
