Insulation distance
The relay outputs have different features depending on the model of pCO
The outputs can be divided into groups. There is double insulation between the groups (cells in the table) and consequently these may have
different voltages. There is also double insulation between each terminal of the digital outputs and the rest of the controller. The relays
belonging to the same group (individual cells in the table) have basic insulation and therefore must have the same power supply (24 Vac or
230 Vac).

Warnings:
Warnings:Warnings:
Warnings:
• The groups that the digital outputs are divided into have two common pole terminals to simplify wiring;
• make sure that the current running through the common terminals does not exceed the rated current of an individual terminal, that is, 8 A.
