The pCO also features a version with solid state relays (SSR) for controlling devices which require an unlimited number of switching cycles and thus would not be
supported by electromechanical versions. This outputs are dedicated to loads powered at 24Vac/Vdc with a maximum power Pmax = 10W.

Warning:
Warning:Warning:
Warning: the load of the SSR relay is powered at 24Vac/Vdc, thus all the other terminals in the group, from 1 to 6, must be powered with the same tension due to the
absence of double insulation within the group. Moreover, terminals from 1 to 6 can be powered at 110 to 230 Vac using a safety transformer (Class 2).

If the product is installed in industrial environments (application of the EN 61000-6-2 standard) the length of the connections must be less than 30m.
In any case, this length should not be exceeded so as to prevent measurement errors.
